Advisories for Golang/Github.com/Gofiber/Utils package

Critical security vulnerabilities exist in both the UUIDv4() and UUID() functions of the github.com/gofiber/utils package. When the system's cryptographic random number generator (crypto/rand) fails, both functions silently fall back to returning predictable UUID values, the zero UUID "00000000-0000-0000-0000-000000000000". This compromises the security of all Fiber applications using these functions for security-critical operations on Go versions prior to 1.24. Both functions are vulnerable to the same root cause (crypto/rand failure): UUIDv4(): …
