Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Overview Affected versions of this package are vulnerable to Use of Cryptographically Weak Pseudo-Random Number Generator PRNG due to the UUIDv4 and UUID functions silently returning predictable values, such as the zero UUID, when the cryptographic random number generator fails. An attacker can...

CVE-2025-66565

Fiber Utils (github.com/gofiber/utils) has a vulnerability in UUIDv4() and UUID() where crypto/rand.Read() failures trigger silent fallbacks to predictable UUID values, including the zero UUID 00000000-0000-0000-0000-000000000000. This root cause affects versions up to 2.0.0-rc.3; the issue is fi...
