CVE-2026-33623 identifies a high-severity command injection vulnerability in PinchTab v0.8.4, specifically within its Windows-only Chrome cleanup routine. This flaw allows authenticated attackers with administrative-equivalent API access to execute arbitrary PowerShell commands on the host. Exploitation occurs by crafting a profile name that leverages improper metacharacter neutralization during the cleanup process, leading to high impact on confidentiality, integrity, and availability (CVSS 7.2 HIGH). The resulting command execution inherits the permissions of the PinchTab process user. There is no evidence of active exploitation, public exploit code, or significant community attention for this vulnerability.
