high Tenable Self-Hosted Container Security Plugin ID 437994

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. In versions on the v3 branch prior to 3.1.0, the
 use of the `fiber_flash` 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 deserialization.
 No authentication is required. Every GoFiber v3 endpoint is affected regardless of whether the application
 uses flash messages. Version 3.1.0 fixes the issue. (CVE-2026-25899)
