CVE-2021-23406: Improper Control of Generation of Code ('Code Injection')

September 2, 2021 (updated September 26, 2022)

This affects the package pac-resolver before 5.0.0. This can occur when used with untrusted input, due to unsafe PAC file handling. NOTE: The fix for this vulnerability is applied in the node-degenerator library, a dependency written by the same maintainer.
