Name of the Vulnerable Software and Affected Versions
Broken Link Checker versions prior to 2.4.12

On sites using plain permalinks, the plugin fails to limit the query variables accepted from user input. This allows unauthenticated users to overwrite arbitrary PHP global variables and execute arbitrary code on the server when a classic (non-block) editor is active.
