How to Fix CVE-2024-36361
To remediate this vulnerability, upgrade all affected Pug code gen dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install pug-code-gen@3.0.3npm install pug@3.0.3Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls pug-code-genHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-36361, inspect your project dependencies using npm:
npm ls pug-code-genAnalyze the terminal output to locate any version of Pug code gen in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.3), your application is affected.
Note: The npm ls pug-code-gen command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Pug code gen, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
