CVE-2026-97723 Details
Description
madpsy ka9q_ubersdr before 0.1.58 has a stored cross-site scripting (XSS) vulnerability in the chat message rendering functionality. User-controlled URLs in chat messages were insufficiently neutralized before being converted into HTML links. Quotation characters could break out of the generated href attribute and introduce attacker-controlled HTML attributes, allowing arbitrary JavaScript to execute in the browser of another user when the stored chat message was rendered. No click on the malicious link was required.
A stored cross-site scripting vulnerability has been identified in madpsy ka9q_ubersdr versions prior to 0.1.58. The issue arises in the chat message rendering feature, where user-controlled URLs in chat messages were not properly sanitized before being converted into HTML links. This lack of adequate sanitization allowed quotation marks to escape the href attribute, enabling the introduction of attacker-controlled HTML attributes. As a result, arbitrary JavaScript could be executed in the browser of another user when the stored chat message was displayed. Notably, no interaction with the malicious link was necessary for the exploitation to occur.
Users can update to madpsy ka9q_ubersdr version 0.1.58 or later, where this vulnerability has been fixed.
