CVE-2025-27822
Backdrop CMS Masquerade Module Privilege Escalation Vulnerability
Description
An issue was discovered in the Masquerade module before 1.x-1.0.1 for Backdrop CMS. It allows people to temporarily switch to another user account. The module provides a "Masquerade as admin" permission to restrict people (who can masquerade) from switching to an account with administrative privileges. This permission is not always honored and may allow non-administrative users to masquerade as an administrator. This vulnerability is mitigated by the fact that an attacker must have a role with the "Masquerade as user" permission.
