1) OS Command Injection (CVE-ID: CVE-2026-42290)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary shell commands.

The vulnerability exists due to command injection in the pbts CLI tool when processing attacker-influenced input file paths. A remote attacker can supply a crafted file path containing shell metacharacters to execute arbitrary shell commands.

User interaction is required because an application or user must invoke pbts on attacker-influenced paths.
