Name of the Vulnerable Software and Affected Versions parisneo/lollms (affected versions not specified)

Description A stored cross-site scripting (XSS) issue exists in the POST /api/prompts/share endpoint. The system stores the prompt content variable into DBDirectMessage.content without server-side sanitization. When a user opens a direct message thread, the MessageContentRenderer function uses v-html to insert HTML into the DOM. Because the regex-based frontend sanitizer is insufficient, malicious payloads can execute in the browser. This allows an authenticated user to send a malicious message to another user, leading to arbitrary JavaScript execution, unauthorized actions, exposure of application data, and potential account takeover.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. Restrict the use of the prompt content parameter in the POST /api/prompts/share endpoint to minimize the risk of exploitation.
