AnalysisAIv1 – Jul 22, 2026

Information disclosure in Gitea 1.26.2 lets a fork owner keep pulling commits from a parent repository via the merge-upstream API even after the parent was switched from public to private, exposing content the fork should no longer be authorized to see. The flaw stems from the synchronization endpoint failing to re-check the parent's current visibility, so data added during the private period leaks into a fork whose owner can no longer directly access the parent. A working proof-of-concept is publicly published and CISA SSVC rates exploitation automatable, but the issue is not on CISA KEV and EPSS is low (0.20%); it is fixed in Gitea 1.26.3.

DescriptionCVE.org

Gitea 1.26.2 allows fork synchronization to continue after a parent repository changes from public to private, exposing data to a fork that should no longer be authorized.

Executive ViewAI

Why It Matters

Gitea 1.26.2 contains an information disclosure vulnerability in its repository merge-upstream API that allows fork owners to access confidential content from parent repositories after they transition from public to private; publicly available exploit code exists. This exposes sensitive code and data to former collaborators, presenting a material compliance and intellectual property risk for organizations managing proprietary repositories.

Recommended Action

Within 24 hours, identify all Gitea instances running versions 1.26.0-1.26.2. Within 7 days, upgrade affected instances to Gitea 1.26.3 or later and verify the merge-upstream endpoint functions correctly post-upgrade. Within 30 days, conduct a repository access-control audit, review any repositories transitioned from public to private during the vulnerable period, and test fork synchronization behavior to confirm unauthorized access is blocked.

Business Impact: High

Compensating Controls

Apply vendor patch.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
