It might hardly be a correct Patch Tuesday with out a minimum of one crucial Microsoft Workplace exploit, and this month doesn’t disappoint. CVE-2026-26113 and CVE-2026-26110 are each distant code execution flaws that may be triggered simply by viewing a booby-trapped message within the Preview Pane.
Satnam Narang at Tenable notes that simply over half (55%) of all Patch Tuesday CVEs this month are privilege escalation bugs, and of these, a half dozen had been rated “exploitation extra probably” — throughout Home windows Graphics Part, Home windows Accessibility Infrastructure, Home windows Kernel, Home windows SMB Server and Winlogon. These embrace:
–CVE-2026-24291: Incorrect permission assignments throughout the Home windows Accessibility Infrastructure to succeed in SYSTEM (CVSS 7.8)

However McCarthy says it’s notable as one of many first vulnerabilities recognized by an AI agent and formally acknowledged with a CVE attributed to the Home windows working system. It was found by XBOW, a completely autonomous AI penetration testing agent.
XBOW has persistently ranked at or close to the highest of the Hacker One bug bounty leaderboard for the previous yr. McCarthy stated CVE-2026-21536 demonstrates how AI brokers can determine crucial 9.8-rated vulnerabilities with out entry to supply code.
“Though Microsoft has already patched and mitigated the vulnerability, it highlights a shift towards AI-driven discovery of complicated vulnerabilities at rising pace,” McCarthy stated. “This growth suggests AI-assisted vulnerability analysis will play a rising position within the safety panorama.”
Microsoft earlier supplied patches to handle 9 browser vulnerabilities, which aren’t included within the Patch Tuesday depend above. As well as, Microsoft issued a vital out-of-band (emergency) replace on March 2 for Home windows Server 2022 to handle a certificates renewal challenge with passwordless authentication expertise Home windows Hi there for Enterprise.
