The vulnerability arises because the username is provided via an HTTP request from the client side, rather than being read from a secure source like a cookie. This allows an attacker to pass another user's username to the get_model function, thereby gaining unauthorized access to that user's chat history.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-304"],"references":["https://huntr.com/bounties/21e54c3f-e2d7-423b-9890-1f0cb99af4dd"],"products":["gaizhenbiao:chuanhuchatgpt"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2024-9216","score":0.00628,"percentile":0.50134,"date":"2026-10-31"},"kev":null,"osv":[{"id":"PYSEC-2025-97","url":"https://osv.dev/vulnerability/PYSEC-2025-97","summary":"","modified":"2026-05-21T15:00:08.151294348Z","packages":[{"ecosystem":"PyPI","name":"chuanhuchatgpt","purl":"pkg:pypi/chuanhuchatgpt","ranges":["<=2024-12-04"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
