    CVE-2025-66565 (GCVE-0-2025-66565)

    Vulnerability from nvd – Published: 2025-12-09 01:47 – Updated: 2025-12-09 16:03

    Title
    Fiber Utils UUIDv4 and UUID Silent Fallback to Predictable Values
    Summary
    Fiber Utils is a collection of common functions created for Fiber. In versions 2.0.0-rc.3 and below, when the system's cryptographic random number generator (crypto/rand) fails, both functions silently fall back to returning predictable UUID values, including the zero UUID "00000000-0000-0000-0000-000000000000". The vulnerability occurs through two related but distinct failure paths, both ultimately caused by crypto/rand.Read() failures, compromising the security of all Fiber applications using these functions for security-critical operations. This issue is fixed in version 2.0.0-rc.4.
