{"id":"PYSEC-2025-178","details":"OpenCTI is an open-source cyber threat intelligence platform. In versions starting from 6.4.8 to before 6.4.10, the allow/deny lists can be bypassed, allowing a user to change attributes that are intended to be unmodifiable by the user. It is possible to toggle the `external` flag on/off and change the own token value for a user. It is also possible to edit attributes that are not in the allow list, such as `otp_qr` and `otp_activated`. If external users exist in the OpenCTI setup and the information about these users identities is sensitive, the above vulnerabilities can be used to enumerate existing user accounts as a standard low privileged user. This issue has been patched in version 6.4.10.","aliases":["CVE-2025-24887","GHSA-8262-pw2q-5qc3"],"modified":"2026-05-20T09:19:14.163895Z","published":"2025-04-30T19:15:55.070Z","references":[{"type":"ADVISORY","url":"https://github.com/OpenCTI-Platform/opencti/security/advisories/GHSA-8262-pw2q-5qc3"}],"affected":[{"package":{"name":"pycti","ecosystem":"PyPI","purl":"pkg:pypi/pycti"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.4.9"},{"fixed":"6.4.11"}]}],"versions":["6.4.10","6.4.9"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/pycti/PYSEC-2025-178.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"}]}
