CVE-2026-3107

Multiple vulnerabilities in Teampass

Published Mar 31, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
Description
Stored Cross-Site Scripting (XSS) in Teampass versions prior to 3.1.5.16, affecting the password manager's password import functionality at the endpoint 'redacted/index.php?page=items'. The application fails to properly sanitize and encode user-input data during the import process, allowing malicious JavaScript payloads to be persistently stored in the database. When other users view the imported passwords, the payload is automatically executed in their browsers, resulting in a stored XSS condition at the endpoint 'redacted/index.php?page=items'. Exploiting this vulnerability allows an attacker to execute arbitrary JavaScript code in the context of multiple users and the administrator, which can lead to session hijacking, credential theft, privilege abuse, and compromise of application integrity.
