CVE-2026-86684 is a high-severity flaw (CVSS 7.1) affecting gitea. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Gitea push mirror API checked whether the repository owner, instead of the requesting user, may use local file system paths. On instances with `[security] IMPORT_LOCAL_PATHS = true`, a repository administrator who is not allowed to import local paths could add a push mirror to a local path on the server when the repository owner has that permission. Gitea then pushed the repository's refs into an existing Git repository at that path with the

gitea gitea UPGRADE

Affected: >= 1.18.0 and < 28.1.0

Fixed in: 28.1.0

Safe to downgrade to: a release before 1.18.0

1. Check installed version

apt-cache policy gitea || rpm -q gitea || gitea --version

2. UPGRADE to 28.1.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade gitea

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade gitea

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.18.0 (Debian / Ubuntu)

apt-cache madison gitea sudo apt install gitea=<VERSION_BEFORE_1.18.0> sudo apt-mark hold gitea

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list gitea sudo dnf downgrade gitea-<VERSION_BEFORE_1.18.0> sudo dnf versionlock add gitea

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
