Summary

CVE-2025-64145 is a medium-severity Missing Encryption of Sensitive Data (CWE-311) vulnerability in Jenkins Byteguard Build Actions. Its CVSS base score is 4.3 (Medium).

Operationally, ranked at the 6th 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.

Mitigating Controls (NIST 800-53 r5) AI

IA-5 Authenticator Management good match
prevent

IA-5 requires secure authenticator management that directly prohibits plaintext exposure of API tokens in configuration interfaces.

SI-15 Information Output Filtering good match
prevent

SI-15 mandates output filtering to suppress sensitive data such as credentials from being rendered in user-facing forms.

AC-3 Access Enforcement partial match
prevent

AC-3 enforces access decisions that can be used to ensure tokens are never presented in cleartext regardless of user authorization level.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

PR.DS-01 directly mandates encryption for data-at-rest and therefore prevents CWE-311 mostly for storage, yet the weakness also spans transmission and other contexts that this single at-rest control leaves unaddressed.

PR.DS-02 partial match
prevents

PR.DS-02 directly eliminates the transmission facet of CWE-311 via mandatory encryption but leaves the storage facet untouched, so each direction rates only partial.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

A.5.14 Information transfer partial match
prevents

Explicit rules requiring encryption for sensitive information in transit eliminate the weakness of sending data without cryptographic protection.

A.8.26 Application security requirements partial match
prevents

Explicitly calling for protection of data in transit and at rest, plus secure encryption of communications, drives the implementation of encryption that prevents clear-text exposure of sensitive information.
