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

The AIL Framework tag selector component (var/www/static/js/tags.js) is vulnerable to stored cross-site scripting (XSS). A user with the ability to create a custom tag could embed an HTML payload containing JavaScript event handlers (e.g., or ) in the tag name. When another authenticated user opened a page containing the tag selector, the malicious tag name was inserted into the DOM using jQuery's html property, causing the embedded script to execute in the victim's browser context.

The vulnerable code paths affected both the suggestion/combo-item rendering (_renderComboItems) and the selected-tag rendering logic. In both cases, the display value derived from the tag's displayField was passed directly to the html property of a jQuery element constructor, which parses and inserts the string as raw HTML rather than as text.

Preconditions: the attacker must have an authenticated account with permission to create custom tags, and the victim must be an authenticated user who views a page that renders the tag selector with the attacker's stored tag. The attack is stored (persistent) and does not require the victim to perform any action beyond loading the page.

Security impact: successful exploitation allows arbitrary JavaScript execution in the victim's browser within the application's origin, potentially leading to session hijacking, unauthorized data access, form manipulation, or further client-side attacks.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment).

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Frequently asked(5)

What is CVE-2026-100174?
CVE-2026-100174 is a medium-severity vulnerability; its CVE record was published on September 25, 2026. The AIL Framework tag selector component (var/www/static/js/tags.js) is vulnerable to stored cross-site scripting (XSS). A user with the ability to create a custom tag could embed an HTML payload containing JavaScript event handlers (e.g., <img src=x onerror=alert(1)> or <svg onload=...>) in the…
When was the CVE record for CVE-2026-100174 published?
The CVE record for CVE-2026-100174 was published on September 25, 2026. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of September 25, 2026; the record at its source may have been updated since.
Is CVE-2026-100174 actively exploited?
CVE-2026-100174 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (34th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-100174?
CVE-2026-100174 has a CVSS base score of 5.1 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-100174?
An upstream fix for CVE-2026-100174 has been merged but is not yet in a tagged release. Until it ships, restrict network exposure of the affected system or apply the vendor's mitigation, then update to the release that contains the fix. The vendor advisories EchelonGraph has for CVE-2026-100174 are linked in the Vendor Advisories panel on this page.
