View online: https://www.drupal.org/sa-contrib-2026-050 Project: Plotly.js Graphing [1] Date: 2026-June-17 Security risk: *Critical* 19 ∕ 25 AC:None/A:User/CI:All/II:All/E:Theoretical/TD:Default [2] Vulnerability: PHP object injection Affected versions: <3.0.2 CVE IDs: CVE-2026-55810 Description: The Plotly.js Graphing module provides a fully customizable implementation of the open source Plotly.js graphing library. The module stores some data as PHP-serialized strings. In some situations, malicious data can be written directly to the field. This can lead to an object injection vulnerability when the data are unserialized. This vulnerability is mitigated by the fact that an attacker must have permission to edit a content entity with an attached plotly_js_graph field. In addition, the core JSON:API module must be enabled with the option "Accept all JSON:API create, read, update, and delete operations", which is not the default, or the attacker needs some other way to edit field values directly. Solution: Install the latest version: * If you use the Plotly.js Graphing module for Drupal, upgrade to plotly_js-3.0.2 [3].
