Summary

Drupal Editoria11y Accessibility Checker versions from 0.0.0 before 2.2.23 and from 3.0.0 before 3.0.9 are affected. The flaw is a privilege definition with unsafe actions (CWE-267), which lets a user gain privileges they should not have. An attacker with low privileges and no user interaction can exploit it to gain higher access, with a low impact on integrity. CISA has not added it to KEV, and its SSVC exploitation rating is none.
