Incorrect Authorization in GitHub Enterprise Server allows access to issue and commit search results without repo scope
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.41% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: GitHub Enterprise Server 3.16.15, 3.17.12, 3.18.6.
Low priority for now. Upgrade to GitHub Enterprise Server 3.16.15, 3.17.12, 3.18.6 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
An Incorrect Authorization vulnerability was identified in GitHub Enterprise Server that allowed an authenticated user with a classic personal access token (PAT) lacking the repo scope to retrieve issues and commits from private and internal repositories via the search REST API endpoints. The user must have had existing access to the repository through organization membership or as a collaborator for the vulnerability to be exploitable. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.20 and was fixed in versions 3.16.15, 3.17.12, 3.18.6 and 3.19.3. This vulnerability was reported via the GitHub Bug Bounty program.
