GHSA-g5vj-wj9x-4jg9: symbiote/silverstripe-multivaluefield Possible PHP Object Injection via Multi-Value Field Extension

A potential deserialisation vulnerability has been identified in the symbiote/silverstripe-multivaluefield which could allow an attacker to exploit implementations of this module via object injection.

Support for handling PHP objects as values in this module has been deprecated, and the serialisation technique has been switched to using JSON for handling arrays.

As well as this, a potential XSS (cross-site scripting) vulnerability has been identified and remediated.

Root Cause Analysis

The vulnerability stems from unsafe unserialize() usage in data handling methods. In versions <3.1.0:

getValue() directly unserialized stored string values without validation
setValue() similarly unserialized input strings This allowed malicious serialized payloads to trigger object instantiation. The 3.1.0 patch introduced JSON serialization and added security checks in restoreValueFromDb(), but prior versions lacked these protections. The commit diff shows removal of direct unserialize calls from these methods, confirming their role in the vulnerability.
