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. 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: {} references: - type: FIX url: https://github.com/gaizhenbiao/chuanhuchatgpt/commit/fcdd5fd6b05ef537a1db185ab115758d87e1ba3f - type: EVIDENCE url: https://huntr.com/bounties/d41cca0a-82bc-4cbf-a52a-928d304fb42d severity: - type: CVSS_V3 score: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
