CVE-2021-44532 is a medium-severity vulnerability affecting Node.js versions prior to 12.22.9, 14.18.3, 16.13.2, and 17.3.1, as well as Debian and Oracle products. It stems from an injection vulnerability in how Node.js converts Subject Alternative Names (SANs) to strings for peer certificate validation, allowing name constraint bypass. With a CVSS score of 5.3, this network-exploitable vulnerability could lead to low integrity impact without requiring user interaction or privileges. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.

CVE-2021-44532
Mar 8, 2022Node.js < 12.22.9 < 14.18.3 < 16.13.2 and < 17.3.1 converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain allowing the bypass of these name constraints.Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.
