Authenticated server hang via user-controlled regex execution
Published Mar 20, 2025 · Updated Oct 15, 2025
Regular expression denial of service in GPT Academic as of commit 310122f allows remote authenticated users to hang the server. The 解析项目源码（手动指定和筛选源码文件类型） function passes a user-supplied pattern and search string to Python's regular expression engine, where exponential backtracking can consume CPU indefinitely. Reachability requires low-privileged access to the plugin and control of both inputs; the bounded consequence is a server hang rather than data disclosure or modification.
