What happened
The Text Styler WordPress plugin through 1.1.1 does not sanitise and escape user-supplied styling values before outputting them within a front-end style block, and does not verify that a user may edit the target post, allowing users with contributor-level access or above to store JavaScript that executes in the browser of anyone viewing the affected post, including administrators.
Affected versions
Text Styler: 0 through 1.1.1 (semver) Fixed: See vendor advisory.
