Technical details
The AI Automator submodule fails to properly validate access controls for text formats when automatically populating fields via AI. An attacker with low privileges can exploit this to write field data in text formats restricted to higher-privilege users, leading to cross-site scripting (XSS) payload injection. The vulnerability affects versions before 1.4.11 and 1.5.0 through 1.5.1.
