CVE-2022-34183 — agent-server-parameter
HIGHCVE-2022-34183 is a high-severity (CVSS 8) Cross-site Scripting (XSS) vulnerability in io.jenkins.plugins:agent-server-parameter. No vendor fix is recorded yet; mitigation options are listed below.
Cross-site Scripting in Jenkins Agent Server Parameter Plugin
EPSS Exploitation Probability
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-2022-34183 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.

Description
Jenkins Agent Server Parameter Plugin 1.1 and earlier does not escape the name and description of Agent Server parameters on views displaying parameters, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.
Exploitation of this vulnerability requires that parameters are listed on another page, like the "Build With Parameters" and "Parameters" pages provided by Jenkins (core), and that those pages are not hardened to prevent exploitation. Jenkins (core) has prevented exploitation of vulnerabilities of this kind on the "Build With Parameters" and "Parameters" pages since 2.44 and LTS 2.32.2 as part of the SECURITY-353 / CVE-2017-2601 fix. Additionally, several plugins have previously been updated to list parameters in a way that prevents exploitation by default, see SECURITY-2617 in the 2022-04-12 security advisory for a list.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugins:agent-server-parameter, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of io.jenkins.plugins:agent-server-parameter has shipped for CVE-2022-34183 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-34183 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-34183. 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-2022-34183 in your dependencies?
O3 Security finds CVE-2022-34183 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
