This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3% (16th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

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.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

CISA SSVC: Track at low or medium mission impact; Track or Attend at high (mission-essential systems).
Action: An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high until it ships, then apply the release.

CISA SSVCTrack at low or medium mission impact; Track or Attend at high (mission-essential systems).

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high until it ships, then apply the release.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
