Security readout for executives and security teams
Plain-English summary
Jenkins Walti Plugin 1.0.1 and earlier can store unsafe content received from the Walti API and later show it in Jenkins. If an attacker can influence those API responses, a Jenkins user viewing the affected page could have script run in their browser.
Executive priority
Treat as a moderate-priority Jenkins exposure. It is not presented as actively exploited, but stored XSS in CI/CD tooling can support account abuse or workflow tampering if privileged users are targeted.
Technical view
This is a stored cross-site scripting issue in Jenkins Walti Plugin caused by failing to escape information returned by the Walti API. The CVSS 3.1 score is 5.4 with network reachability, low complexity, low privileges, required user interaction, changed scope, and low confidentiality and integrity impact.
Likely exposure
Exposure is limited to Jenkins environments using the Walti Plugin at version 1.0.1 or earlier, where an attacker can provide or influence Walti API responses and a Jenkins user views the affected data.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not listed as KEV. Exploitation depends on attacker control over Walti API response content and user interaction in Jenkins.
Researcher notes
Evidence identifies CWE-79 and affected Jenkins Walti Plugin 1.0.1 and earlier. The public bundle does not provide exploit details, a confirmed patched version, or observed exploitation. Validate exposure through plugin inventory and integration trust boundaries.
Mitigation direction
- Identify Jenkins instances with Walti Plugin 1.0.1 or earlier.
- Check Jenkins advisory and plugin guidance for fixed versions or official mitigation.
- Disable or remove the plugin if it is not operationally required.
- Restrict who can influence Walti API responses or related integrations.
- Prioritize remediation for Jenkins instances used by administrators.
Validation and detection
- Inventory installed Jenkins plugins and record Walti Plugin versions.
- Confirm whether Jenkins consumes Walti API data from trusted sources only.
- Review Jenkins access paths where Walti Plugin data is rendered.
- Check logs and change history for unexpected Walti integration changes.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
