SCA: security update for league/flysystem (GHSA-cxf4-7mrp-vvpr)

low Tenable Self-Hosted Container Security Plugin ID 448472

Description

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

 - Flysystem is an open source file storage library for PHP. Prior to 3.35.3, the default
 WhitespacePathNormalizer in src/WhitespacePathNormalizer.php used by Filesystem across adapters calls
 preg_match with the u modifier and treats both false and 0 as falsy. A path containing malformed UTF-8
 causes PCRE to return false, so paths that also contain control characters bypass
 CorruptedPathDetected::forPath() in normalizePath(). Filesystem::write() can store such names and
 Filesystem::listContents() can return the raw ANSI escape sequences, allowing hidden or spoofed terminal
 file listings when an administrator displays them. This issue is fixed in version 3.35.3.
 (CVE-2026-102601)

Solution

Update the league/flysystem library and its related packages to version 3.35.3 or later.
