CVE-2026-19396
HighCVSS 7.7Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
A predictable seed in the pseudo-random number generator (PRNG) in the IFTTT pairing token generation of the ASUS RT-BE57 router allows an unauthenticated nearby user to derive the pairing token and read or modify router settings via observed values from an administrator-initiated IFTTT pairing session.
Risk Assessment
An unauthenticated attacker can gain access to router settings and modify them, potentially leading to network security compromise.
Recommendation
Update the ASUS RT-BE57 router firmware and avoid using IFTTT functionality until the patch is applied.
