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...
