CVE-2020-7729

25
FAUCET Score

CVE-2020-7729 is an arbitrary code execution vulnerability affecting versions of the Grunt package prior to 1.3.0, stemming from its use of the insecure load() function from js-yaml instead of safeLoad() within grunt.file.readYAML. This high-severity vulnerability (CVSS 7.1) requires low privileges and user interaction, but has high impact on confidentiality, integrity, and availability, with a high attack complexity. Despite its potential impact, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
