Description

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

 - decode-uri-component through 0.4.1 is vulnerable to denial of service. The decode() function splits input
 on '%' producing N tokens and calls decodeComponents(), exhibiting super-linear parsing time: 200 '%ab'
 tokens takes approximately 0.7s, 700 tokens approximately 6s, and 1400 tokens approximately 33s. An
 attacker can cause significant CPU consumption and event-loop blocking via crafted input. (CVE-2026-45822)

Solution

Update the decode-uri-component library and its related packages to version 0.5.0 or later.
