Low risk8th percentile - higher than 8% of all known CVEs
Summary
The BetterDocs WordPress plugin before version 4.5.5 does not sanitize an AI-generated documentation summary before storing and outputting it. The feature is exposed to unauthenticated users, allowing them to store a malicious payload via prompt injection that executes in the browser of any visitor, including administrators.
Risk Assessment
An attacker can inject malicious JavaScript that executes in the browsers of administrators and other users, leading to session theft, account takeover, or further compromise of the site.
Recommendation
Immediately update the BetterDocs plugin to version 4.5.5 or later. Restrict access to the AI summary generation feature to authenticated users only.
