CVE-2026-95106: Gitea review and execution mismatch through duplicate tree entries

• Severity: critical (CVSS 9.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-06 · updated 2026-10-13
• Weakness: CWE-706

Description

Gitea accepted pushed Git trees containing two entries with the same name, which Git's own consistency checks reject. Gitea's web views resolved such a path to the first entry, while `git checkout`, Gitea Actions, and release archives use the last. A contributor could open a pull request whose diff and file views show benign content while CI and checkouts at the same commit use different, attacker-controlled content. Incoming objects are now checked for consistency; objects already stored in existing repositories are not rescanned.
