CVE-2024-9229: Quivr unauthenticated Denial of Service (DoS) via Multipart Boundary

March 20, 2025 (updated March 21, 2025)

A Denial of Service (DoS) vulnerability in the file upload feature of stangirard/quivr v0.0.298 allows unauthenticated attackers to cause excessive resource consumption by appending characters to the end of a multipart boundary in an HTTP request. This leads to the server continuously processing each character, rendering the service unavailable and impacting all users.
