CVE-2025-67638 is a medium-severity Cleartext Storage of Sensitive Information (CWE-312) vulnerability in Jenkins Jenkins. Its CVSS base score is 4.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); 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 IA-5 (Authenticator Management) and SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires obscuring or protecting authenticator/token values (including build tokens) from unauthorized exposure during display or handling.
Filters sensitive information such as authorization tokens from being included in system output like configuration forms.
Reduces risk of information leakage through observation of displayed sensitive values on screens or output devices.

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.
Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.
Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.
Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.
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.
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.
