SCA: security update for saloonphp/saloon (GHSA-f7xc-5852-fj99)

critical Tenable Self-Hosted Container Security Plugin ID 439212

Description

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

 - Saloon is a PHP library that gives users tools to build API integrations and SDKs. Prior to version 4.0.0,
 fixture names were used to build file paths under the configured fixture directory without validation. A
 name containing path segments (e.g. ../traversal or ../../etc/passwd) resulted in a path outside that
 directory. When the application read a fixture (e.g. for mocking) or wrote one (e.g. when recording
 responses), it could read or write files anywhere the process had access. If the fixture name was derived
 from user or attacker-controlled input (e.g. request parameters or config), this constituted a path
 traversal vulnerability and could lead to disclosure of sensitive files or overwriting of critical files.
 The fix in version 4.0.0 adds validation in the fixture layer (rejecting names with /, \, .., or null
 bytes, and restricting to a safe character set) and defense-in-depth in the storage layer (ensuring the
 resolved path remains under the base directory before any read or write). (CVE-2026-33183)

Solution

Update the saloonphp/saloon library and its related packages to version 4.0.0 or later.
