Critical CVSS 9.6
CVE-2026-20318
NVD analysis in progress
As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Secure Workload engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-20318 are related to improper input validation issues that are grouped under the Common Weakness Enumeration (CWE) CWE-20.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- The application accepts input without checking it, opening the door to unintended behaviour.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
