CVE-2026-27660: Gitea draft releases use insufficient permission checks

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Gitea Gitea Open Source Git Server 1.25.5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Gitea Gitea Open Source Git Server 1.25.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Gitea versions before 1.25.5 allow draft release data or attachments to be accessed without the required write permission.
