CVE-2026-100172 · Severity: info · Published 2026-09-25

The AIL Framework, an intelligence analysis tool, contains a stored cross-site scripting vulnerability in web interface templates that display popover information for matched or tagged content. An authenticated attacker can inject malicious code into tracked items that will execute in other users' browsers when they view the popovers, potentially allowing unauthorized data access or impersonation.

Technologies: [Ail-Project AIL framework](https://junglewise.ai/threats/technologies/ail-framework). Vendors: [Ail-Project](https://junglewise.ai/threats/vendors/ail-project).

## Technical details

The vulnerability is a stored XSS in two Jinja2 templates (block_message.html and show_item.html) where dynamic values are interpolated directly into Bootstrap popover data-content attributes without proper HTML encoding. Because popovers are configured with data-html="true", injected markup is interpreted as HTML/JavaScript. An authenticated attacker can inject arbitrary code through match, tracking, or tag-related data fields; the payload persists and executes when other users view affected content.
