The November 2026 Security Update Review
November 2026 brings substantial patches from both Microsoft and Adobe, with Adobe addressing 110 CVEs across nine products. The most critical Adobe patch is for Connect, fixing 24 CVEs, 18 of which are critical with a CVSS score of 10.0, requiring immediate attention. The Experience Manager also received a critical update, addressing 14 CVEs, including four critical bugs with a CVSS of 9.9. All other Adobe patches this month are Deployment Priority 3, with none reported as publicly known or under active exploit.Microsoft released approximately 1,090 new CVEs, a significant but slightly lower count than the previous month. Only one Microsoft bug, CVE-2026-124194, a Microsoft Outlook Spoofing Vulnerability, is under active attack. Despite its "spoofing" label and moderate CVSS of 6.5, this vulnerability can disclose NTLMv2 hashes, enabling attacker authentication.Other notable Microsoft patches include CVE-2026-116928, a Windows Search RCE vulnerability reachable via Exchange Server, rated CVSS 9.8. CVE-2026-119958 addresses a critical Windows LDAP RCE vulnerability exploitable without authentication, potentially devastating on Domain Controllers. Azure OpenAI also received an Elevation of Privilege patch, CVE-2026-119990, raising concerns due to the lack of customer guidance.Additional critical Microsoft vulnerabilities include CVE-2026-119952 in Windows Schannel, a Remote Code Execution bug with high exploitation likelihood, and CVE-2026-95962 in Windows Virtual Filtering Platform (VFP), a use-after-free RCE. An Xbox Live Networking Service RCE, CVE-2026-112967, also rated CVSS 9.8, stands out due to its unusual target.Finally, 30 of the November Microsoft CVEs are identified as "wormable," allowing unauthenticated remote code execution without user interaction. These include multiple vulnerabilities in Message Queuing, DNS, Color Management, DHCP Server, DirectMusic, and Xbox, as well as single instances in Exchange Server, LDAP, Schannel, and IIS, among others.
