ecosystem impact- 9 npm packages depend on codecov (3 direct, 6 indirect)
Ecosystem-wide dependent count for version 3.6.5.
DescriptionNVD
codecov-node npm module before 3.6.5 allows remote attackers to execute arbitrary commands.The value provided as part of the gcov-root argument is executed by the exec function within lib/codecov.js. This vulnerability exists due to an incomplete fix of CVE-2020-7596.
AnalysisAI
codecov-node npm module before 3.6.5 allows remote attackers to execute arbitrary commands.The value provided as part of the gcov-root argument is executed by the exec function within lib/codecov.js. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Technical ContextAI
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. codecov-node npm module before 3.6.5 allows remote attackers to execute arbitrary commands.The value provided as part of the gcov-root argument is executed by the exec function within lib/codecov.js. This vulnerability exists due to an incomplete fix of CVE-2020-7596. Affected products include: Codecov. Version information: before 3.6.5.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
