Lifecycle Timeline
3DescriptionCVE.org
The DataPress (Dataverse Integration) WordPress plugin before 2.91 does not properly restrict access to its template rendering feature and exposes the viewing user's data to it, allowing users with a role as low as Contributor to disclose sensitive information, such as the session cookies of higher privileged users who view the affected content.
AnalysisAI
Session cookie theft in the DataPress (Dataverse Integration) WordPress plugin before 2.91 allows any Contributor-level user to steal session credentials from higher-privileged users such as Editors or Administrators. The plugin's template rendering feature improperly exposes the session data of users who view affected content, enabling privilege escalation via session hijacking. No public exploit code has been identified at time of analysis, but the low barrier to entry (Contributor role) makes this a realistic insider or compromised-low-privilege-account threat against WordPress sites using this plugin.
Technical ContextAI
The DataPress (Dataverse Integration) plugin integrates WordPress with Microsoft Dataverse and exposes a server-side template rendering feature. The root cause is an access control failure: the plugin permits users with the Contributor role to invoke this template rendering functionality, and the rendering context improperly includes or exposes session-level data belonging to the user who views the rendered output. This is architecturally similar to a stored template injection or server-side rendering misconfiguration, where attacker-controlled template input is evaluated in a context that leaks privileged session tokens. No CWE was formally assigned, but the pattern aligns with CWE-200 (Exposure of Sensitive Information) and CWE-284 (Improper Access Control). Affected product confirmed via EUVD-2026-54298: DataPress (Dataverse Integration) versions from 0 up to but not including 2.91.
RemediationAI
The primary fix is to upgrade the DataPress (Dataverse Integration) WordPress plugin to version 2.91 or later, which resolves the improper access restriction on the template rendering feature. The vendor patch is confirmed available; see the WPScan advisory at https://wpscan.com/vulnerability/3b3ab347-a8bd-4baa-8eba-c45a8a79e33f/ for details. If immediate patching is not possible, a compensating control is to revoke Contributor-level access to any DataPress template rendering functionality via role management - note this may break legitimate content workflows for Contributor accounts that rely on the feature. Additionally, site administrators should audit existing Contributor-authored content for suspicious template payloads and rotate session credentials for any privileged accounts that may have viewed affected content prior to patching.
