Summary
CVE-2023-28669 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Jacoco. Its CVSS base score is 5.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked at the 45th percentile by exploit likelihood (below the median); 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.
Jenkins JaCoCo Plugin 3.3.2 and earlier contains a stored cross-site scripting vulnerability because it fails to escape class and method names rendered in the user interface. The affected component is the post-build action that records JaCoCo coverage reports within Jenkins.
Attackers who can supply or modify the input files processed by this action are able to inject malicious scripts that execute in the browsers of other users viewing the coverage results, achieving limited impact on confidentiality and integrity under the reported CVSS vector.
The Jenkins security advisory published on 2023-03-21 details the issue under SECURITY-3061 and provides the primary reference for mitigation steps, including any available plugin updates.
The associated EPSS score has remained near 0.09 with only a minor peak and does not indicate a significant post-disclosure increase in exploitation interest.

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.
