CVE-2026-89309

Critical

Description

The authorization middleware of the WMS MobileServer fails to require authentication in two distinct cases. First, it only requires an Authorization header for GET and HEAD requests; requests using any other HTTP method are processed without an authentication check. Second, for any HTTP method including GET and HEAD, a request carrying a malformed or non-bearer Authorization header is passed through without a valid token being required. The middleware does validate a token whenever a well-formed one is present, but in these two cases it does not require one. A remote attacker with network access to the service can therefore invoke API functionality without valid credentials.
