- **CVSS Score:** Recorded Future Risk Scores up to **99 (Very Critical)**.
- **CWE:** Includes Deserialization allowlist bypass (Log4j), Remote Code Execution (RCE), and Insecure Deserialization.
## Affected Systems
- **Products:**
- **Print Management:** PaperCut NG/MF
- **AI/DevOps:** Ray-Project Ray, IBM Langflow, MLflow
- **Virtualization:** Broadcom VMware vCenter
- **Collaboration/CI-CD:** JetBrains TeamCity, Gitea, Microsoft SharePoint
- **Network Edge:** Cisco ASA/FTD, Oracle HTTP Server
- **Databases/Analytics:** Metabase, Microsoft SQL Server
- **Versions:** Specific versions vary by CVE; notably PaperCut, Ray, and Metabase require immediate attention.
- **Configurations:** Systems running internet-facing instances of AI development tools (Ray, Langflow) and remote management interfaces.
## Vulnerability Description
The August 2026 landscape is dominated by **Remote Code Execution (RCE)** flaws. Significant technical issues include:
- **Deserialization Bypasses:** Found in Apache Log4j (hardening gap) and Ajax.NET.
- **AI Infrastructure Flaws:** Vulnerabilities in Ray and IBM Langflow allow attackers to execute code via the application's processing of untrusted input.
- **Legacy Exploitation:** Continued weaponization of older flaws in Microsoft Office (CVE-2017-0199) and the Linux Kernel (DirtyPipe).
## Exploitation
- **Status:** **Exploited in the wild.** All 70+ vulnerabilities listed were actively exploited or operationally weaponized in August 2026.
- **Complexity:** Low to Medium for most RCE-based flaws.
- **Attack Vector:** Primarily **Network** (Remote).
- **PoC Availability:** Public PoCs are available for most high-profile CVEs, including PaperCut, Ray, Metabase, and VMware vCenter.
## Impact
- **Confidentiality:** Very High (Full data exfiltration possible via RCE).
- **Integrity:** Very High (System manipulation and unauthorized changes).
- **Availability:** Very High (Potential for ransomware or system destruction).
## Remediation
### Patches
- **PaperCut:** Upgrade to latest patched versions for NG/MF.
- **VMware:** Apply Broadcom updates for vCenter CVE-2026-59310.
- **Ray-Project:** Update to version 2.40.0 or later for CVE-2025-62593.
- **Microsoft:** Apply August 2026 Cumulative Updates (covers 11% of the monthly volume).
### Workarounds
- Discontinue use of exposed AI dashboards (Ray, Metabase) on the public internet.
- Implement network segmentation for RMM and virtualization management interfaces.
## Detection
- **Indicators of Compromise:** Look for unusual outbound traffic from AI frameworks and unexpected administrative logins on PaperCut servers.
- **Detection Methods:**
- **Nuclei Templates:** Available for CVE-2025-62593 (Ray), CVE-2026-72898 (Metabase), and CVE-2026-9198 (IBM Langflow).
- **CISA KEV:** 31 of these vulnerabilities are tracked on CISA’s Known Exploited Vulnerabilities catalog.
