Real-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

Jenkins Credentials Binding Plugin versions 719.v80e905ef14eb\_ and earlier do not sanitize file names for file and zip file credentials.

This allows attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem. If Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node, this can lead to remote code execution.

Credentials Binding Plugin 720.v3f6decef43ea\_ sanitizes the file name provided for file and zip file credentials, preventing path traversal.

## Detection & mitigation playbook

Open-source dependency

1.  ### Detect
    
    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:credentials-binding, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
    
2.  ### Fix
    
    Update org.jenkins-ci.plugins:credentials-binding to 720.v3f6decef43ea or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-42520 is resolved across your whole dependency graph.
    
3.  ### Workarounds
    
    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
