PYSEC-2026-2743 Open WebUI: SSRF Protection Bypass in Playwright Web Loader via HTTP Redirects

Summary The SafePlaywrightURLLoader implements a validateurl function to prevent SSRF attacks by checking the IP address of the user-provided URL. However, this validation is performed only on the initial URL. Since Playwright automatically follows HTTP redirects 301/302 by default, an attacker c...

PYSEC-2026-2427 compliance-trestle Vulnerable to SSRF in Remote Fetching Subsystem

A source code audit led to the discovery of three significant security vulnerabilities in the trestle/core/remote/cache.py module. Finding 1 Critical: SSRF CWE-918 The HTTPSFetcher.dofetch method passes a user-supplied URL directly to requests.get without validation. This allows an attacker to...

PYSEC-2026-2982 Pydantic AI: SSRF cloud-metadata blocklist bypass via IPv4-mapped IPv6 (Incomplete fix of CVE-2026-25580)

Summary When an application using Pydantic AI opts a URL into forcedownload='allow-local' which disables the default block on private/internal IPs, the cloud-metadata blocklist could be bypassed by encoding the metadata IP in an IPv6 transition form IPv4-mapped IPv6, 6to4, or NAT64. Dual-stack an...
