CVE-2023-40339
No exploitation reported by the sources we read.
- Published2023-08-16
Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Jenkins Config File Provider Plugin 952.va_544a_6234b_46 and earlier does not mask (i.e., replace with asterisks) credentials specified in configuration files when they're written to the build log.
