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:
+ 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.
