CyberRota Analysis
AI-GeneratedConcrete CMS versions 9 through 9.5.3 are vulnerable due to inadequate validation of board instance permissions, allowing authenticated users with edit access to retrieve summary information from pages they should not have access to. This could lead to unauthorized exposure of sensitive content, impacting user privacy and data security. Organizations using affected versions should prioritize remediation, especially those with multiple board instances and varying user permissions.
Original NVD Description
Concrete CMS 9 through 9.5.3 did not confirm that a board InstanceItem submitted to the custom-slot preview endpoint belonged to the board instance the requesting user was authorized to edit, and did not enforce page-view permission before generating page-backed summary content. As a result, an authenticated user holding edit-board-contents permission on a single board instance could submit the identifier of an item belonging to a different board instance and receive summary fields, including the page title and description, of an underlying page the same user was otherwise forbidden to view. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.3 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N. Thanks Pakung for reporting.
