Missing Authorization vulnerability in Soflyy Breakdance allows Exploiting Incorrectly Configured Access Control Security Levels.

This issue affects Breakdance: from n/a before 2.7.

AnalysisAI

Missing authorization checks in the Breakdance WordPress page builder plugin (all versions before 2.7) allow unauthenticated remote attackers to access protected functionality due to improperly configured access control levels. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) confirms network-reachable exploitation with no credentials required and high confidentiality impact, meaning sensitive data accessible only to authenticated users can be read by anonymous attackers. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.

Technical ContextAI

Breakdance is a visual WordPress page builder plugin developed by Soflyy. The root cause is CWE-862 (Missing Authorization), meaning the plugin fails to perform adequate authorization checks before granting access to one or more protected operations or data endpoints. In WordPress plugin architecture, this typically occurs when REST API routes, admin-ajax handlers, or admin-menu callbacks omit capability checks such as current_user_can() or nonce verification, allowing unauthenticated HTTP requests to reach privileged functionality. The Patchstack advisory references version 2.6.1 as the confirmed vulnerable release, with the fix shipped in version 2.7.

RemediationAI

Update the Breakdance plugin to version 2.7 or later immediately via the WordPress plugin dashboard or by downloading directly from the WordPress plugin repository; this is the vendor-released patch confirmed by the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/breakdance/vulnerability/wordpress-breakdance-plugin-2-6-1-broken-access-control-vulnerability. As an interim compensating control, administrators unable to patch immediately should restrict access to WordPress REST API and admin-ajax endpoints via a web application firewall (WAF) - for example, applying IP allowlist rules to /wp-json/ and /wp-admin/admin-ajax.php - though this may break legitimate front-end functionality that depends on these endpoints and is not a substitute for patching. Deactivating the Breakdance plugin entirely until patching is feasible eliminates the attack surface at the cost of losing page builder functionality.
