CVE-2026-73377Network attack vector

Integrity impact via missing authorization

Published Aug 18, 2026 · Updated Aug 18, 2026

Broken access control in Ultimate Maps by Supsystic before 1.5.0 allows remote attackers to modify data via unspecified vectors. Patchstack, the CNA, describes the flaw only as missing authorization on an unauthenticated path and does not identify the vulnerable endpoint, action, or function in public records. Reachability is network-based and requires no authentication or user interaction; the published CVSS confines the demonstrated impact to integrity rather than data disclosure or service interruption.
