Description
Summary
It was confirmed in a test environment that an attacker can store an HTML/JavaScript payload in a repository’s Milestone name, and when another user selects that Milestone on the New Issue page (/issues/new), a DOM-Based XSS is triggered.
Impact
- Theft of information accessible in the victim’s session.
- Extraction of CSRF tokens and submission of state-changing requests with the victim’s privileges.
- Repository operations performed with the victim’s privileges (Issue operations, settings changes, etc.).
(The impact scope depends on the victim’s permission level.)

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gogs.io/gogs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of gogs.io/gogs for GHSA-vgjm-2cpf-4g7c. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
