Summary

A stored cross-site scripting (XSS) vulnerability in madpsy ka9q_ubersdr before 0.1.58 in the chat message rendering functionality. User-controlled URLs were insufficiently neutralized before being converted into HTML links, and quotation characters could break out of the href attribute and inject arbitrary HTML attributes. This allows arbitrary JavaScript execution in another user's browser without requiring a click.

Risk Assessment

An attacker can execute arbitrary JavaScript in the browsers of other users viewing the chat, potentially leading to session or data theft. No click by the victim is required.

Recommendation

Update ka9q_ubersdr to version 0.1.58 or later. Until updated, consider disabling link rendering in chat messages.
