Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Citizen from 3.3.0 to 3.9.0 are vulnerable to stored cross-site scripting in the sticky header button message handling. In stickyHeader.js the copyButtonAttributes function assigns innerHTML from a source element’s textContent when copying button labels. This causes escaped HTML in system message content (such as citizen-share, citizen-view-history, citizen-view-edit, and nstab-talk) to be interpreted as HTML in the sticky header, allowing injection of arbitrary script by a user with the ability to edit interface messages. The vulnerability allows a user with the editinterface right but without the editsitejs right (by default the sysop group has editinterface but may not have editsitejs) to execute arbitrary JavaScript in other users’ sessions, enabling unauthorized access to sensitive data or actions. The issue is fixed in 3.9.0.

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 public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. 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".

Data Freshness Timeline
(refreshed 10× in last 7d / 42× in last 30d)
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 it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 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). Most recent first.
Showing the most recent 95 of 225 refreshes on record for this CVE.
A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 5 repeat rows among the latest 100 are merged into the row they repeat. The 130 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
