SCA: security update for soupsieve (GHSA-2wc2-fm75-p42x)

high Tenable Self-Hosted Container Security Plugin ID 444552

Description

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

 - Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4. Prior to 2.8.4, the CSS
 selector parser in soupsieve allocates unbounded memory when compiling large comma-separated selector
 lists, allowing an attacker who can supply a crafted selector string to soupsieve.compile() or Beautiful
 Soup .select() / .select_one() to allocate hundreds of megabytes of heap memory from a relatively small
 input and cause denial of service. This issue is fixed in version 2.8.4. (CVE-2026-49476)

Solution

Update the soupsieve library and its related packages to version 2.8.4 or later.
