The Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.1.23. This is due to the PermissionManager::manage_permissions() function being registered as a callback on WordPress core's map_meta_cap filter and unconditionally returning the always-true 'exist' primitive for every capability check whenever the evaluated user ID is 1, without scoping this behavior to plugin-specific capabilities. This makes it possible for authenticated attackers whose account is user ID 1, even subscribers, to pass every WordPress capability check, including manage_options, edit_plugins, edit_themes, promote_users, and update_core, thereby elevating their privileges to administrator-equivalent power and achieving full site takeover, including remote code execution via the plugin and theme editors. Exploitation is only impactful when user ID 1 has been deliberately demoted to a lower-privilege role as a common administrator-account hardening practice; on default installations where user ID 1 retains the administrator role, no incremental privilege gain occurs.

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 total (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".

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 100 of 145 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. None are among the latest 100 rows. The 45 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
