CVE-2024-27920

Code execution via unsigned workflow templates

Published Mar 15, 2024 · Updated Aug 2, 2024

Command injection in Nuclei 3.0.0 and later before 3.2.0 allows context-dependent attackers to execute code through an untrusted workflow. The workflow parser appended referenced code-protocol templates without enforcing the code-enabled and signature-verification checks applied to direct template execution. Execution requires an operator or SDK host to accept an attacker-supplied workflow and enable code templates, granting the template the host process's data access and command privileges.
