Umbraco.AI discloses sensitive application configuration values

Moderate severity GitHub Reviewed Published Jun 4, 2026 in umbraco/Umbraco.AI • Updated Jul 14, 2026

Package

nuget Umbraco.AI (NuGet)

Affected versions

<= 1.13.0

Patched versions

1.14.0

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
