typo3/flow fixed: 1.0.4 
Upgrade typo3/flow to 1.0.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for typo3/flow

How to Check if You Are Affected

To determine whether your application is affected by GHSA-m2hp-5x78-74mg, inspect your project dependencies for Typo3/flow:

inspect dependencies for typo3/flow

Analyze the terminal output to locate any version of Typo3/flow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Typo3/flow, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Due to a missing signature (HMAC) for a request argument, an attacker could unserialize arbitrary objects within FLOW3. To our knowledge it is neither possible to inject code through this vulnerability, nor are there exploitable objects within the FLOW3 Base Distribution. However, there might be exploitable objects within user applications.
