This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 88% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

grav-plugin-admin is an HTML user interface that provides a way to configure Grav and create and modify pages. In 1.10.52 and earlier, an authenticated attacker with admin.users permission can change the password of any user account, including the super administrator, by sending a direct POST request to /admin/user/{username}?task=save with data[password] because saveUser authorizes the caller's user-management permission but does not verify whether the caller may edit the target user. This issue is expected to be fixed in version 1.10.53.
