Summary

The Envira Gallery WordPress plugin before 1.16.2 does not check authorization correctly in its gallery conversion feature (CWE-862). It checks whether the requester can edit an arbitrary post they name, not whether they may create gallery content. This lets users with contributor-level access create and publish gallery posts that the plugin settings otherwise withhold from them. The references include a link to an exploit.

Description from the CNA

The Envira Gallery WordPress plugin before 1.16.2 does not correctly check authorization on its gallery-conversion feature, verifying that the requester can edit an arbitrary post they name rather than that they are allowed to create the Envira Gallery WordPress plugin before 1.16.2's own gallery content, allowing users with contributor-level access to create and publish gallery posts that the Envira Gallery WordPress plugin before 1.16.2's settings otherwise withhold from them.
