CVE-2026-87697
HighCVSS 8.8Exploitation Probability (EPSS)
Elevated risk57th percentile - higher than 57% of all known CVEs
Summary
Deserialization of untrusted data in .NET allows an unauthorized attacker to execute code over a network.
Risk Assessment
A remote attacker could execute arbitrary code on the server, potentially leading to full system compromise.
Recommendation
Install the latest .NET security updates and restrict access to network services.
