CVE-2020-8137Network attack vector

Remote code execution

Published Mar 20, 2020 · Updated Aug 4, 2024

Code injection in Andrey Kucherenko blamer 1.0.0 and earlier allows remote attackers to execute code via attacker-controlled input. The public HackerOne reference and GitHub advisory do not identify the affected API, code path, or unsafe operation that processes the input. Exploitation requires a consuming application to pass attacker-controlled data into the package, after which injected code runs with the Node.js process's permissions.
