How severe is CVE-2021-22510?

CVE-2021-22510 has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

How do I fix CVE-2021-22510?

Update org.jenkins-ci.plugins:hp-application-automation-tools-plugin to 6.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-22510 is resolved across your whole dependency graph.

How do I detect CVE-2021-22510 in my Maven dependencies?

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

How do I mitigate CVE-2021-22510 if there is no patch (or I can't update yet)?

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.

Is CVE-2021-22510 actively exploited in the wild?

No public exploit code has been indexed for CVE-2021-22510 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-2021-22510?

CVE-2021-22510 has an EPSS (Exploit Prediction Scoring System) score of 5.0%, placing it in the 92th 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.

What type of vulnerability is CVE-2021-22510?

CVE-2021-22510 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2021-22510 published, and has it been updated?

CVE-2021-22510 was published on May 24, 2022 and was last updated on February 16, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
