CVE-2026-86842: CWE-862 Missing Authorization in Real3D Flipbook
The Real3D Flipbook WordPress plugin before 5.4 does not perform capability checks on several of its authenticated flipbook management actions, allowing users with Author-level access and above to delete other users' flipbook content and overwrite administrator-only global settings, which can be leveraged to store JavaScript that executes in the context of any visitor or administrator viewing the site.
AI Analysis
Technical Summary
CVE-2026-86842 is a missing authorization vulnerability (CWE-862) in the Real3D Flipbook WordPress plugin prior to version 5.4. The plugin fails to verify user capabilities on certain flipbook management functions, permitting users with Author-level privileges or above to manipulate other users' flipbook content and modify administrator-only global settings. This can be leveraged to store malicious JavaScript, resulting in cross-site scripting (CWE-79) attacks that execute in the context of site visitors or administrators.
Potential Impact
Users with Author-level access or higher can delete other users' flipbook content and overwrite administrator-only global settings. This unauthorized modification can lead to stored cross-site scripting attacks, allowing execution of arbitrary JavaScript in the context of any visitor or administrator, potentially compromising site integrity and user security.
Mitigation Recommendations
A fix is available in Real3D Flipbook version 5.4. Users should upgrade to version 5.4 or later to ensure proper authorization checks are enforced. Until upgraded, restrict user roles to trusted individuals and monitor for unauthorized changes. Patch status is confirmed by the versioning information indicating versions prior to 5.4 are affected.
