Description

The AIL Framework (ail-project/ail-framework) contains a stored cross-site scripting (XSS) vulnerability in two Jinja2 templates that render popovers for matched, tracked, or tagged content: var/www/templates/chats_explorer/block_message.html and var/www/templates/objects/item/show_item.html. In both templates, dynamic values associated with this content, including icon color, icon style, icon glyph, subtype, identifier, name, description, and matched value, are interpolated directly into the data-content HTML attribute of Bootstrap popover elements without appropriate output encoding. Because the popovers are configured with data-html="true", the content is interpreted as HTML in the victim's browser. An authenticated attacker who can influence matched, tracked, or tagged content may inject arbitrary HTML or JavaScript into these values. When a victim displays the affected popover, the injected markup may execute in the victim's session, potentially enabling data exfiltration or actions with the victim's privileges. The vulnerability is classified as stored XSS because the malicious payload can persist in the affected match, tracking, or tag-related data and be delivered to users who view the affected content.
