CRITICAL

UiPath Assistant - Stored Cross-Site Scripting via URI Handler Error Message

Title source: llm
STIX 2.1

Description

An issue was discovered in UiPath Assistant 21.4.4. User-controlled data supplied to the --process-start argument of the URI handler for uipath-assistant:// is not correctly encoded, resulting in attacker-controlled content being injected into the error message displayed (when the injected content does not match an existing process). A determined attacker could leverage this to execute JavaScript in the context of the Electron application.
