Recommended response

Check inventory. Check lockfiles and deployed manifests for ail project/ail framework.
Review the reported fix. Source-reported solution: The fix removes all capture-derived values (item IDs, URLs, screenshot paths) from inline JavaScript contexts (onclick attributes and inline script variable assignments). These values are now stored in HTML data attributes (data-screenshot, data-url, data-item-id), which are properly HTML-escaped by the Jinja2 template engine. Screenshot click handlers are bound programmatically via addEventListener on elements with a .reload-image class, and the reload_image function reads values from the DOM element's dataset rather than receiving raw string parameters. Additionally, item IDs are URL-encoded with encodeURIComponent before being appended to link hrefs, preventing injection through the ID field.

Upstream source description

The AIL Framework crawler splash domain page (showDomain.html) is vulnerable to stored cross-site script injection (XSS). User-supplied data originating from imported crawler captures—specifically item IDs, URLs, and screenshot file paths—was interpolated directly into inline JavaScript contexts within the HTML template. This included an onclick attribute that embedded raw screenshot and URL values into a JavaScript function call, and an inline script block that assigned a screenshot value to a JavaScript variable without escaping. An attacker with a user-role API client could craft a malicious crawler capture import containing JavaScript payloads in these fields. When any user (including privileged users) subsequently viewed the affected domain page, the injected script would execute in the victim's browser context, potentially allowing session hijacking, data exfiltration, or unauthorized actions on behalf of the victim. The vulnerability is stored in the application's data layer and triggered upon page rendering, requiring no further interaction beyond loading the domain view.
