NewCVE-2025-49597 (opens in a new tab)How to fix?
Upgrade handcraftedinthealps/goodby-csv to version 1.4.3 or higher.
Overview
handcraftedinthealps/goodby-csv is a CSV import/export library
Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the __wakeup process. An attacker can execute arbitrary code by leveraging a gadget chain if untrusted data is deserialized by the application.
Note: This is only exploitable if the application deserializes untrusted data due to another vulnerability.
Workaround
This vulnerability can be mitigated by patching the src/Goodby/CSV/Export/Standard/Collection/CallbackCollection.php file to throw an exception in the __wakeup method.
