--- title: Unauthenticated CRUD on /api/providers and Full API Key Leak via /api/usage/stats product: 9Router version: = 0.4.41 severity: critical cverequest: true --- Summary Multiple critical API security vulnerabilities were discovered in 9Router's Next.js dashboard. The /api/providers endpoin...

Coder's workspace app CORS origin check can be bypassed via UUID-based subdomain spoofing

Summary Coder's subdomain-based workspace app proxy allowed the same-owner CORS check to be bypassed. When a workspace-name subdomain segment parsed as a UUID, the workspace was resolved by ID without confirming the URL's username matched the real owner, while the CORS middleware trusted the...

Linuxfabrik Monitoring Plugins have local privilege escalation using embedded command

Summary When a check plugin places user provided input inside a command which is passed to shellexec, an attacker can abuse this to run arbitrary commands. This is mainly dangerous for plugins which are listed in the sudoers file, because this allows an attacker controlling the nagios user to get...

Coder vulnerable to stored HTML injection via workspace agent logs in AgentLogLine component

Summary The AgentLogLine dashboard component instantiated ansi-to-html without escapeXML: true and inserted the result via dangerouslySetInnerHTML so HTML embedded in workspace agent log lines was rendered as live markup. Server-side sanitization did not neutralize HTML metacharacters. Note:...

Coder's AI Bridge Proxy skips TLS certificate verification in default configuration

Summary The AI Bridge Proxy aibridgeproxyd created a goproxy server whose default transport set InsecureSkipVerify: true and only assigned a secure transport when an upstream proxy was configured. In the default configuration no upstream proxy, outbound HTTPS to the Coder access URL accepted any...

Suspended Coder users retain access to AI Bridge LLM proxy endpoints

Summary AI Bridge proxy endpoints authenticate via Server.IsAuthorized in coderd/aibridgedserver, which validates key format, expiry, secret and deleted or system users but does not check whether the account is suspended. Because suspension does not revoke existing API keys, a suspended user's...

Coder vulnerable to denial of service via unbounded request body in AI Bridge provider endpoints

Summary AI Bridge provider handlers read request bodies with io.ReadAll without a maximum size so an authenticated user with AI Bridge access could send an arbitrarily large body and exhaust memory. Note: Exploitation requires authenticated access to the AI Bridge endpoints and the impact is...

Coder: Devcontainer recreate endpoint missing write authorization allows read-only roles to destroy containers

Summary The devcontainer recreate endpoint relied on route middleware that checked only ActionRead on the workspace and, unlike the sibling delete endpoint, performed no ActionUpdate check before triggering the destructive rebuild. Note: Exploitation requires an existing low-privilege role with...

Coder's sub-agent app registration bypasses template port-sharing policy enforcement

Summary The CreateSubAgent RPC did not validate a requested app sharing level against the template's MaxPortSharingLevel before persisting workspace apps, letting a workspace owner exceed the administrator's configured maximum. Note: Exploitation requires the ability to register sub-agent apps in...

Coder's session token leaked to arbitrary hosts via `coder open app` for external workspace apps

Summary coder open app opens external workspace-app URLs without validating the scheme or host. When an external app URL contains the $SESSIONTOKEN placeholder the CLI replaces it with the user's real session token before handing the URL to the OS open handler. Note: Practical exploitation requir...

Coder: Zip upload decompression lacks aggregate size limit, enabling denial of service

Summary POST /api/v2/files converts zip uploads to tar in memory via CreateTarFromZip, which enforced a per-entry size limit but no aggregate limit on total decompressed output, writing to an unbounded in-memory buffer. Note: Exploitation requires authenticated file-upload access and the impact i...

Coder's subdomain workspace app routing trusts unauthenticated X-Forwarded-Host header, enabling cross-app data access

Summary The workspace app proxy resolves the target app from httpapi.RequestHost which prefers the X-Forwarded-Host header over the real Host header. No middleware strips X-Forwarded-Host before routing and the header is not browser-forbidden so client-side JavaScript can set it on fetch calls...

Coder: Route hijacking through lack of validation of agent-supplied AllowedIPs in tailnet coordinator

Summary The tailnet coordinator validates that an agent's Addresses derive from its authenticated UUID but applies no equivalent check to AllowedIPs. The coordinator forwards agent-supplied AllowedIPs verbatim to tunnel peers which install them into the WireGuard peer configuration. Impact A...

Coder's workspace app upsert allows cross-workspace agent rebinding via user-controlled app ID

Summary UpsertWorkspaceApp overwrites an existing app's agentid on a primary-key conflict and insertAgentApp accepts the app ID from the provisioner's CompleteJob payload without verifying it belongs to the workspace being built. CompleteJob runs under dbauthz.AsProvisionerd so the authorization...

Coder's unbounded memory allocation in provisioner file upload allows authenticated denial of service

Summary NewDataBuilder in provisionersdk/proto/dataupload.go allocated a byte slice using the client-supplied FileSize from a DataUpload message without an upper-bound check. Although the DRPC wire limit is 4 MiB, the FileSize value itself was unconstrained Impact An authenticated user able to...

Coder vulnerable to SSH config injection via unsanitized server-supplied values in `coder config-ssh`

Summary coder config-ssh wrote server-supplied SSH settings HostnameSuffix, SSHConfigOptions into the user's /.ssh/config without sanitizing embedded newlines or restricting directives so a malicious or compromised Coder server could inject arbitrary SSH configuration. Note: Practical exploitatio...

Coder: User-admin role can reset owner account password

Summary The PUT /api/v2/users/user/password endpoint authorized only ActionUpdatePersonal and did not prevent a user-admin from resetting an owner account's password. It also did not require the current password when an admin reset another user's password. Note: Exploitation requires the privileg...

Coder vulnerable to OIDC account takeover via email-based user matching and email_verified bypass

Summary Two flaws in Coder's OIDC login chained into account takeover: email-based user matching fell back to linking by email without checking for an existing link to a different IdP subject and the emailverified claim was only enforced when present as a boolean false so an absent or non-boolean...

Coder's OIDC email_verified type coercion bypass enables account takeover via unverified email linking

Summary Coder's OIDC callback checked emailverified with a direct Go bool type assertion. When an IdP returned the claim as a non-boolean for example the string "false" or omitted it, the assertion failed open and the email was treated as verified. Combined with an unconditional email-based accou...

OpenRemote has an incomplete fix for CVE-2026-40882: XXE in KNXProtocol.startAssetImport() allows arbitrary file read via unprotected XMLInputFactory

Summary The fix for CVE-2026-40882 addressed only the Velbus asset import handler. The KNX asset import handler KNXProtocol processes user-uploaded ETS project ZIP files through Saxon XSLT and XMLInputFactory.newInstance with no XXE protection, allowing any authenticated user to read arbitrary...

OpenRemote has Cross-Realm User Information Disclosure in UserResourceImpl

Summary A realm admin of tenant B can read the profile, client roles, and realm roles of any user in any other realm including the master realm by supplying the target user's UUID in the REST API path. Three read endpoints in UserResourceImpl check whether the caller holds the read:admin role but...

CiliumLocalRedirectPolicy addressMatcher allows cross-namespace service traffic hijacking and can break service translation

Impact Users with the ability to create CiliumLocalRedirectPolicies can specify arbitrary ClusterIPs via addressMatcher, which enables hijacking traffic to Services in any namespace, bypassing the namespace-scoping guarantees enforced by serviceMatcher. In addition, deleting such a policy can...

GoFiber never set HSTS header in helmet middleware due to incorrect protocol check

Summary The helmet middleware in gofiber/fiber never sets the Strict-Transport-Security HSTS response header, even when HSTSMaxAge is explicitly configured, because the condition check at helmet.go:67 uses c.Protocol — which returns the HTTP protocol version string e.g., "HTTP/1.1", "HTTP/2.0" —...

Langroid: handle_message() executes user-supplied tool JSON without sender verification

Summary A Langroid application exposing a chat interface to untrusted users may allow direct tool invocation via raw JSON payloads, even when tools are registered with use=False, handle=True. Details enablemessage..., use=False, handle=True only prevents the LLM from being instructed to generate...

Langroid: Sandbox Escape to Remote Code Execution via Incomplete `eval()` Mitigation in TableChatAgent

Advisory Details Title: Sandbox Escape to Remote Code Execution via Incomplete eval Mitigation in TableChatAgent Description: Summary Langroid is vulnerable to a critical Sandbox Escape leading to Remote Code Execution RCE in its TableChatAgent and VectorStore capabilities. When these agents...

Langroid: SQLChatAgent dangerous-function blocklist can be bypassed with quoted or schema-qualified pg_read_file calls

SQLChatAgent validatequery dangerous-pattern regex is bypassable via quoted/commented/qualified function names Summary The SQLChatAgent SQL-injection mitigation, with default allowdangerousoperations=False, combines a raw-text regex blocklist DANGEROUSSQLPATTERNS with a sqlglot SELECT-only...

Dragonfly scheduler v1 and v2 gRPC unauthenticated SSRF via attacker-controlled PeerHost in DownloadTinyFile

Summary The Dragonfly scheduler's v1 gRPC service contains an unauthenticated Server-Side Request Forgery SSRF. When a peer reports a successful download of a TINY task, the scheduler calls Peer.DownloadTinyFile and issues an HTTP GET to a host and port taken verbatim from the attacker-controlled...

Linuxfabrik Monitoring Plugins allow insecure creation of SQLite databases

Summary The SQLite databases are created at predictable static paths in /tmp. Any user can therefore create a symlink at these paths in /tmp pointing to arbitrary files. The monitoring scripts then follows these symlinks and then creates their database at the symlink target. This becomes really...

Craft CMS: Authenticated "assets/preview-thumb" discloses signed fallback transform preview link to CP users without asset-view permission

Summary A user with Control Panel access but without permission to view a target private asset can call assets/preview-thumb and receive preview HTML that contains a signed fallback transform link for that private asset. Details Root-cause analysis: 1. The endpoint accepts an attacker-controlled...

Decompress: Archive extraction can create files and links outside of the target directory

Impact When extracting an archive to a directory, a crafted archive can read or write files outside that directory. The flaw is in the code that writes the parsed entries, so it affects every format decompress handles: tar, tar.gz, tar.bz2, and zip by default, plus any others added through the...

printenv: environment variables with invalid UTF-8 are silently skipped (evades inspection)

The printenv utility in uutils coreutils fails to display environment variables containing invalid UTF-8 byte sequences. While POSIX permits arbitrary bytes in environment strings, the uutils implementation silently skips these entries rather than printing the raw bytes. This vulnerability allows...

uucore: safe_traversal TOCTOU protection only enabled on Linux

The safetraversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use TOCTOU symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize...

mv: symlinks expanded during cross-device move (resource exhaustion / data duplication)

When moving directories across filesystems, uutils mv dereferences symlinks inside the tree, copying their targets as real files/dirs instead of preserving the symlinks. GNU preserves symlinks by default. E.g. a etclink - /etc inside the source becomes a full copy of /etc at the destination...

cp: -R reads device nodes as streams, destroying device semantics

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...

rm: 'rm -rf ./' (and ./// variants) silently deletes current directory contents, bypassing dot protection

rm -rf . is correctly refused, but cleantrailingslashes normalizes ./// to ./ while pathiscurrentorparentdirectory only matches ./.. and /.//.., not ./ or ../. So rm -rf ./ recursively deletes the directory's contents and then prints a misleading cannot remove './': Invalid input. Impact: all...

comm: FIFO/pipe inputs are drained before comparison (data loss / hang)

The comm utility in uutils coreutils incorrectly consumes data from non-regular file inputs before performing comparison operations. The arefilesidentical function opens and reads from both input paths to compare content without first verifying if the paths refer to regular files. If an input pat...

id: groups= computed from real GID instead of effective GID

The id utility in uutils coreutils miscalculates the groups= section of its output. The implementation uses a user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils. Because many scripts and automated processes...

mkdir: -m exposes directory with umask perms before chmod (race window)

The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions typically 0755 before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces ...

rm: --preserve-root bypassed via a symlink to / (string check instead of dev/inode)

The --preserve-root check uses a path-string test path.hasroot && path.parent.isnone rather than comparing device/inode. A symlink to / e.g. /tmp/rootlink - / has a parent component, so it passes the check. GNU caches /'s dev/inode at startup and compares every traversed directory against it...

id: pretty-print uses effective GID instead of effective UID for name lookup

The id utility in uutils coreutils exhibits incorrect behavior in its "pretty print" output when the real UID and effective UID differ. The implementation incorrectly uses the effective GID instead of the effective UID when performing a name lookup for the effective user. This results in misleadi...

kill: 'kill -1' parsed as PID -1, sending SIGTERM to all processes (system crash / DoS)

kill -1 is incorrectly parsed as a positional pid = -1; combined with the default SIGTERM this calls kill-1, SIGTERM, signaling nearly every process the caller can see. GNU kill recognizes -1/-9 as signals and reports "not enough arguments". $ kill -1 uutils: kill-1, SIGTERM - mass termination /...

install -D: symlink race in directory creation allows arbitrary file overwrite

The -D path runs fs::createdirall on a pathname then later opens the destination via path-based File::create/fs::copy, neither anchored to a directory fd. Between the two, an attacker can replace a path component with a symlink, redirecting the write. Impact: an attacker with concurrent write...

cut: -s (only-delimited) ignored when delimiter is a newline

The cut utility in uutils coreutils incorrectly handles the -s only-delimited option when a newline character is specified as the delimiter. The implementation fails to verify the onlydelimited flag in the cutfieldsnewlinechardelim function, causing the utility to print non-delimited lines that...

install: TOCTOU symlink race (unlink-then-create without O_EXCL) allows arbitrary file overwrite

copyfile in install/src/install.rs removes the destination then recreates it by pathname via File::create / fs::copy without OEXCL/createnew. Between the unlink and the recreate, a local attacker with write access to the destination directory can drop in a symlink and redirect the write. Impact:...

ln: rejects non-UTF-8 source filenames in target-directory mode

In target-directory forms ln SOURCE... DIRECTORY, ln rejects source paths with non-UTF-8 filename bytes, while GNU accepts them. Breaks GNU compatibility for byte-oriented filenames on Unix filesystems. PoC: name=$printf 'bad\377'; mkdir dst; : "$name"; ln "$name" dst GNU: exit 0, creates...

comm: lossy UTF-8 conversion silently corrupts non-UTF-8 output

The comm utility in uutils coreutils silently corrupts data by performing lossy UTF-8 conversion on all output lines. The implementation uses String::fromutf8lossy, which replaces invalid UTF-8 byte sequences with the Unicode replacement character U+FFFD. This behavior differs from GNU comm, whic...

mktemp: empty TMPDIR creates temp files in CWD instead of /tmp

The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the...

chmod: recursive mode returns exit code 0 even when some files fail (last-file-wins)

In Chmoder::chmod the recursive branch overwrites the running result instead of accumulating it, so the exit code reflects only the last file processed: if self.recursive r = self.walkdirwithcontextfile, true; // overwrites r else r = self.chmodfilefile.andr; PoC: GNU returns 1 when a file fails;...

chmod: --preserve-root bypassed by any path that resolves to root (e.g. /../)

Chmoder::chmod only compares the literal argument against Path::new"/", so the --preserve-root guard is bypassed by any path that resolves to root — a symlink to / or simply /../. if self.recursive && self.preserveroot && file == Path::new"/" return ErrChmodError::PreserveRoot"/".tostring.into; P...
