{"id":"CVE-2024-6038","summary":"ReDoS Vulnerability in gaizhenbiao/chuanhuchatgpt","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":["PYSEC-2024-318"],"modified":"2026-08-12T03:51:14.195914757Z","published":"2024-06-27T18:41:45.405Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/6xxx/CVE-2024-6038.json","cna_assigner":"@huntr_ai","cwe_ids":["CWE-1333"]},"references":[{"type":"WEB","url":"https://huntr.com/bounties/d41cca0a-82bc-4cbf-a52a-928d304fb42d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/6xxx/CVE-2024-6038.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-6038"},{"type":"FIX","url":"https://github.com/gaizhenbiao/chuanhuchatgpt/commit/fcdd5fd6b05ef537a1db185ab115758d87e1ba3f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gaizhenbiao/chuanhuchatgpt","events":[{"introduced":"c7592900ac7a785169c3db12e60c2654446642ec"},{"fixed":"fcdd5fd6b05ef537a1db185ab115758d87e1ba3f"}],"database_specific":{"source":["CPE_STRING","REFERENCES"],"cpe":"cpe:2.3:a:gaizhenbiao:chuanhuchatgpt:20240410:*:*:*:*:*:*:*","extracted_events":[{"introduced":"20240410"},{"last_affected":"20240410"}]}}],"versions":["20240410","20240914","20240802","20240628"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-6038.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
