handcraftedinthealps/goodby-csv fixed: 1.4.3 
Upgrade handcraftedinthealps/goodby-csv to 1.4.3
Verify Direct and Transitive Dependencies

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

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-49597, inspect your project dependencies for Handcraftedinthealps/goodby csv:

inspect dependencies for handcraftedinthealps/goodby-csv

Analyze the terminal output to locate any version of Handcraftedinthealps/goodby csv in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.3), 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 CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes, where the product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified. In Handcraftedinthealps/goodby csv, 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

### Impact goodby-csv could be used as part of a chain of methods that is exploitable when an insecure deserialization vulnerability exists in an application. This so-called "gadget chain" presents no direct threat but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability. ### Patches Has the problem been patched? What versions should users upgrade to? The problem is patched with Version 1.4.3 ### Workarounds Patch `src/Goodby/CSV/Export/Standard/Collection /CallbackCollection.php`: ```diff + public function __wakeup() { + throw new \BadMethodCallException('Cannot unserialize ' . __CLASS__); + } ``` However, this is not directly exploitable; a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize(). There are no such known exploits in goodby-csv. ### References _Are there any links users can visit to find out more?_
