CVE-2026-3416

CVE-2026-3416 affects the API Publisher component in multiple WSO2 products. The root cause is the use of a non-cryptographic pseudorandom number generator (PRNG) to create shared secrets for Webhook HMAC validation. Because the PRNG lacks sufficient entropy, a sophisticated attacker with high at...

CVE-2026-3416 Predictable Pseudorandom Number Generation via Webhook HMAC Secret Generation in Multiple WSO2 Products Allows Forged Event Payloads

The API Publisher component previously used a non-cryptographic pseudorandom number generator PRNG to create shared secrets for Webhook HMAC validation. This PRNG lacks sufficient entropy for security-sensitive operations, allowing a sophisticated attacker to predict future secrets. This enables...
