Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Umbraco.AI, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Under certain configurations, a user with elevated privileges may be able to cause sensitive application configuration values, potentially including secret material such as credentials, to be disclosed. Successful exploitation could expose confidential information and, depending on what the affected installation stores in configuration, enable further compromise. Exploitation requires access to the AI section of the backoffice and a specific custom AI provider, which limits real-world exposure. ### Patches Patched in 1.14.0 ### Workarounds Since the patch is a breaking change and requires a version jump, it is not recommended to try and implement a workaround. ### Resources * Announcement Blog Post: https://umbraco.com/blog/security-advisory-june-4-2026-security-patch-for-umbracoai-is-now-available/
