The BetterDocs WordPress plugin before 4.5.5 does not sanitise an AI-generated documentation summary before storing and outputting it, and the feature that generates it is exposed to unauthenticated users, allowing them to store a malicious payload via prompt injection that executes in the browser of any visitor who views the affected page, including administrators.
