Which packages are affected by CVE-2023-28671?

CVE-2023-28671 affects the following packages: org.jenkinsci.plugins:octoperf (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-28671?

Update org.jenkinsci.plugins:octoperf to 4.5.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-28671 is resolved across your whole dependency graph.

How do I detect CVE-2023-28671 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkinsci.plugins:octoperf, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-28671 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.

Is CVE-2023-28671 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-28671 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.
