Real-World Exposure
org.jenkins-ci.plugins:structsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Structs Plugin provides utility functionality used, e.g., in Pipeline to instantiate and configure build steps, typically before their execution.
When Structs Plugin 337.v1b_04ea_4df7c8 and earlier fails to configure a build step, it logs a warning message containing diagnostic information that may contain secrets passed as step parameters.
This can result in accidental exposure of secrets through the default system log.
Structs Plugin 338.v848422169819 inspects the types of actual parameters before logging these warning messages, and limits detailed diagnostic information to FINE level log messages if secrets are involved. These log messages are not displayed in the default Jenkins system log.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:structs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:structs to 338.v848422169819 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-39458 is resolved across your whole dependency graph.
Workarounds
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.
