CVE-2025-47933 is a critical-severity (CVSS 9) Cross-site Scripting (XSS) vulnerability in github.com/argoproj/argo-cd. O3 Security confirms whether CVE-2025-47933 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Argo CD allows cross-site scripting on repositories page
Real-World Exposure
github.com/argoproj/argo-cd🐹github.com/argoproj/argo-cd/v2🐹github.com/argoproj/argo-cd/v2🐹github.com/argoproj/argo-cd/v3Real-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
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.13.8, 2.14.13, and 3.0.4, an attacker can perform arbitrary actions on behalf of the victim via the API. Due to the improper filtering of URL protocols in the repository page, an attacker can achieve cross-site scripting with permission to edit the repository. This issue has been patched in versions 2.13.8, 2.14.13, and 3.0.4.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/argoproj/argo-cd. 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.
Fix
No patched version of github.com/argoproj/argo-cd has shipped for CVE-2025-47933 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Workarounds
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 CVE-2025-47933 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 CVE-2025-47933. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-47933 in your dependencies?
O3 detects CVE-2025-47933 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
