What is CVE-2026-86177?

The Pterodactyl Panel prior to version 1.14.1 has a vulnerability that arises from improper validation of action-specific permissions during the creation of scheduled tasks. This oversight allows subusers with merely the 'schedule.update' permission to execute arbitrary console commands. As a result, attackers can create and activate scheduled tasks that may control server operations, such as changing the power state of the server or making backups, without undergoing the necessary authorization checks.

Affected Version(s)

panel 0 < 1.14.1

panel 1.14.1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
