MediumCVSS 4.3Exploitation Probability (EPSS)
Low risk23th percentile - higher than 23% of all known CVEs
Summary
Improper verification of cryptographic signature in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
Risk Assessment
An attacker may impersonate trusted resources or content, potentially enabling phishing or deceiving users.
Recommendation
Update Microsoft Edge to the latest patched version and enforce browser updates.
