A critical flaw in Microsoft SharePoint has crossed the threshold from known risk to active harm, as the release of public exploit code transformed what was once a sophisticated attacker's tool into something available to anyone willing to look. The vulnerability, CVE-2026-50522, does not merely open a door into a single system — it hands attackers the cryptographic keys that govern trust across entire enterprise networks. In the space between a patch's release and its deployment lies the territory where real damage is done, and that territory is presently occupied.
