Summary

A Cross-site Scripting (XSS) vulnerability was identified in the from_dict method of the AppLollmsMessage class in parisneo/lollms prior to version 2.2.0. The vulnerability arises from the lack of sanitization or HTML encoding of the content field when deserializing user-provided data, allowing an attacker to inject malicious HTML or JavaScript payloads executed in another user's browser. Exploitation can lead to account takeover, session hijacking, or wormable attacks.

Risk Assessment

XSS may lead to account and session takeover for users and to wormable propagation among application users.

Recommendation

Update lollms to version 2.2.0 or later and implement sanitization and HTML encoding of input data.
