The CVE record names the fixed release — apply it.

An incorrect authorization vulnerability was identified in GitHub Enterprise Server, allowing for escalation of privileges in GraphQL API requests from GitHub Apps. This vulnerability allowed an app installed on an organization to gain access to and modify most organization-level resources that are not tied to a repository regardless of granted permissions, such as users and organization-wide projects. Resources associated with repositories were not impacted, such as repository file content, repository-specific projects, issues, or pull requests. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.7.1 and was fixed in versions 3.3.16, 3.4.11, 3.5.8, 3.6.4, 3.7.1. This vulnerability was reported via the GitHub Bug Bounty program.

SSVC (CISA's decision table, applied by EchelonGraph)Track at every mission impact level.

The CVE record names the fixed release. Apply it within your standard update timelines.

Exploitation none (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 8× in last 7d / 23× 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 88 of 154 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. 12 repeat rows among the latest 100 are merged into the row they repeat. The 66 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
