CVE-2025-25301Public exploitNetwork attack vector

Internal image disclosure via unvalidated URL fetch

Published Mar 3, 2025 · Updated Mar 3, 2025

SSRF in the rembg HTTP server 2.0.57 and earlier allows remote attackers to read internal images through the /api/remove URL parameter. The endpoint passes the caller-supplied URL directly to aiohttp ClientSession.get without validating its destination. The HTTP server must be running and reachable; successful requests disclose images accessible from its internal network.
