How to fix?

Upgrade spatie/image-optimizer to version 1.7.3 or higher.

Overview

Affected versions of this package are vulnerable to Deserialization of Untrusted Data through the phar:// protocol due to improper input sanitization passed to the file_exists function. Exploiting this vulnerability is possible when the attacker can upload files to the server, and it can lead to remote code execution, especially when ImageOptimizer is used with frameworks with documented POP chains like Laravel/vulnerable developer code.

Details

Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
