CVE-2026-4821
AI Analysis
Technical Summary
This vulnerability (CVE-2026-4821) in GitHub Enterprise Server versions 3.14.0 to 3.20.0 is classified as CWE-78 (OS command injection). The CVSS 4.0 vector indicates it requires local access (AV:L), low attack complexity (AC:L), no privileges required for attack (PR:H means high privileges are required), no user interaction (UI:N), and impacts confidentiality, integrity, and availability with high severity. The vulnerability is published but lacks an official remediation level or patch information. No known exploits have been reported.
Potential Impact
The vulnerability could allow an attacker with high privileges and local access to execute arbitrary OS commands, potentially compromising system confidentiality, integrity, and availability. Since it requires high privileges and local access, remote exploitation is not indicated. No known exploits in the wild have been reported to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users with high privileges and monitor for suspicious activity related to command execution. Follow GitHub's advisories for updates.
