CVE-2026-56325 Capgo - App ID Confusion via ILIKE Wildcard in Preview Subdomain Lookup

Capgo before 12.128.2 uses ILIKE pattern matching instead of exact matching for appid lookup in the preview subdomain resolver, allowing underscore characters in appid to act as SQL wildcards. Attackers can create apps with appids differing by one character at underscore positions to cause...

Improper Request Routing

http-proxy-middleware is vulnerable to improper request routing. The vulnerability is due to unanchored substring matching in the host+path router selector logic, where configured host+path entries are matched against attacker-controlled request metadata using partial string comparisons instead o...

Name of the Vulnerable Software and Affected Versions Capgo versions prior to 12.128.2 Description The preview subdomain resolver uses ILIKE pattern matching instead of exact matching for app id lookup. This allows underscore characters within the app id to function as SQL wildcards. An attacker...

GHSA-JRPC-7VXP-69P6 http4k: `reverseProxy()` defaulted to substring (`Contains`) matching on `Host`; tightened to `Exact`

Impact reverseProxy and reverseProxyRouting matched configured vhosts by substring on the Host header Contains matcher by default. The intended use of these functions in http4k is outbound dispatch e.g. matching AWS service subdomains, per the Contains docstring and test-time composition of fake...

CVE-2026-48794 Authelia has an Edge Case Access Control Rule Mismatch

Authelia is an open-source authentication and authorization server providing two-factor authentication and single sign-on SSO for applications via a web portal. In versions 4.36.0 through 4.39.19, due to lack of canonicalization of domains in very specific edge cases, an access control rule may b...

GHSA-QW6V-5FCF-5666 Network-AI: Improper Neutralization of Special Elements used in an OS Command

Summary The agent sandbox gates shell commands behind an allowlist SandboxPolicy.isCommandAllowed, which THREATMODEL.md calls the main control against a compromised agent Adversary 3.2. The allowlist glob-matches the whole command string, but ShellExecutor runs that string through /bin/sh -c. So...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel’s implementation of string matching within packets. A privileged user with root or CAPNETADMIN status can insert rules into iptables, and this action may cause the system to panic. The issue affects kernels prior to version 5.5-rc1...

http-proxy-middleware `router` host+path substring matching allows Host-header-driven backend routing bypass

Summary http-proxy-middleware documents router proxy-table entries as host, path, or host+path selectors, but the host+path implementation uses unanchored substring matching on attacker-controlled request metadata. As a result, a crafted Host header that is only a superstring match for a configur...

CVE-2026-11525

The issue affects undici’s cookie parsing in Set-Cookie headers. The root cause is a permissive substring match for the SameSite attribute during parsing, accepting any value containing Strict, Lax, or None instead of enforcing a case-insensitive exact match per RFC 6265. This can cause downstrea...

CVE-2026-11525 undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching

Impact: When undici parses a Set-Cookie header, it accepts any SameSite attribute value that contains Strict, Lax, or None as a substring, rather than the case-insensitive exact match specified by RFC 6265. Non-spec values are silently mapped to one of the three standard tokens. For example,...

GHSA-QRP7-CVWR-J2C6 Caddy: Windows `file_server` path authorization bypass via encoded backslash

Summary On Windows, Caddy path matchers treat /private\secret.txt as outside /private/, but fileserver later resolves the same request path as private\secret.txt on disk. An unauthenticated remote client can request /private%5csecret.txt and bypass Caddy path-scoped auth/deny routes protecting...

Authentication Bypass

@nestjs/platform-fastify is vulnerable to Authentication Bypass. The vulnerability is due to improper route matching between Fastify and NestJS middleware registered through MiddlewareConsumer.forRoutes, which allows an attacker to bypass authentication middleware by appending a trailing slash / ...

GHSA-529G-XQ4F-CW38 @astrojs/netlify broadens Astro image.remotePatterns in Netlify Image CDN config

Summary @astrojs/netlify converts Astro image.remotePatterns into Netlify Image CDN images.remoteimages regular expressions with broader semantics than Astro's canonical matcher. A single wildcard hostname such as .example.com is converted to an optional subdomain regex, so the apex host matches....
