## How to fix

- Fixed in Octopus Server 2026.2.13487, 2026.3.15863

## Technical details

Incorrect validation of permissions for users creating project triggers in Octopus Server allows privilege escalation to perform unauthorized runbook execution and deployment creation. The vulnerability exists in multiple versions from 2019.11 onwards through 2026.2.x and early 2026.3.x builds. An authenticated attacker with project trigger creation permissions can bypass authorization checks via a flawed permission validation mechanism.
