GHSA-vgjm-2cpf-4g7c is a high-severity (CVSS 7.3) Cross-site Scripting (XSS) vulnerability in gogs.io/gogs. O3 Security confirms whether GHSA-vgjm-2cpf-4g7c is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Gogs: DOM-based XSS via milestone selection
Real-World Exposure
gogs.io/gogsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
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.)
Remediation
A fix is available at https://github.com/gogs/gogs/releases/tag/v0.14.2

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gogs.io/gogs. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of gogs.io/gogs has shipped for GHSA-vgjm-2cpf-4g7c yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-vgjm-2cpf-4g7c is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-vgjm-2cpf-4g7c. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-vgjm-2cpf-4g7c in your dependencies?
O3 detects GHSA-vgjm-2cpf-4g7c across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
