Subscriber Broken Access Control in Fluent Support Pro <= 2.3.1 versions.
AnalysisAI
Broken access control in Fluent Support Pro (WordPress plugin by WP ManageNinja LLC) versions up to and including 2.3.1 permits subscriber-level authenticated users to perform actions restricted to higher-privileged roles. Rooted in CWE-862 (Missing Authorization), the flaw allows the lowest standard WordPress user role - subscribers, often self-registered customers - to invoke plugin functionality without the authorization checks that should gate those actions, resulting in limited confidentiality and integrity impact against support ticket data. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress subscriber-level account on the target installation, as confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.4 Medium is grounded in network-accessible exploitation (AV:N), low attack complexity (AC:L), a required low-privileged subscriber account (PR:L), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality and integrity impact (C:L/I:L) with no availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free subscriber account on a WordPress site running Fluent Support Pro 2.3.1 or earlier - a step requiring no special privileges on sites with open registration. The attacker then sends crafted HTTP requests directly to the plugin's unprotected endpoint, bypassing the authorization check that should restrict access to agent- or admin-level roles, and reads or alters support ticket records. … |
| Remediation | The primary remediation is to update Fluent Support Pro to a version beyond 2.3.1; however, no exact patched release version number is confirmed in the available data - administrators should consult the WP ManageNinja LLC plugin page on the WordPress repository or the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/fluent-support-pro/vulnerability/wordpress-fluent-support-pro-plugin-2-3-1-broken-access-control-vulnerability for patch confirmation before treating any specific version as fixed. … Detailed patch versions, workarounds, and compensating controls in full report. |
