Microsoft Active Directory Domain Services Privilege Escalation Vulnerability — An authenticated user could manipulate attributes on computer accounts they own or manage, and acquire a certificate from Active Directory Certificate Services that would allow for privilege escalation to SYSTEM. Listed in the CISA KEV catalog (added 2022-08-18) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~83%. Treat it as real and prioritize remediation over triage.
- 0
Required action for Microsoft Active Directory: Apply updates per vendor instructions. CISA set a federal remediation due date of 2022-09-08. After patching, verify the vulnerable path is no longer reachable before closing the finding.

- CVE-2026-1530HIGH 8.1
A flaw was found in fog-kubevirt. This vulnerability allows a remote attacker to perform a Man-in-the-Middle (MITM) attack due to disabled certificate validation. This enables the attacker to intercept and potentially alter sensitive communications between Satellite and OpenShift, resulting in information disclosure and data integrity compromise.
- CVE-2026-1531HIGH 8.1
A flaw was found in foreman_kubevirt. When configuring the connection to OpenShift, the system disables SSL verification if a Certificate Authority (CA) certificate is not explicitly set. This insecure default allows a remote attacker, capable of intercepting network traffic between Satellite and OpenShift, to perform a Man-in-the-Middle (MITM) attack. Such an attack could lead to the disclosure or alteration of sensitive information.

Improper certificate validation in PKCS7_verify() in AWS-LC allows an unauthenticated user to bypass certificate chain verification when processing PKCS7 objects with multiple signers, except the final signer. Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
