Fiber (Go) has a Denial of Service vulnerability (CVE-2026-25882) affecting v2 and v3: routing mismatch with more than 30 parameters can crash the app due to missing validation during route registration and an unbounded array write during request matching. Affected versions are v2 prior to 2.52.1...

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...

Fiber 安全漏洞

Fiber is an open-source web framework written in Go. Versions of Fiber prior to 2.52.12 and 3.1.0 contain security vulnerabilities. These vulnerabilities stem from lack of validation during route registration and unbounded array writes during request matching, which may lead to application crashe...

Fiber 安全漏洞

Fiber is an open-source web framework written in Go language. Versions of Fiber prior to 3.1.0 have a security vulnerability. This vulnerability stems from the fiberflash cookie, which can trigger excessive memory allocation through unvalidated msgpack deserialization, potentially leading to...
