Attack Chain

1. The attacker identifies a WordPress site using a vulnerable version of the Ditty plugin (<=3.1.65).
2. The attacker crafts an HTTP POST request targeting the wp-admin/admin-ajax.php endpoint.
3. The POST request includes the action parameter set to ditty_init.
4. The request includes the ditty_id parameter, where the attacker enumerates integer values to guess valid Ditty post IDs.
5. The init_ajax() function in the Ditty plugin processes the request without properly checking the ‘publish’ post status of the requested Ditty.
6. The plugin retrieves the full item content of the Ditty, regardless of its intended visibility (draft, pending, scheduled, or disabled).
7. The plugin returns the full Ditty content in the HTTP response to the attacker.
8. The attacker obtains unauthorized access to content meant to be restricted from public view, potentially including sensitive information or proprietary data.

Impact

Successful exploitation of CVE-2026-9011 allows unauthenticated attackers to bypass intended access controls and retrieve the full content of non-public Dittys within a WordPress site. This can lead to the exposure of sensitive information, proprietary content, or confidential drafts that administrators have explicitly withheld from public view. The number of affected websites is dependent on the adoption rate of the vulnerable Ditty plugin version. If exploited, sensitive data stored within the Ditty plugin could be compromised, resulting in potential data breaches or reputational damage.

Recommendation

• Upgrade the Ditty – Responsive News Tickers, Sliders, and Lists plugin to the latest version (greater than 3.1.65) to patch CVE-2026-9011.
• Deploy the Sigma rule “Detect CVE-2026-9011 Ditty Plugin Unauthorized Access via AJAX” to monitor for exploitation attempts against the ditty_init AJAX endpoint.
• Review and restrict access to sensitive content within Ditty plugins until the patch is applied.
