Technical details
This is a stored cross-site scripting (XSS) vulnerability in the Debug plugin's CSV serialization rendering. The root cause is the interpolation of user-controlled table cell values directly into the DOM via innerHTML without HTML entity encoding or sanitization. Attackers can craft table rows containing HTML/JavaScript payloads that bypass RFC 4180 CSV quoting rules, since angle brackets and event handler attributes are never escaped. The attack vector is network-based and requires the ability to write a row of data to a table, but does not require authentication or direct server access in chained exploitation scenarios. Once injected, malicious scripts execute with the privileges of the embedding page's origin. A patch has not been mentioned in available sources.
