{"id":"CVE-2024-6038","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.","modified":"2026-04-10T05:19:15.009838Z","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":[{"ranges":[{"type":"GIT","repo":"https://github.com/gaizhenbiao/chuanhuchatgpt","events":[{"introduced":"0"},{"last_affected":"c7592900ac7a785169c3db12e60c2654446642ec"},{"fixed":"fcdd5fd6b05ef537a1db185ab115758d87e1ba3f"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"20240410"}]}}],"versions":["20230303","20230305","20230317","20230320","20230323","20230327","20230330","20230409","20230413","20230417","20230422","20230427","20230502","20230507","20230513","20230526","20230601","20230614","20230619","20230628","20230709","20230719","20230728","20230809","20230820","20230830","20230911","20230916","20230926","20231006","20231020","20231110","20231215","20231223","20240121","20240305","20240310","20240410","20240628","20240802","20240914"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-6038.json"}}],"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"}]}
