Incomplete Fix for CVE-2026-0848: 5 Stanford Interface Classes Still Vulnerable to Untrusted JAR Code Execution

Description CVE-2026-0848 fixed untrusted JAR code execution in StanfordSegmenter by adding SHA256 verification in PR 3477. However, the fix was ONLY applied to nltk/tokenize/stanfordsegmenter.py. Five other Stanford interface classes have the identical vulnerability — they accept user-controllab...

Lambda Layer `safe_mode=None` Guard Bypass — Arbitrary Code Execution via `from_config()`

Description Keras's Lambda layer deserializes Python functions using marshal.loads on attacker-controlled bytecode. A safe-mode guard in raiseforlambdadeserialization is intended to block this path, but a logic error causes the guard to silently pass when safemode is None — the default value when...

Node.js: Improper Input Validation — HTTP Response Parser Unconditionally Accepts Bare CR in Status Line

The llhttp HTTP response parser in Node.js up to version 24.14.1 llhttp v9.3.0 and v9.3.1 was found to unconditionally accept a bare carriage return CR as a valid response status line terminator. This parsing asymmetry was present in the response path but not in the request parsing, enabling...

curl: Internal application wrapper or script using curl

While -guid is not a standard or documented curl command, a Command Injection or Argument Injection vulnerability within a specific application that wraps curl. Security Analysis: curl -guid -url example.com 1. Status of the "-guid" FlagUndocumented/Non-existent: The official curl binary does not...

curl: ignoring 'options' when doing connection reuse

libcurl contains a significant logic flaw in its connection pool matching mechanism. When a transfer specifies a required authentication policy—such as a specific SASL mechanism e.g., ;AUTH=GSSAPI or a restricted set of SSH authentication types CURLOPTSSHAUTHTYPES—libcurl fails to verify these...

Authorization bypass on all trace endpoints when auth is enabled

Description When MLflow runs with auth enabled, the trace API endpoints don't have authorization validators registered. The beforerequest handler checks each request against BEFOREREQUESTHANDLERS — experiments, runs, models all have entries there, but traces have zero entries. When no validator i...

curl: Negotiate connection reuse with wrong credentials when using CURLAUTH_ANY

Summary: CVE-2026-1965 fixed connection reuse for Negotiate authentication by adding urlmatchauthnego in urlmatchconn at line 1244 of lib/url.c. When a first handle authenticates via Negotiate Kerberos on a connection and that connection returns to the pool, a second handle with different...

curl: # SCURLOPT_SSH_KNOWNHOSTS and host fingerprint pins are silently bypassed when an SSH connection is reused from the connection pool

Product libcurl all versions, all platforms, compiled with USESSH Protocols affected: sftp://, scp:// --- Summary libcurl's connection pool reuse logic for SSH-based protocols SFTP, SCP contains a security gap that allows a transfer's server-verification policy to be completely ignored. When an...

curl: Data race in Curl_dnscache_add_negative() corrupts shared DNS cache — heap corruption and double-free when using CURLOPT_SHARE with CURL_LOCK_DATA_DNS

Data race in Curldnscacheaddnegative corrupts shared DNS cache — heap corruption and double-free when using CURLOPTSHARE with CURLLOCKDATADNS Severity: Medium CVSS 3.1: 6.5 — AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H --- Summary Curldnscacheaddnegative in lib/dnscache.c modifies the shared DNS cache ha...

[CWE-73] Keras — Arbitrary HDF5 File Read via Virtual Dataset Bypass of External Storage Check (CVE-2026-1669 Incomplete Fix)

Description The fix for CVE-2026-1669 in Keras's H5IOStore.verifydataset method savinglib.py:1051 is incomplete. The patch checks dataset.external to block HDF5 datasets that use external file storage, but it does not check dataset.isvirtual. HDF5 Virtual Datasets VDS — created via...

Zip Slip Arbitrary File Write via ZipFile.extractall() in StorageManager

Description The ClearML SDK uses ZipFile.extractall without path traversal validation when extracting .zip archives in StorageManager.extracttocache storage/manager.py line 199. In contrast, .tar.gz and .tgz archives ARE protected using a safeextract function storage/util.py line 414 that validat...

Tucows (VDP): Stored XSS in nameserver field on account settings page

A stored XSS vulnerability was discovered in the nameserver field on the account settings page. The lack of input validation and weak CSP configuration allowed the injection of malicious JavaScript code that executed when the settings page was reloaded. The vulnerability was limited to a self-XSS...

arkadiyt-projects: Authorization header leak in ssrf_filter via cross-host redirect leads to credential theft and unauthorized access

A vulnerability was discovered in the ssrffilter library. The vulnerability allowed an attacker-controlled redirect target to receive credentials that were intended only for the original request origin. This was possible because ssrffilter followed redirects by rebuilding each redirected request...

curl: CVE-2026-5545: wrong reuse of HTTP Negotiate connection

Summary: An attacker sharing a libcurl multi-handle connection pool can hijack another user's Negotiate/Kerberos-authenticated connection. When User A authenticates via Negotiate SPNEGO and the connection returns to the pool, User B using CURLAUTHANY with different credentials gets that connectio...

GitHub: GitHub user to server tokens can create issues in any public repository

A vulnerability was identified in GitHub Enterprise Server that allowed a user-to-server token scoped to a GitHub App installation to perform certain write operations on public repositories outside the token's intended scope. The authorization check only verified that the installation had read...

Arbitrary File Read via Percent-Encoded Path Traversal in nltk.data.find() / nltk.data.load() - Incomplete Fix of Issue #3504

The security fix for path traversal PR 3522, pathsec module that was merged into NLTK 3.9.3 to address GitHub Issue 3504 is incomplete. The UNSAFENOPROTOCOLRE regex in data.py:57 checks for literal ../ but url2pathname on line 653 decodes percent-encoded sequences after the validation, not before...

curl: Missing server identity policy enforcement in SSH connection reuse allows host key verification bypass via pool poisoning

Missing server identity policy enforcement in SSH connection reuse allows host key verification bypass via pool poisoning --- Summary sshconfigmatches in lib/url.c decides whether an existing SSH connection can be reused by a new transfer handle. It checks client key paths rsa, rsapub but never...

GitHub: GitHub scoped user to server tokens can escape their installation

An improper authorization vulnerability in scoped user-to-server ghu token authorization in GitHub Enterprise Server was discovered. The vulnerability allowed an authenticated attacker to access private repositories outside the intended installation scope, which could have included write...
