What is CVE-2025-27822?
CVE-2025-27822 is a high-severity vulnerability in backdropcms Masquerade, published on 7 Mar 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
