How severe is CVE-2025-47271?

No CVSS score has been assigned to CVE-2025-47271 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-47271?

CVE-2025-47271 affects the following packages: OZI-Project/publish (GitHub Actions). Ecosystems affected: GitHub Actions.

How do I fix CVE-2025-47271?

Update OZI-Project/publish to 1.13.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-47271 is resolved across your whole dependency graph.

How do I detect CVE-2025-47271 in my GitHub Actions dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for OZI-Project/publish. 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.

How do I mitigate CVE-2025-47271 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2025-47271?

O3 pinpoints whether CVE-2025-47271 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-47271 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-47271 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-47271?

CVE-2025-47271 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 27th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2025-47271 published, and has it been updated?

CVE-2025-47271 was published on May 12, 2025 and was last updated on April 2, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

📦OZI-Project/publish

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects GitHub Actions packages — download data is not available via public APIs for these ecosystems.

Description

The OZI action is a GitHub Action that publishes releases to PyPI and mirror releases, signature bundles, and provenance in a tagged release. In versions 1.13.2 through 1.13.5, potentially untrusted data flows into PR creation logic. A malicious actor could construct a branch name that injects arbitrary code. This is patched in 1.13.6. As a workaround, one may downgrade to a version prior to 1.13.2.
