CVE-2025-14454: 
WordPress vulnerability analysis and mitigation

CVE-2025-14454 is a Cross-Site Request Forgery (CSRF) vulnerability in the Image Slider by Ays – Responsive Slider and Carousel plugin for WordPress. It affects all versions up to and including 2.7.0, and stems from missing or incorrect nonce validation on the plugin's bulk delete functionality. An unauthenticated attacker can delete arbitrary sliders by tricking a logged-in site administrator into clicking a malicious link. It was published on December 13, 2025, with a CVSS v3.1 base score of 4.3 (Medium) (Wordfence, Red Hat CVE).

The root cause is classified as CWE-352 (Cross-Site Request Forgery), arising from the absence of proper WordPress nonce validation in the bulk delete handler within class-ays-slider-list-table.php (around line 430). Because the action does not verify that the request originates from a legitimate, authenticated session, an attacker can craft a forged HTTP request that, when triggered by an administrator's browser, causes the server to execute the bulk delete operation without the user's intent. Exploitation requires social engineering — the attacker must lure an authenticated administrator to visit a malicious page or click a crafted link. The vulnerable code path is publicly visible in the plugin's SVN repository (WordPress Trac, ENISA EUVD).

Successful exploitation allows an unauthenticated attacker (acting through a tricked administrator) to permanently delete arbitrary image sliders configured in the WordPress plugin, resulting in data loss and potential site disruption. The impact is limited to integrity (slider content deletion) with no confidentiality or availability impact beyond the loss of slider data. There is no evidence of lateral movement potential or sensitive data exposure associated with this vulnerability (Wordfence, ENISA EUVD).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for CVE-2025-14454. The EPSS score is approximately 0.012% (0.000120), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires user interaction (an administrator must be tricked into triggering the forged request), which further limits practical exploitability (Wordfence, Red Hat CVE).

1. Reconnaissance: Identify WordPress sites running the "Image Slider by Ays" plugin at version 2.7.0 or earlier (e.g., via WPScan or by inspecting plugin metadata in page source).
2. Craft forged request: Construct a malicious HTML page or link that submits a POST (or GET) request to the target WordPress admin endpoint for the plugin's bulk delete action, including the required action parameter (e.g., action=bulk_delete) but without a valid nonce.
3. Social engineering: Deliver the malicious link or page to a logged-in site administrator via phishing email, forum post, or other means, inducing them to click the link or visit the page while authenticated to the WordPress admin panel.
4. Trigger deletion: The administrator's browser automatically sends the forged request with their session cookies, causing the server to process the bulk delete operation and remove the targeted sliders without the administrator's intent (Wordfence, WordPress Trac).

• Logs: WordPress admin access logs showing unexpected POST requests to wp-admin/admin.php or wp-admin/edit.php with parameters indicating bulk delete actions (e.g., action=bulk_delete, action2=bulk_delete) for the ays-slider plugin from unusual referrers or external origins.
• Application: Unexplained disappearance of image sliders in the WordPress admin dashboard without corresponding administrator activity in audit logs.
• Network: Requests to WordPress admin endpoints originating from unexpected IP addresses or referrer headers pointing to external/unknown domains.

The vendor (ays-pro) released version 2.7.1 of the Image Slider by Ays plugin, which addresses the missing nonce validation in the bulk delete functionality. Site administrators should update to version 2.7.1 or later immediately via the WordPress plugin dashboard. No configuration-based workaround is available; upgrading is the only effective remediation (WordPress Trac Changeset, Wordfence).

The vulnerability was discovered and reported by Wordfence, which published the advisory on December 13, 2025. Coverage has been limited to automated vulnerability aggregators and security feeds (VulDB, Vulners, CIRCL, ENISA EUVD), with no notable researcher commentary or significant social media discussion beyond routine CVE tracking (Wordfence, ENISA EUVD).
