ManageEngine ADAudit Plus CVSS 10: unauth RCE through the agent API
A perfect-10 RCE in ADAudit Plus tops the list, followed by a 9.9 deserialization bug in M365 Copilot and a 9.8 auth bypass in Appriss VINE that dumps PII. OpenShift AI and a WordPress plugin round things out.
Five new CVEs today, and the top one deserves your full attention. CVE-2026-6516 is a CVSS 10.0 unauthenticated RCE in ManageEngine ADAudit Plus, exploitable over the network through the agent API with zero credentials required. Nobody's reported exploitation in the wild yet, but a perfect 10 with no auth barrier won't stay theoretical for long. If you run ADAudit Plus, patch it right now.
Today's CVEs
Sorted by urgencyCVE-2026-6516
NVDAn attacker can run arbitrary code on your ManageEngine ADAudit Plus server without any credentials at all, through the agent API. CVSS 10.0, no authentication required, network-accessible. If you run ADAudit Plus for Active Directory auditing, this is about as bad as it gets.
- Affected estate
- Anyone running ManageEngine ADAudit Plus versions before 8606
- How to check
- Log into the ADAudit Plus web console and check the version number under Settings > About, or check the installed version in Programs and Features. Anything below 8606 is vulnerable.
- Included because
- unauthenticated; network-accessible; CVSS 10.0; common AD auditing product
- Action
- Upgrade to ADAudit Plus version 8606 or later. If immediate patching isn't possible, restrict network access to the agent API port while you schedule the upgrade.
- Why it matters
- An unauthenticated attacker on your network can get full code execution on the ADAudit Plus server, which typically has privileged access to your Active Directory environment.

CVE-2026-50517
NVDAn authenticated attacker can exploit a deserialization bug in M365 Copilot to execute code over the network. CVSS 9.9. The attacker needs some level of authorization first, but once they have it, they can run code in your M365 Copilot environment. This is a cloud-side vulnerability, so the fix is on Microsoft's end, but you should verify your tenant is updated.
- Affected estate
- Anyone with M365 Copilot enabled in their Microsoft 365 tenant
- How to check
- Check the Microsoft 365 admin center Message Center and Service Health dashboard for advisories related to this CVE. Review your tenant's Copilot license assignments.
- Included because
- CVSS 9.9; deserialization to RCE; widely deployed cloud product
- Action
- Verify the fix is deployed in your tenant via the M365 admin center. Audit Copilot activity logs for signs of exploitation. Consider temporarily restricting Copilot access if the fix isn't confirmed.
- Why it matters
- An authorized user (including a compromised account) can escalate to arbitrary code execution in your M365 Copilot environment.

CVE-2026-63359
NVDThe Appriss Insights (Equifax) VINE victim notification applications have an authentication bypass that lets an unauthenticated attacker skip the login page entirely, steal other users' credentials, take over accounts, and dump sensitive PII from the database. CVSS 9.8. If you operate or integrate with VINE, this is a full compromise scenario with real PII exposure risk.
- Affected estate
- Anyone operating or hosting Appriss Insights (Equifax) VINE applications, and government or criminal justice agencies that integrate with VINE
- How to check
- Identify any VINE application instances in your environment. Check with your vendor contact for the current version and whether the patch has been applied.
- Included because
- unauthenticated; authentication bypass; PII exposure; database dump; CVSS 9.8
- Action
- Apply the vendor-supplied fix. If the fix isn't available yet, take the application offline or restrict public access. Audit database and access logs for unauthorized queries or credential harvesting.
- Why it matters
- Unauthenticated attackers can bypass login, steal credentials, take over accounts, and dump sensitive PII including victim notification data.

CVE-2026-16745
NVDThe web console (odh-dashboard) in Red Hat OpenShift AI binds to the wrong network interface, letting any attacker inside the cluster bypass authentication by passing an arbitrary access token. From there they can impersonate any user, hit the Kubernetes API, run code, and escalate privileges. CVSS 8.8. The attacker needs to already be inside the cluster, so this isn't internet-facing, but any compromised pod or rogue workload can exploit it.
- Affected estate
- Anyone running Red Hat OpenShift AI (RHOAI) with the odh-dashboard component
- How to check
- Run 'oc get pods -n redhat-ods-applications' (or your RHOAI namespace) to confirm odh-dashboard is deployed. Check the image tag or version against Red Hat's advisory to see if you're running a vulnerable build.
- Included because
- authentication bypass; privilege escalation; Kubernetes API access; CVSS 8.8
- Action
- Update the odh-dashboard component to the patched version from Red Hat. Audit Kubernetes API server logs for unusual impersonation or token-based access.
- Why it matters
- Any workload in the cluster can impersonate any user and access the Kubernetes API with full privileges, turning a low-privilege pod compromise into a full cluster takeover.

CVE-2026-25405
NVDThe eRoom WordPress plugin (versions 1.7.1 and earlier) has a SQL injection vulnerability that any user with Contributor-level access can exploit. CVSS 8.5. An attacker needs a low-privilege WordPress account, but once they have one, they can read or modify your database directly. If you allow user registrations or have untrusted Contributors, this is a real risk.
- Affected estate
- WordPress site operators using the eRoom plugin version 1.7.1 or earlier
- How to check
- In the WordPress admin dashboard, go to Plugins and check the eRoom version. Alternatively, check wp-content/plugins/eroom/ for the plugin's readme or version file.
- Included because
- SQL injection; low-privilege authenticated; common CMS platform; CVSS 8.5
- Action
- Update eRoom to the latest version above 1.7.1. If no patched version exists, deactivate and remove the plugin. Audit your WordPress user list for unnecessary Contributor accounts.
- Why it matters
- Any Contributor-level user can run arbitrary SQL queries against your WordPress database, potentially dumping credentials and sensitive data.
