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

The AIL Framework's username timeline feature is vulnerable to stored cross-site scripting (XSS). Usernames imported from chats and crawled forums are stored without character restrictions. When an authenticated analyst views the username timeline, the application renders these stored usernames into the DOM using D3's html() method in the tooltip. Because the username value (d.obj) is interpolated directly into an HTML string without sanitization, a crafted username containing HTML event handlers (e.g., ) will execute arbitrary JavaScript in the analyst's browser when the analyst hovers over the corresponding timeline entry. The attack requires the victim to be an authenticated analyst with access to the timeline view and to interact with the malicious timeline entry (hover). Successful exploitation can lead to session hijacking, data exfiltration, or unauthorized actions performed within the analyst's authenticated session. The vulnerability resides in the client-side JavaScript file var/www/static/js/d3/timeline_basic.js.

EG Risk 38/100

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. Higher = act sooner.

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".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed its CVE.org record (CNA or CISA ADP). An arrow marks a change the record states ("CVSS → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).

Frequently asked(5)

What is CVE-2026-100176?
CVE-2026-100176 is a high-severity vulnerability; its CVE record was published on September 25, 2026. The AIL Framework's username timeline feature is vulnerable to stored cross-site scripting (XSS). Usernames imported from chats and crawled forums are stored without character restrictions. When an authenticated analyst views the username timeline, the application renders these stored usernames…
When was the CVE record for CVE-2026-100176 published?
The CVE record for CVE-2026-100176 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-2026-100176 actively exploited?
CVE-2026-100176 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (29th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-100176?
CVE-2026-100176 has a CVSS base score of 8.5 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-100176?
An upstream fix for CVE-2026-100176 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-2026-100176 are linked in the Vendor Advisories panel on this page.
