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)?

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-2021-22510?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2021-22510 can be triaged on real exposure rather than presence alone.

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.

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.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

CVE-2021-22510 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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

Description

Micro Focus Application Automation Tools Plugin 6.7 and earlier does not escape user input in a form validation response.

This results in a reflected cross-site scripting (XSS) vulnerability.

Micro Focus Application Automation Tools Plugin 6.8 escapes user input in the affected form validation response.

A security hardening since Jenkins 2.275 and LTS 2.263.2 prevents exploitation of this vulnerability.
