Gotenberg <= 8.30.1 - Server Side Request Forgery

Gotenberg is an API-based document conversion tool. In versions 8.30.1 and earlier, the default private-IP deny-lists for the --webhook-deny-list and --api-download-from-deny-list flags use a case-sensitive regular expression ^https?:// to match URL schemes. Because Go's net/url.Parse normalizes...

CVE-2026-69257 Flowise: SSRF Protection Bypass via IPv4-Mapped IPv6 Addresses

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, Flowise's HTTP security module httpSecurity.ts did not normalize IPv4-mapped IPv6 addresses such as ::ffff:127.0.0.1 and ::ffff:169.254.169.254 before checking them against the deny list...

CVE-2026-69257

Flowise prior to v3.1.3 had an SSRF protection bypass in its HTTP security module due to improper handling of IPv4-mapped IPv6 addresses (::ffff:127.0.0.1, ::ffff:169.254.169.254). ipaddr.js categorizes these as IPv6, so IPv4 CIDR deny-list checks were skipped in isDeniedIP(), allowing requests f...

GHSA-J99Q-93C9-H869 MCPVault: PathFilter restricted-directory deny-list bypass via case and trailing dot/space equivalence

On case-insensitive filesystems macOS, Windows, PathFilter compiled its deny-list patterns case-sensitively and matched the path verbatim, so names like .Git/config, .GIT/config, or .oBsIdIaN/secrets.md slipped past the .git/.obsidian/nodemodules restriction while the OS opened the real file. On...
