Summary
CVE-2026-84699 is an authentication bypass vulnerability in Team Password Manager, a self-hosted password management platform for teams. The application fails to enforce authentication requirements in the local account password reset flow, allowing an unauthenticated, remote attacker to reset the password of a local account and log in as that user. The issue carries a CVSS v3.1 base score of 9.1 (Critical) and a CVSS v4.0 score of 9.3, and affects Team Password Manager before version 14.184.308.
Technical details
- Root cause: The password reset flow for local accounts does not properly enforce authentication requirements, classified as CWE-640 (Weak Password Recovery Mechanism for Forgotten Password).
- Trigger conditions: An attacker sends requests to the exposed password reset functionality without needing valid credentials, a session, or user interaction.
- Attack vector: Network-based, low complexity, no privileges or user interaction required (AV:N/AC:L/PR:N/UI:N).
- Impact: Successful exploitation allows an unauthenticated attacker to reset a local account’s password and authenticate as that user, resulting in high confidentiality and integrity impact — full unauthorized access to stored passwords and shared credentials managed by the application.
Affected software
- Team Password Manager: all versions before 14.184.308
Severity
- CVSS v3.1 Base Score: 9.1 (Critical) —
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N - CVSS v4.0 Score: 9.3 (Critical) —
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
Mitigation and recommended actions
- Immediate: Upgrade Team Password Manager to version 14.184.308 or later, where the vendor has fixed the password reset functionality.
- If patching is not immediately possible: Restrict network access to the Team Password Manager instance (e.g., place it behind a VPN or IP allowlist) so the password reset endpoint is not reachable by unauthenticated external parties, and monitor for unexpected password reset activity on local accounts until the upgrade can be applied.
