CVE-2026-88126: WebDAV untrusted pointer dereference privilege escalation

CVE-2026-88126 · Severity: high · CVSS 7.8 · Published 2026-10-13

WebDAV is a file-sharing protocol often integrated into operating systems and enterprise software. This vulnerability allows an authorized user with local access to elevate their privileges to a higher level of system access through a memory handling defect. An attacker who gains control of a system account could use this to escalate to administrator-level permissions.
