CVE-2023-49471Public exploitNetwork attack vector

Authenticated SSRF via unvalidated image URL

Published Jan 10, 2024 · Updated Jun 3, 2025

Blind SSRF in karlomikus Bar Assistant before 3.2.0 allows remote authenticated users to send server-side requests via image URLs. The /bar/api/images upload endpoint passes images[0][image_url] to Image::make() without validating the destination before fetching it. A valid bearer token is required; the published proof of concept establishes access to attacker-chosen network destinations but does not demonstrate code execution.
