Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Umbraco.Cms.Api.Management versions 14.0.0 up to but not including 14.1.2 can return stack trace information in error responses from some Management API endpoints, even when debug mode is disabled. The source does not describe the attacker's required access, though the issue is triggered by requests such as paging with negative numbers. Upgrade to version 14.1.2 or later. No workaround is listed.
