CVSS 3.1
8.8 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVE-2026-24844
High (8.8) in chainguard melange. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in chainguard.dev/melange 0.40.3.
melange allows users to build apk packages using declarative pipelines. From version 0.3.0 to before 0.40.3, an attacker who can provide build input values, but not modify pipeline definitions, could execute arbitrary shell commands if the pipeline uses ${{vars.*}} or ${{inputs.*}} substitutions in working-directory. The field is embedded into shell scripts without proper quote escaping. This issue has been patched in version 0.40.3.
