Microsoft’s Patch Tuesday updates for June 2025 include fixes for an actively exploited zero-day vulnerability and nine additional flaws at high risk of exploitation.
In all, the Microsoft Patch Tuesday June 2025 release note included fixes for 68 vulnerabilities, plus three non-Microsoft CVEs affecting Windows Secure Boot and Chromium-based Edge.
The highest-rated vulnerability included in the update – a 9.8-severity Power Automate Elevation of Privilege vulnerability (CVE-2025-47966) – was fixed earlier this month.
Microsoft Patch Tuesday June 2025: Zero-Day, High-risk Flaws
The exploited zero-day – CVE-2025-33053, an 8.8-rated Web Distributed Authoring and Versioning (WebDAV) Remote Code Execution vulnerability – was reported by Check Point researchers, who discovered the flaw being used in an attempted cyberattack against a defense company in Turkey.
In the attack, the advanced persistent threat (APT) group Stealth Falcon used a .url file that exploited the zero-day vulnerability to execute malware from a threat actor-controlled WebDAV server, the researchers said.
The nine vulnerabilities designated “Exploitation More Likely” by Microsoft include:
