Drupal · Tealium Iq Tag Management · CVE-2026-13244
**Name of the Vulnerable Software and Affected Versions**
Tealium iQ Tag Management versions 0.0.0 through 2.4.0
**Description**
Improperly controlled modification of dynamically-determined object attributes in the Tealium iQ Tag Management module allows for Object Injection. This occurs because the `tealiumiq` field stores data as PHP-serialized strings; if malicious data is written to this field, it can be executed when the data is unserialized. Exploitation requires the attacker to have permissions to edit a content entity with an attached `tealiumiq` field. Additionally, the core `jsonapi` module must be enabled with the option "Accept all JSON:API create, read, update, and delete operations", or the attacker must have an alternative method to edit field values directly.
**Recommendations**
Update Tealium iQ Tag Management to a version later than 2.4.0.
Restrict permissions to edit content entities containing the `tealiumiq` field.
Disable the "Accept all JSON:API create, read, update, and delete operations" option in the `jsonapi` module.
