CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-33002 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Testcomplete Support. Its CVSS base score is 5.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 17% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The Jenkins TestComplete support Plugin 2.8.1 and earlier contains a stored cross-site scripting vulnerability because it fails to escape the TestComplete project name when rendering configuration or build views. The affected component is the Jenkins plugin that integrates TestComplete test projects into Jenkins jobs, and the flaw is tracked as CWE-79 with a CVSS 3.1 score of 5.4.
Attackers who possess Item/Configure permission on a Jenkins item can supply a malicious project name that is stored and later executed in the browsers of other users who view the affected job configuration or results, enabling theft of session tokens or other actions within the Jenkins web interface.
The Jenkins security advisory published on 2023-05-16 at the referenced URL describes the issue under SECURITY-2892 and directs administrators to update the plugin to a version that properly escapes the project name.
The EPSS score reached a peak of 0.1345 with a current value of 0.1172, indicating moderate but not sharply rising exploitation interest after disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
