CVE-2024-4499Public exploitNetwork attack vector

Unauthorized XTTS API actions via lax CORS

Published Jun 24, 2024 · Updated Aug 1, 2024

Cross-site request forgery in ParisNeo LoLLMS 9.6 XTTS server allows remote attackers to read and write audio files through crafted webpages. The server's lax CORS policy accepts cross-origin browser requests and permits arbitrary LoLLMS-XTTS API calls from an attacker-controlled origin. No authentication is required, but a user must visit attacker-controlled content; broader filesystem access requires chaining with other flaws.
