{"id":"PYSEC-2024-318","details":"A Regular Expression Denial of Service (ReDoS) vulnerability exists in the latest version of gaizhenbiao/chuanhuchatgpt. The vulnerability is located in the filter_history function within the utils.py module. This function takes a user-provided keyword and attempts to match it against chat history filenames using a regular expression search. Due to the lack of sanitization or validation of the keyword parameter, an attacker can inject a specially crafted regular expression, leading to a denial of service condition. This can cause severe degradation of service performance and potential system unavailability.","aliases":["CVE-2024-6038"],"modified":"2026-07-13T07:15:21.472155089Z","published":"2024-06-27T19:15:19.040Z","references":[{"type":"FIX","url":"https://github.com/gaizhenbiao/chuanhuchatgpt/commit/fcdd5fd6b05ef537a1db185ab115758d87e1ba3f"},{"type":"EVIDENCE","url":"https://huntr.com/bounties/d41cca0a-82bc-4cbf-a52a-928d304fb42d"}],"affected":[{"package":{"name":"chuanhuchatgpt","ecosystem":"PyPI","purl":"pkg:pypi/chuanhuchatgpt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"20240410"}]}],"versions":["3.2.5"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/chuanhuchatgpt/PYSEC-2024-318.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
