CVE-2026-97723: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in madpsy ka9q_ubersdr
madpsy ka9q_ubersdr versions before 0.1.58 contain a stored cross-site scripting (XSS) vulnerability in the chat message rendering feature. The vulnerability arises because user-controlled URLs in chat messages are not properly neutralized before being converted into HTML links. This allows an attacker to inject arbitrary JavaScript code that executes in the browsers of other users viewing the stored chat messages, without requiring any user interaction such as clicking a link.
AI Analysis
Technical Summary
CVE-2026-97723 is a stored cross-site scripting vulnerability in madpsy ka9q_ubersdr prior to version 0.1.58. The issue is due to improper neutralization of user-controlled URLs in chat messages before rendering them as HTML links. Specifically, quotation characters in URLs can break out of the href attribute and inject malicious HTML attributes, enabling arbitrary JavaScript execution in other users' browsers when the chat message is rendered. This vulnerability does not require user interaction to trigger the script execution.
Potential Impact
An attacker can execute arbitrary JavaScript in the context of other users' browsers who view the stored chat messages. This can lead to information disclosure or session hijacking. The CVSS 3.1 base score is 5.4 (medium severity) with network attack vector, high attack complexity, no privileges required, no user interaction, and impacts on confidentiality and integrity but not availability.
Mitigation Recommendations
No official patch or fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when interacting with chat messages containing URLs from untrusted sources.
