CVE-2025-30983: Card Flip Image Slideshow XSS Vulnerability

CVE-2025-30983 Overview

CVE-2025-30983 is a DOM-based Cross-Site Scripting (XSS) vulnerability in the gopiplus Card flip image slideshow WordPress plugin (card-flip-image-slideshow). The flaw affects all versions up to and including 1.5. It stems from improper neutralization of user-supplied input during web page generation, classified as [CWE-79]. An authenticated attacker with low privileges can inject malicious script that executes in the browsers of users interacting with the affected page. Successful exploitation requires user interaction and can result in scope-changing impact on confidentiality, integrity, and availability.

Critical Impact
Attackers can execute arbitrary JavaScript in a victim's browser session, enabling session hijacking, credential theft, and unauthorized actions on the affected WordPress site.

Affected Products

gopiplus Card flip image slideshow WordPress plugin (card-flip-image-slideshow)
All plugin versions from n/a through 1.5
WordPress sites with the vulnerable plugin installed and activated

Technical Details for CVE-2025-30983

Vulnerability Analysis

The vulnerability is a DOM-based XSS flaw in the Card flip image slideshow plugin for WordPress. The plugin fails to properly sanitize or encode user-controlled input before writing it into the Document Object Model (DOM). Attackers can craft input that, once processed by client-side JavaScript, is interpreted as executable script rather than inert data.

Exploitation requires an authenticated user with at least contributor-level privileges to submit malicious payloads. A victim must then interact with the affected page for the payload to trigger. Because the vulnerability changes scope, injected script can affect resources beyond the vulnerable component, including administrative sessions.

Root Cause

The root cause is missing input neutralization on data reflected into the DOM by the plugin's client-side rendering logic. Instead of encoding characters such as <, >, and quotes, the plugin writes attacker-controlled values directly into HTML sinks. This allows script tags, event handlers, and JavaScript URI schemes to execute within the page context.

Attack Vector

The attack is delivered over the network and requires low privileges plus user interaction. An attacker stores a crafted payload through the plugin's input fields. When an administrator or another site user loads the affected view, the client-side code renders the payload as HTML, and the browser executes the embedded JavaScript. Refer to the Patchstack WordPress Vulnerability Advisory for advisory details.

Detection Methods for CVE-2025-30983

Indicators of Compromise

Unexpected <script> tags, on* event handlers, or javascript: URIs stored in plugin configuration fields or slideshow entries within the WordPress database.
Outbound browser requests from administrator sessions to attacker-controlled domains shortly after loading pages that render the plugin.
New or modified WordPress administrator accounts created without a corresponding audit trail.

Detection Strategies

Audit wp_options and plugin-specific tables for HTML or JavaScript content in fields expected to hold plain text or image metadata.
Deploy a Web Application Firewall (WAF) rule set that inspects POST requests to plugin endpoints for XSS payload signatures.
Enable and review WordPress activity logs for contributor or author-level accounts creating or editing slideshow content.

Monitoring Recommendations

Monitor authenticated user sessions for anomalous DOM modifications and unexpected script execution using browser-side telemetry or Content Security Policy (CSP) violation reports.
Track plugin version inventory across WordPress deployments to identify hosts still running card-flip-image-slideshow version 1.5 or earlier.
Alert on privilege escalation events and administrative actions performed shortly after low-privileged accounts edit plugin content.

How to Mitigate CVE-2025-30983

Immediate Actions Required

Deactivate the Card flip image slideshow plugin until a patched version is available from the vendor.
Restrict contributor and author account creation, and review existing low-privileged accounts for unauthorized activity.
Implement a strict Content Security Policy (CSP) to limit inline script execution on WordPress administrative pages.

Patch Information

At the time of publication, no fixed version has been identified in the advisory data. The vulnerability affects all versions through 1.5. Consult the Patchstack WordPress Vulnerability Advisory for the latest remediation guidance and patch availability.

Workarounds

Remove the card-flip-image-slideshow plugin from active WordPress installations and replace it with an actively maintained alternative.
Configure a WAF to block requests containing common XSS payloads targeting plugin endpoints.
Enforce least-privilege principles by limiting who can create or edit slideshow content within WordPress.

bash

# Disable and remove the vulnerable plugin via WP-CLI
wp plugin deactivate card-flip-image-slideshow
wp plugin uninstall card-flip-image-slideshow

# Verify the plugin is no longer installed
