SCA: security update for addressable (GHSA-h27x-rffw-24p4)

high Tenable Cloud Security Plugin ID 440012

Description

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

 - Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard
 library. From 2.3.0 to before 2.9.0, within the URI template implementation in Addressable, two classes of
 URI template generate regular expressions vulnerable to catastrophic backtracking. Templates using the *
 (explode) modifier with any expansion operator (e.g., {foo*}, {+var*}, {#var*}, {/var*}, {.var*}, {;var*},
 {?var*}, {&var*}) generate patterns with nested unbounded quantifiers that are O(2^n) when matched against
 a maliciously crafted URI. Templates using multiple variables with the + or # operators (e.g.,
 {+v1,v2,v3}) generate patterns with O(n^k) complexity due to the comma separator being within the matched
 character class, causing ambiguous backtracking across k variables. When matched against a maliciously
 crafted URI, this can result in catastrophic backtracking and uncontrolled resource consumption, leading
 to denial of service. This vulnerability is fixed in 2.9.0. (CVE-2026-35611)

Solution

Update the addressable library and its related packages to version 2.9.0 or later.
