CVE-2026-22739 is an improper path-limitation vulnerability in Spring Cloud Config Server's substitution of the request-supplied profile parameter. When Config Server uses the native file-system backend, crafted profile values can cause access to files outside configured search directories. When a source-control backend is used, profile substitution into the source-control repository URL can be abused to make server-side requests to attacker-selected destinations. Affected versions are Spring Cloud 3.1.x before 3.1.13, 4.1.x before 4.1.9, 4.2.x before 4.2.3, 4.3.x before 4.3.2, and 5.0.x before 5.0.2.
