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...

curl: Cookie attribute TAB injection regression in Set-Cookie parsing

Overview | | | |---|---| | Component | lib/cookie.c — parsecookieheader | | Type | Security regression incomplete input validation | | CWE | CWE-20 Improper Input Validation | | Severity | LOW CVSS 3.1 estimated 3.7, comparable to CVE-2022-35252 | | Affected | curl 8.18.0 through current HEAD | |...

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...

curl: Bypassing Strict SSH Server Verification via Connection Pool Reuse in libcurl

Summary There is a logic flaw in how libcurl manages its connection pool for SSH protocols SFTP/SCP. When evaluating an existing connection for reuse, sshconfigmatches in lib/url.c fails to compare server identity verification policies. By ignoring CURLOPTSSHKNOWNHOSTS, CURLOPTSSHHOSTPUBLICKEYMD5...

curl: Use-After-Free race condition in url_move_hostname() via shared connection pool

Summary: In lib/url.c, urlconnreuseadjust calls urlmovehostname which frees conn-host.rawalloc and conn-host.encalloc via Curlsafefree and Curlfreeidnconvertedhostname after Curlcpoolfind has already released the connection pool lock. A second thread doing a concurrent pool lookup still holds tha...

AWS VDP: OS Command Injection in `aws-cdk-lib` NodejsFunction via Unsanitized `OsCommand` Helper (Supply Chain RCE)

A vulnerability was discovered in the "aws-cdk-lib" NodejsFunction that allowed for OS command injection through the unsanitized "OsCommand" helper. The vulnerability was caused by the lack of proper escaping of user-controlled data when constructing shell commands during Docker-based bundling...

curl: HackerOne Vulnerability Report: libcurl SSL/TLS Identity Leakage via Insecure Connection Reuse

Summary libcurl contains a critical logic flaw in its connection reuse mechanism where transfers using the CURLOPTSSLCTXFUNCTION SSL context callback to establish a specific identity e.g., via client certificates can have their connections incorrectly reused by subsequent, unauthenticated transfe...

curl: HTTP/2 PUSH_PROMISE header loss on OOM bypasses scheme validation (regression of 2e8c922a89)

Summary: In lib/http2.c:1490, when curlmaprintf fails due to memory pressure, the push promise header is silently dropped but the callback returns success. If the lost header is the :scheme pseudo-header, the security check at line 733 that blocks HTTPS pushes over insecure connections is skipped...

arkadiyt-projects: Path Traversal in writeFile via Unsafe Prefix Containment Check Allows Out-of-Directory Writes

A path traversal vulnerability was discovered in the protodump tool. The vulnerability allowed an attacker to influence the output filename construction and bypass the containment check, enabling writes outside the intended output directory. The vulnerability was caused by the use of...

arkadiyt-projects: SSRF Filter Bypass via Unblocked NAT64 Local-Use IPv6 Prefix (64:ff9b:1::/48)

A vulnerability was discovered in the ssrffilter library version 1.3.0. The library failed to block the NAT64 local-use IPv6 prefix 64:ff9b:1::/48, allowing such addresses to be treated as public. This enabled SSRF requests through /fetch to targets encoded under that prefix when routable in the...

This report is not public...

curl: CRLF Injection in HAProxy PROXY Protocol via CURLOPT_HAPROXY_CLIENT_IP allows IP spoofing and protocol injection

Summary: CURLOPTHAPROXYCLIENTIP introduced in curl 8.2.0 accepts arbitrary strings without any validation or sanitization before injecting them into the HAProxy PROXY protocol v1 header. An attacker who can influence the value passed to this option e.g., through a web application that proxies...

AWS VDP: Sandbox User Can Inject Rogue CA Certificate into OS Trust Store via Sudo-Allowed deploy-certificates.sh

A vulnerability was found in the Bedrock AgentCore Code Interpreter sandbox. The sandbox granted a user passwordless sudo access to a script that deployed certificates to the OS trust store. An attacker could have generated a rogue CA certificate, placed it in a writable directory, and then used...

AWS VDP: Bedrock AgentCore Starter Toolkit Creates Gateway IAM Roles Without Confused Deputy Protections

The Bedrock AgentCore Starter Toolkit was found to create IAM roles for the AgentCore Gateway with trust policies that lacked certain condition keys. This enabled a cross-account confused deputy attack where any AgentCore workload in any AWS account could assume the victim's Gateway role. The rol...
