SCA: security update for granian (GHSA-f5p7-9fr5-8jmj)

medium Tenable Self-Hosted Container Security Plugin ID 441312

Description

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

 - Granian is a Rust HTTP server for Python applications. From 0.2.0 to 2.7.4, Granian aborts a worker
 process if a WSGI application returns an invalid HTTP response header name or value. The WSGI response
 conversion path uses .unwrap() on both the header name and header value constructors, so malformed output
 from the application becomes a process abort instead of a handled error. This vulnerability is fixed in
 2.7.4. (CVE-2026-42545)

Solution

Update the granian library and its related packages to version 2.7.4 or later.
