Nuclei is a vulnerability scanner built on a simple YAML-based DSL. From 3.0.0 until 3.10.0, the Goja JavaScript runtime embedded in the javascript: protocol under pkg/js/ contains an out-of-bounds heap write that can corrupt memory during template evaluation and allow native code execution on the scanner host. A malicious untrusted JavaScript template can trigger the flaw during a normal scan, including from a template init section that runs during initialization. JavaScript templates execute without the -code flag and unsigned JavaScript templates run by default on affected versions, exposing CLI and SDK deployments that accept third-party templates. This issue is fixed in version 3.10.0.
