CVE-2026-60004: Gitea Code Injection Vulnerability

CVE-2026-60004 is a code injection weakness in Gitea that can let someone who already has write access to a repository abuse a patch-related API path to install a malicious Git hook. Once that hook is in place, commands can run with the privileges of the Gitea service account. That matters because Gitea often holds source code, CI secrets, deploy keys, and organizational trust relationships; compromise of the service account can extend far beyond a single repo.

Public detail is limited to the class of issue and the access model described by CISA. Confirm exact affected builds, fixed releases, and configuration notes against the vendor advisory before you act.

How it works

This issue is tracked as CWE-94 (improper control of code generation / code injection). In plain terms, the product accepts attacker-influenced input in a context where that input can become executable behavior rather than inert data.

According to the CISA summary, an attacker who already has repository write access can send a malicious patch to the diffpatch API endpoint. That path is intended to apply patch content; the flaw allows the attacker to plant an executable Git hook. Git hooks run in response to repository events, so a planted hook can cause shell commands to execute as the Gitea service account when normal Git operations occur.

No public exploit mechanics beyond that summary are provided here. Do not assume unauthenticated remote code execution: the described abuse requires write access to a repository. Treat any account or token that can push or otherwise write to repos as in scope for abuse of this class of flaw.

Am I affected? How to find it in your systems

Gitea is a self-hosted Git service commonly deployed on Linux servers, containers, or internal VMs for source control, code review, and lightweight CI integration. It may face the internet, sit on a corporate VPN, or run only on internal networks.

• Inventory: Search configuration management, container registries, package inventories, reverse-proxy configs, and internal DNS for hosts named or labeled Gitea; check listening services and reverse proxies that terminate Git HTTP/SSH.
• Version and build: Record the running Gitea version and deployment method (binary, package, container image). Compare only against the vendor advisory; do not rely on third-party version lists that are not confirmed here.
• Access model: Enumerate users, organizations, teams, deploy keys, and personal access tokens with repository write or admin rights. Shared or over-privileged write access increases blast radius for this weakness class.
• API exposure: Note whether the HTTP API (including patch/diff-related endpoints) is reachable from untrusted networks and whether authentication and authorization are enforced consistently at the edge.
• Telemetry signs: Review Gitea and reverse-proxy logs for unusual authenticated calls to patch/diff API paths; inspect repositories for unexpected Git hooks under hook directories; watch process and audit logs on the Gitea host for shell activity spawned by the Gitea service account; alert on sudden creation or modification of hooks, unexpected outbound connections from the Gitea host, or privilege use inconsistent with normal Git operations.

Absence of obvious log noise does not prove safety. Confirm patch status with the vendor advisory.

How to remediate

Patch first. Apply the vendor-supplied update for Gitea as named in the official advisory, following your normal change and test process. CISA’s required action direction is to apply mitigations in accordance with vendor instructions and to follow applicable BOD 26-04 prioritization and forensics-triage guidance; for cloud-hosted or managed instances, follow BOD 26-04 cloud guidance or discontinue use if mitigations are unavailable. Stakeholders must evaluate internet exposure and meet BOD 26-04 patching expectations for each asset.

• After upgrading, restart services as the vendor directs and verify the running version matches the fixed release.
• Re-audit repository write permissions; remove unused tokens and deploy keys; enforce least privilege on teams and bots.
• Review all repositories for unexpected hooks and remove unauthorized hook scripts; restore hooks only from known-good configuration management.
• Rotate credentials and secrets that the Gitea service account could have read (database passwords, object-storage keys, CI secrets, SSH keys) if you suspect abuse.
• Harden the host: run Gitea under a dedicated low-privilege account if not already, restrict filesystem permissions on repositories and hook paths, and keep the OS and Git runtime current per your baseline.

If you can't patch immediately

Compensating controls reduce—but do not eliminate—risk until the vendor fix is installed.

• Segmentation: Limit network access to Gitea admin and API interfaces to trusted management networks and VPN groups; block general internet access to the API if business allows.
• Access reduction: Temporarily freeze or tightly review write access; disable or restrict accounts that do not need push rights; require stronger authentication on accounts that retain write.
• Feature or path controls: If the vendor or your reverse proxy can disable or tightly restrict the diffpatch (or equivalent patch-application) API for untrusted callers, do so until patched—confirm supported options in vendor documentation.
• Virtual patching / WAF: Where a WAF or API gateway sits in front of Gitea, add strict allowlists and anomaly rules for authenticated patch/diff API usage; tune to your traffic so you do not rely on untested signatures alone.
• Monitoring: Heighten alerting on hook directory changes, service-account shell spawns, and unusual API sequences; retain logs for incident review consistent with your forensics requirements.
• Exposure decision: If you cannot mitigate and the instance is internet-facing with broad write access, treat continued operation as elevated risk and escalate for emergency patching or temporary shutdown per BOD 26-04-oriented risk decisions.

If your data may have been exposed

Actively exploited code-injection flaws in source-control platforms can lead to repository tampering, secret theft, and downstream compromise of build and deploy systems. Known ransomware use is not documented for this CVE in the facts provided; still investigate if you see evidence of unauthorized hooks or service-account activity. If you believe your environment was touched, follow your incident process: isolate the host as needed, preserve logs and hook artifacts, rotate secrets the Gitea account could access, and validate integrity of critical repositories. You can also run a free exposure scan of your email addresses against known breach datasets to see whether related identities already appear in public breach collections, then prioritize password resets and MFA on those accounts.
