JLSEC-2026-1164 Deno: `fetch()` API sandbox bypass via missing DNS resolution check

Summary When fetch was called, Deno checked the destination hostname against --deny-net rules but did not re-check the IP addresses that hostname resolved to. An attacker-controlled script could use a specially crafted domain name that passes the hostname check yet resolves to a denied IP,...

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-2026-54020

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.11.0, Open WebUI resolved a hostname during URL validation and rejected private, loopback, and link-local addresses, but the HTTP clients resolved the hostname again at connection time. An authenticat...

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...

SUSE CVE-2026-34984

External Secrets Operator reads information from a third-party service and automatically injects the values as Kubernetes Secrets. Versions 2.2.0 and below contain a vulnerability in runtime/template/v2/template.go where the v2 template engine removes env and expandenv from Sprig's TxtFuncMap but...

SUSE CVE-2026-42592

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, FilterOutboundURL resolves the hostname, checks the resolved IPs against the private-address deny-list, and returns only the error. It discards the resolved addresses. Chromium later performs its own DNS resolution when i...

CVE-2026-44507

Rsync is a file-copying tool that uses a delta-transfer algorithm to synchronize remote and local files. In versions prior to 3.4.3, when using a daemon configured with a chroot, the reverse DNS lookup of the connecting client was performed after the chroot had been entered. If the chroot did not...

CVE-2025-71390

SurrealDB before 2.2.6, 2.3.6, and 2.1.8 and 3.0.0-alpha.7 and earlier fails to validate DNS-resolved hostnames against --deny-net network access restrictions in its http:: functions. An authenticated user can invoke http:: with a hostname that resolves to a denied IP address, causing the server ...

CVE-2026-63306 stoatchat before 0.13.5 Unauthenticated SSRF via proxy and embed endpoints

stoatchat before 0.13.5 contains an unauthenticated server-side request forgery vulnerability in the /proxy and /embed endpoints that accept arbitrary URLs without DNS resolution filtering or private IP range validation. Attackers can enumerate internal services, fingerprint applications, and rea...

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...
