CVE-2024-8026Public exploitNetwork attack vector

Data alteration via unrestricted cross-origin requests

Published Mar 20, 2025 · Updated Mar 20, 2025

CSRF in the QAnything backend API as of commit d9ab8bc allows remote attackers to alter or delete knowledge-base data via cross-origin requests. The backend sets overly permissive CORS headers that accept every origin across all API endpoints, so a hostile site can issue browser-mediated calls. A user must visit attacker-controlled content; resulting requests can create, upload, list, or delete files and manage knowledge bases with that user's access.
