National Vulnerability Database Information

Description: 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.

FIRST Information

EPSS Score: N/A

The EPSS (Exploit Prediction Scoring System) is a score from 0 to 1 that indicates the probability that a vulnerability will be exploited in the real world in the next 30 days. A higher value indicates a greater likelihood of exploitation.

EPSS Score not available for this CVE.

Percentile: N/A

The Percentile indicates how much higher this vulnerability's EPSS score is compared to all other vulnerabilities in the EPSS database. For example, a percentile of 0.90 (90%) means that 90% of vulnerabilities have an EPSS score equal to or lower than the current one.

Percentile not available for this CVE.
