Name of the Vulnerable Software and Affected Versions Fiber versions 3.0.0 and earlier Fiber versions 3.0.0 through 3.0.0 Description A Path Traversal flaw exists in Fiber, potentially allowing a remote attacker to bypass the static middleware sanitizer and read arbitrary files on the server file...

Fiber 路径遍历漏洞

Fiber is an open-source web framework written in Go. Versions of Fiber v3 and earlier have a path traversal vulnerability. This vulnerability arises from the possibility of bypassing the static middleware cleaner, which may lead to the reading of arbitrary files on the Windows server file system...

CVE-2026-25891: Improper Limitation of a Pathname to a Restricted Directory

Fiber is an Express inspired web framework written in Go. A Path Traversal CWE-22 vulnerability in Fiber allows a remote attacker to bypass the static middleware sanitizer and read arbitrary files on the server file system on Windows. This affects Fiber v3 through version 3.0.0. This has been...

CVE-2026-25899: Memory Allocation with Excessive Size Value

Fiber is an Express inspired web framework written in Go. In versions on the v3 branch prior to 3.1.0, the use of the fiberflash cookie can force an unbounded allocation on any server. A crafted 10-character cookie value triggers an attempt to allocate up to 85GB of memory via unvalidated msgpack...

CVE-2025-66630

A flaw was found in the Fiber web framework github.com/gofiber/fiber/v2. On Go versions prior to 1.24, the framework's Universally Unique Identifier UUID generation functions do not return an error when the underlying cryptographic randomness source fails. This can cause applications to use...

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...
