# CVE-2026-60004: Gitea Code Injection Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Gitea Gitea. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-08-25, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-08-28 ; treat that as the outer limit, not the target.
- EPSS 24.0% , percentile 98: FIRST’s model estimates a 24.0% chance of exploitation activity in the next 30 days, higher than 98% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes gitea.dev (Go) >= 1.17.0, < 1.27.1, fixed in 1.27.1 . Check your lockfile, including transitive dependencies.
- Editorial verdict: Act now. Gitea CVE-2026-60004: Exploited RCE via diffpatch API — Upgrade every self-hosted Gitea below 1.27.1 today and close open registration; automated attacks sign up, create a repo and get a shell in seconds, and a proof of concept is public.

## What it is

Gitea before 1.27.1 allows remote code execution via the diffpatch API through Git hook installation.

## Affected packages

- Go `gitea.dev` >= 1.17.0, < 1.27.1 → fixed: 1.27.1

## Affected products (CVE record)

- Gitea Gitea: 1.17 < 1.27.1

## Severity

- mitre CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2026-08-25; federal due date 2026-08-28. Known ransomware use: Unknown.
- CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 23.99% probability of exploitation activity in the next 30 days; percentile 98.
