CVE-2026-24844 affects Chainguard Melange versions 0.3.0 through 0.40.2, allowing attackers to execute arbitrary shell commands. This high-severity vulnerability (CVSS 8.8) arises from improper quote escaping when using variable substitutions in the 'working-directory' field of Melange's declarative build pipelines. While an attacker needs to provide build input values, they do not require pipeline modification privileges. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
