curl: Trailing-dot IPv4 URL bypasses IP-address guard, allows wildcard DNS SAN match

Hi all, Sorry to ruin anybody's day, but we've discovered another issue when it comes to dots. We've found a TLS certificate verification bypass that lets a trailing-dot IPv4 URL -- https://127.0.0.1./ -- pass peer authentication against a wildcard DNS SAN certificate such as DNS:.0.0.1. The IP...

curl: HSTS multi-trailing-dot bypass-ish: possible incomplete fix for CVE-2022-30115

Hi all, Honestly, I'm not completely certain about this issue, but I think the CVE-2022-30115 fix "HSTS bypass via trailing dot" is incomplete: the same asymmetry exists for hostnames with two or more trailing dots, so http://example.com../ still gets sent in plaintext when there's a valid HSTS...

CVE-2026-42345 FastGPT: Cloud metadata endpoint SSRF protection bypass via port specification, IPv6 mapping, hex/decimal IP encoding, and trailing dot

FastGPT is an AI Agent building platform. In versions 4.14.11 and prior, FastGPT's isInternalAddress function in packages/service/common/system/utils.ts blocks cloud metadata endpoints using a fullUrl.startsWith check against a hardcoded list. This check can be bypassed using at least 7 different...

CVE-2026-42345

FastGPT (version 4.14.11 and earlier) exposes an SSRF risk in isInternalAddress() (packages/service/common/system/utils.ts) where a fullUrl.startsWith() hardcoded blocklist can be bypassed by at least 7 URL-encoding techniques that resolve to the cloud metadata endpoint. The broader private IP ch...

GHSA-V8VW-GW5J-W7M6 MCP Registry has open redirect via protocol-relative path in trailing-slash middleware

Summary The TrailingSlashMiddleware in internal/api/server.go is vulnerable to an open redirect attack. An attacker can craft a URL with a protocol-relative path e.g., //evil.com/ that, after trailing slash removal, results in a Location header of //evil.com — which browsers interpret as an...
