Not one of the weaknesses addressed this month are recognized to be actively exploited, however 14 of the failings earned Microsoft’s most-dire “crucial” ranking, that means they could possibly be exploited to grab management over weak Home windows PCs with little or no assist from customers.
Whereas not listed as crucial, CVE-2025-49719 is a publicly disclosed data disclosure vulnerability, with all variations way back to SQL Server 2016 receiving patches. Microsoft charges CVE-2025-49719 as much less prone to be exploited, however the availability of proof-of-concept code for this flaw means its patch ought to in all probability be a precedence for affected enterprises.

Adam Barnett at Rapid7 notes that at present is the tip of the street for SQL Server 2012, that means there might be no future safety patches even for crucial vulnerabilities, even should you’re keen to pay Microsoft for the privilege.
Barnett additionally known as consideration to CVE-2025-47981, a vulnerability with a CVSS rating of 9.8 (10 being the worst), a distant code execution bug in the best way Home windows servers and shoppers negotiate to find mutually supported authentication mechanisms. This pre-authentication vulnerability impacts any Home windows consumer machine working Home windows 10 1607 or above, and all present variations of Home windows Server. Microsoft considers it extra seemingly that attackers will exploit this flaw.
Microsoft additionally patched at the very least 4 crucial, distant code execution flaws in Workplace (CVE-2025-49695, CVE-2025-49696, CVE-2025-49697, CVE-2025-49702). The primary two are each rated by Microsoft as having the next probability of exploitation, don’t require person interplay, and may be triggered via the Preview Pane.

“Exploiting this vulnerability permits an attacker to execute arbitrary SQL queries because the privileged SMS service account in Microsoft Configuration Supervisor,” Hopkins stated. “This entry can be utilized to control deployments, push malicious software program or scripts to all managed units, alter configurations, steal delicate knowledge, and doubtlessly escalate to full working system code execution throughout the enterprise, giving the attacker broad management over the complete IT setting.”
Individually, Adobe has launched safety updates for a broad vary of software program, together with After Results, Adobe Audition, Illustrator, FrameMaker, and ColdFusion.
The SANS Web Storm Heart has a breakdown of every particular person patch, listed by severity. If you happen to’re liable for administering a lot of Home windows methods, it could be price maintaining a tally of AskWoody for the lowdown on any doubtlessly wonky updates (contemplating the big variety of vulnerabilities and Home windows parts addressed this month).
If you happen to’re a Home windows dwelling person, please contemplate backing up your knowledge and/or drive earlier than putting in any patches, and drop a be aware within the feedback should you encounter any issues with these updates.
