CVE-2026-20750: Gitea improper access control in organization project operations

CVE-2026-20750 · Severity: critical · CVSS 9.1 · Published 2026-01-22

Technologies: code.gitea.io/gitea (Go), github.com/go-gitea/gitea (Go), Gitea. Vendors: Go, Red Hat, Gitea.

Executive brief

Gitea, a popular self-hosted Git service, was found to have a security flaw in how it handles organization projects. An authorized user with write access to projects in one organization could potentially modify or interfere with projects belonging to an entirely different organization. This could lead to unauthorized data modification or disruption of development workflows across different teams or clients hosted on the same server.

Technical details

An improper access control vulnerability (CWE-284) exists in Gitea's organization project operations due to insufficient validation of project ownership. The flaw allows a user who has been granted project write permissions within one organization to perform unauthorized operations on projects belonging to different organizations. The vulnerability is reachable over the network and does not require complex attack conditions, though it typically requires the attacker to have an existing account with project-level permissions. The issue was addressed by improving permission checks in organization project operations in Gitea version 1.25.4.
