Authenticated PHP object injection via serialized field
Published Jul 10, 2026 · Updated Jul 10, 2026
PHP object injection in Drupal Tealium iQ Tag Management before 2.4.0 allows remote authenticated users to inject objects through entity fields. The module accepts attacker-controlled serialized data in an attached tealiumiq field and later passes that value to PHP deserialization. Exploitation requires permission to edit the content entity plus non-default unrestricted JSON:API writes, or another direct field-write path.
