What is CVE-2024-8736?
CVE-2024-8736 is a high-severity denial of service vulnerability in parisneo/lollms-webui, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
A Denial of Service (DoS) vulnerability exists in multiple file upload endpoints of parisneo/lollms-webui version V12 (Strawberry). The vulnerability can be exploited remotely via Cross-Site Request Forgery (CSRF). Despite CSRF protection preventing file uploads, the application still processes multipart boundaries, leading to resource exhaustion. By appending additional characters to the multipart boundary, an attacker can cause the server to parse each byte of the boundary, ultimately leading to service unavailability. This vulnerability is present in the `/upload_avatar`, `/upload_app`, and `/upload_logo` endpoints.
