DescriptionCVE.org

Pimcore is an Open Source Data & Experience Management Platform. Prior to 2025.4.6 and 2026.1.6, an unauthenticated attacker who knows a valid admin username can take over any Pimcore admin account by sending a password reset request with an attacker-controlled resetPasswordUrl. The server generates a real cryptographic recovery token, appends it to the supplied URL, and emails the link to the victim; when the victim clicks the link, the token is sent to the attacker and can be used with POST /pimcore-studio/api/login/token to authenticate with full admin privileges while bypassing two-factor authentication. This issue is fixed in versions 2025.4.6 and 2026.1.6.

AnalysisAI

Full admin account takeover in Pimcore (Studio backend) before 2025.4.6 and 2026.1.6 lets an unauthenticated attacker who knows a valid admin username hijack that account by submitting a password-reset request with an attacker-controlled resetPasswordUrl; the server appends a genuine recovery token to that URL and emails it to the victim, so a single victim click leaks the token to the attacker, who authenticates via POST /pimcore-studio/api/login/token with full admin rights and bypasses 2FA. GitHub advisory GHSA-h854-c3m3-mh5v classifies this as an authentication bypass (CWE-640). …
