CVE-2026-100176 · Severity: info · Published 2026-09-25

AIL Framework is an open-source tool analysts use to search and archive web data. The tool has a feature that displays usernames imported from chats and forums on a visual timeline. An attacker can inject malicious code into a username, which executes when an authenticated analyst hovers over that timeline entry, potentially allowing the attacker to steal the analyst's session credentials or perform actions on their behalf.

## Technical details

Stored XSS in the client-side JavaScript timeline tooltip (var/www/static/js/d3/timeline_basic.js) where usernames are rendered into the DOM using D3's html() method without HTML sanitization. An attacker must first inject a crafted username (containing HTML event handlers like onerror attributes) into the application's data store via chat imports or forum crawling, then the victim analyst must view and hover over the username timeline entry. Successful exploitation allows arbitrary JavaScript execution in the authenticated analyst's browser context.
