Impact
Successful exploitation could allow an attacker to execute arbitrary code on the affected SharePoint server, potentially leading to full system compromise depending on the privileges of the SharePoint service account. The exact impact depends on the environment and configuration but is generally considered medium severity as per the source. No known active exploitation in the wild is reported.
Summary
The threat involves SharePoint vulnerabilities collectively referenced by CVE-2026-58644, CVE-2026-45659, and CVE-2026-50522. A publicly shared PowerShell PoC script demonstrates exploitation by crafting a malicious security context token that leverages a TypeConfuseDelegate gadget to execute arbitrary commands remotely. The exploit sends a specially crafted WS-Trust request to the SharePoint '_trust/default.aspx' endpoint, potentially enabling remote code execution. The source does not provide vendor advisories or patch information.
