CVE-2024-10955 Information

Description

A Regular Expression Denial of Service (ReDoS) vulnerability exists in gaizhenbiao/chuanhuchatgpt as of commit 20b2e02. The server uses the regex pattern r'<[^>]+>' to parse user input. In Python’s default regex engine this pattern can take polynomial time to match certain crafted inputs. An attacker can exploit this by uploading a malicious JSON payload causing the server to consume 100% CPU for an extended period. This can lead to a Denial of Service (DoS) condition potentially affecting the entire server.
