Impact
Gitea versions up to 1.26.1 lack repository‑unit authorization on the issue‑template API endpoints, which may allow users to read or modify issue templates without proper repository privileges. This can expose repository‑specific information or let attackers inject malicious content into new issues. The weakness corresponds to CWE‑862, Missing Authorization Check.
Affected Systems
Gitea Open Source Git Server versions 1.26.1 or earlier are affected. The vulnerability exists in the issue‑template API endpoints exposed by these releases. Users who have any account on the Gitea instance and can target the API are at risk, while higher‑privileged administrators are protected once the patch in 1.26.2 is applied.
Risk and Exploitability
The CVSS score of 4.3 indicates moderate severity. An EPSS score below 1 % suggests a very low chance of active exploitation, and the vulnerability is not in CISA’s KEV catalog. Based on the description, the likely attack vector is a crafted HTTP request to the vulnerable issue‑template endpoints, which an attacker can perform from any authenticated session lacking proper repository permissions.
