SCA: security update for KnpLabs/knp-snappy (GHSA-vpr4-p6fq-85jc)

high Tenable Cloud Security Plugin ID 442285

Description

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

 - Snappy is a PHP library allowing thumbnail, snapshot or PDF generation from a url or a html page. Prior to
 version 1.7.1, on POSIX, escapeshellarg(‘/usr/bin/wkhtmltopdf’) returns the literal string
 ‘/usr/bin/wkhtmltopdf’ with the single-quote characters included. is_executable() then looks for a file
 whose actual name contains those quote characters, which essentially never exists. The safe branch is dead
 code and $command always falls through to the raw, unescaped value. The rest of the arguments (options,
 input, output) are escaped correctly, so injection has to land in the binary string itself. That happens
 whenever the binary path is sourced from configuration that is user-influenced, derived from environment
 variables that ultimately come from request data, or concatenated with any user-controlled fragment. This
 issue has been patched in version 1.7.1. (CVE-2026-46643)

Solution

Update the KnpLabs/knp-snappy library and its related packages to version 1.7.1 or later.
