## What is CVE-2025-54059?

CVE-2025-54059 is a medium-severity vulnerability in chainguard-dev melange, published on 18 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

melange allows users to build apk packages using declarative pipelines. Starting in version 0.23.0 and prior to version 0.29.5, SBOM files generated by melange in apks had file system permissions mode 666. This potentially allows an unprivileged user to tamper with apk SBOMs on a running image, potentially confusing security scanners. An attacker could also perform a DoS under special circumstances. Version 0.29.5 fixes the issue.

Weakness: CWE-276 (Incorrect Default Permissions)
