CVE-2026-71210 mealie - DNS-Rebinding TOCTOU in SSRF Guard Allows Internal Network and Cloud Metadata Access

Mealie's AsyncSafeTransport SSRF guard mealie/pkgs/safehttp/transport.py resolves a target hostname once, checks the resolved IP against private-range rules, but then issues the actual outbound HTTP request using the original hostname, which the underlying async transport re-resolves independentl...

CVE-2026-54729

DSSRF is a Node.js library that provides a wide range of utilities and advanced SSRF defense checks. Prior to 1.0.5, isurlsafe can treat localhost as safe when DNS resolver 1.1.1.1 returns NXDOMAIN because dns.resolve4 yields no address and no dns.lookup fallback occurs, allowing server-side...

Potential DoS via the Tudoor mechanism in eventlet and dnspython

eventlet before 0.35.2, as used in dnspython before 2.6.0, allows remote attackers to interfere with DNS name resolution by quickly sending an invalid packet from the expected IP address and source port, aka a "TuDoor" attack. In other words, dnspython does not have the preferred behavior in whic...
