0 CVE-2025-66630 is a critical vulnerability in the GoFiber web framework versions prior to 2.52.11, caused by the use of a cryptographically weak pseudo-random number generator (PRNG) in UUID generation. The issue arises because the underlying crypto/rand package in Go versions before 1.24 can return errors when secure randomness is unavailable, but Fiber's UUID functions do not propagate these errors. This leads to predictable or low-entropy UUIDs being used in security-sensitive middleware components such as sessions, CSRF protection, rate limiting, and request ID generation. Exploitation could allow attackers to predict identifiers, potentially bypassing security controls or causing session fixation. The vulnerability has a CVSS 4.0 score of 9.2 (critical) and is fixed in Fiber version 2. Join the discussion | CVE Database V5 | 02/09/2026, 18:04:47 UTC Added: 02/09/2026, 18:16:17 UTC |
