SCA: security update for github.com/gofiber/fiber/v2 (GHSA-g5jq-qmqr-qrwf)

medium Tenable Cloud Security Plugin ID 478104

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Fiber is an Express inspired web framework written in Go. From 2.52.1 until 2.52.3, the CORS middleware's
 validateDomain wildcard matcher in middleware/cors/utils.go strips the scheme and checks only a host
 suffix without requiring a dot boundary. An application configured with a wildcard-subdomain AllowOrigins
 value and AllowCredentials enabled can reflect an unrelated attacker-controlled origin whose host merely
 ends with the configured base domain. A user who visits that origin can expose authenticated cross-origin
 responses to the attacker's page; empty-label origins and later comma-space parsing hardening are outside
 this advisory. This issue is fixed in version 2.52.3. (CVE-2026-119285)

Solution

Update the github.com/gofiber/fiber/v2 library and its related packages to version 2.52.3 or later.
