Summary

CVE-2026-33003 is a medium-severity Cleartext Storage of Sensitive Information (CWE-312) vulnerability in Jenkins Loadninja. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and SC-28 (Protection of Information at Rest) — see the control section below for these in your framework.

Vulnerability Data

Jenkins LoadNinja Plugin 2.1 and earlier stores LoadNinja API keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires cryptographic protection of sensitive data (API keys) stored at rest in config.xml files.

prevent

Enforces least privilege so that only necessary users receive Item/Extended Read permission or file-system access to job configs.

prevent

Enforces access-control policy on Jenkins job configuration objects and underlying files to block unauthorized disclosure of credentials.

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

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.

mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

mitigates

Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.

A.8.11 Data masking partial match
mitigates

Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.

detects

When clear-text sensitive data is detected leaving controlled storage, the control can block the transfer, thereby limiting the exposure that would result from unencrypted storage on external media or cloud services.

mitigates

By insisting that any retained test copies be stored securely and only for testing, the control reduces the likelihood that clear-text operational data will persist on disk or in backups.
