// Deep technical intelligence on the highest-severity known-exploited vulnerabilities
We cover only Critical and High-severity vulnerabilities from the CISA Known Exploited Vulnerabilities catalogue — confirmed active threats with CVSS 7.0 or above. Each analysis breaks down the exploit mechanism, real-world attack campaigns, and concrete remediation steps so your team can act fast.
ConnectWise — ScreenConnect
A path traversal vulnerability in ConnectWise ScreenConnect enables unauthenticated remote code execution, exploited extensively in ransomware campaigns targeting managed service providers.
Palo Alto Networks — PAN-OS
An out-of-bounds write vulnerability in PAN-OS's Captive Portal and User-ID service allows unauthenticated remote code execution as root on PA-Series and VM-Series firewalls.
Linux — Linux Kernel
An incorrect resource transfer between security domains in the Linux kernel allows a local unprivileged user to escalate to root privileges, affecting a broad range of distributions.
Cisco — Catalyst SD-WAN Controller & Manager
Authentication bypass in Cisco Catalyst SD-WAN Manager and Controller allows unauthenticated remote attackers to gain full administrative privileges without credentials.
BerriAI — LiteLLM
A SQL injection vulnerability in BerriAI LiteLLM allows authenticated attackers to read and modify the proxy database, exposing stored API keys for OpenAI, Anthropic, and other LLM providers.
WebPros — cPanel & WHM
An authentication bypass vulnerability in cPanel & WHM's login flow grants unauthenticated attackers full control panel access, affecting millions of web hosting deployments worldwide.
Vuln Brief provides authoritative technical analysis of Critical and High-severity vulnerabilities from the CISA Known Exploited Vulnerabilities (KEV) catalogue — the definitive list of CVEs actively exploited in the wild.
We focus exclusively on CVSS 7.0+ entries — the vulnerabilities that represent the highest real-world risk to organisations. Each article goes beyond the NVD description, examining the exploit mechanism, affected code paths, real-world attack campaigns, and concrete remediation steps.
Coverage spans high-priority targets: enterprise network infrastructure, endpoint management, cloud-adjacent systems, and developer tooling — wherever Critical and High KEVs are actively exploited.
We cover only CVSS 7.0+ entries from the CISA KEV catalogue — confirmed active exploitation, highest real-world risk, no noise from lower-severity entries.
We cover exploit mechanisms, vulnerable code paths, CVSS breakdowns, and detection indicators — not just vendor advisories.
Every article includes patch guidance, version ranges, and interim mitigations for when immediate patching isn't possible.
