CVE-2026-27192

Feathersjs vulnerability CVE-2026-27192 affects 5.0.39 and earlier. The origin validation in getAllowedOrigin() uses startsWith() to compare Referer against allowed origins, which can be bypassed by registering a domain with a shared prefix (e.g., https://target.com.attacker.com vs https://target...

kernel: smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match()

A flaw was found in the Linux kernel’s SMC Shared Memory Communication module: in smcclcprfxmatch, the function is called from smclistenwork without proper RCU or RTNL protection. The code previously used skdstgetsk-dev, which can lead to a use-after-free UAF condition if the sk’s destination is...

CVE-2026-24904

TrustTunnel is an open-source VPN protocol with a rule bypass issue in versions prior to 0.9.115. In tlslistener.rs, TlsListener::listen peeks 1024 bytes and calls extractclientrandom.... If parsetlsplaintext fails for example, a fragmented/partial ClientHello split across TCP writes,...

@fastify/middie security vulnerabilities

@fastify/middie is an open-source middleware engine developed by Fastify. Versions of @fastify/middie prior to 9.1.0 contained security vulnerabilities. These vulnerabilities were due to improper path prefix matching, which could allow the middleware to bypass security checks...

Path Traversal

@anthropic-ai/claude-code is vulnerable to Path Traversal. The vulnerability is due to using prefix matching instead of canonical path comparison, which allows bypassing directory restrictions and accessing files outside the CWD if a directory with the same prefix exists and untrusted content is...

CVE-2025-54387 IPX is Vulnerable to Path Traversal via Prefix Matching Bypass

IPX is an image optimizer powered by sharp and svgo. In versions 1.3.1 and below, 2.0.0-0 through 2.1.0, and 3.0.0 through 3.1.0, the approach used to check whether a path is within allowed directories is vulnerable to path prefix bypass when the allowed directories do not end with a path...

CVE-2025-54387

IPX is an image optimizer (UnJS) vulnerable to a path-prefix bypass in its directory-check logic. Affected versions: 1.3.1 and earlier; 2.0.0-0 to 2.1.0; 3.0.0 to 3.1.0. The vulnerability allows bypassing allowed-directory checks via raw prefix comparison, potentially enabling access to files out...

IPX Allows Path Traversal via Prefix Matching Bypass

Summary The approach used to check whether a path is within allowed directories is vulnerable to path prefix bypass when the allowed directories do not end with a path separator. This occurs because the check relies on a raw string prefix comparison. PoC - setup mkdir /public123 move a png file...
