Lifecycle Timeline
2DescriptionCVE.org
The GDPR Cookie Consent plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the gdpr_cookie_consent_ajax_save_schedule_scan() function (the wp_ajax_gcc_save_schedule_scan AJAX action) in versions up to, and including, 4.3.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the plugin's cookie scan schedule configuration stored in the gdpr_scan_schedule_data option, which is an administrative function intended to be limited to users with the manage_options capability.
AnalysisAI
Unauthorized modification of cookie scan schedule configuration in the GDPR Cookie Consent WordPress plugin (versions up to 4.3.6) is achievable by any authenticated subscriber-level user. The vulnerability stems from a dual failure - absent capability check and absent nonce verification - on the wp_ajax_gcc_save_schedule_scan AJAX action, allowing low-privileged users to overwrite the gdpr_scan_schedule_data option that is administratively intended to require manage_options capability. …

Vulnerability AssessmentAI
| Exploitation | Requires an authenticated WordPress session with at minimum Subscriber-level role - the vulnerability is only reachable via the wp_ajax_ AJAX hook, which enforces login. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 3.1 scores this at 4.3 Medium with vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, reflecting a low-privileges requirement and limited integrity impact with no confidentiality or availability consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has registered a free subscriber account on a WordPress site running GDPR Cookie Consent 4.3.6 or earlier sends a crafted POST request to /wp-admin/admin-ajax.php with action=gcc_save_schedule_scan and manipulated schedule parameters. Because the handler performs no capability check and no nonce validation, the request is accepted and the gdpr_scan_schedule_data option is overwritten with attacker-controlled values, disrupting or disabling the site's scheduled cookie compliance scans. … |
| Remediation | Update the GDPR Cookie Consent plugin to version 4.3.7 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
