CVE-2025-49061: Porn Videos Embed Plugin XSS Vulnerability

CVE-2025-49061 Overview

CVE-2025-49061 is a stored Cross-Site Scripting (XSS) vulnerability in the perteus Porn Videos Embed WordPress plugin. The flaw affects all versions up to and including 0.9.1. It results from improper neutralization of user-supplied input during web page generation, categorized under [CWE-79]. Authenticated attackers with low privileges can inject malicious JavaScript that persists in the plugin's stored data. When rendered in a victim's browser, the payload executes in the site context, enabling session theft, content defacement, or redirection to attacker-controlled infrastructure.

Critical Impact
Authenticated attackers can inject persistent JavaScript that executes in the browsers of site administrators and visitors, resulting in scoped compromise across the WordPress instance.

Affected Products

perteus Porn Videos Embed WordPress plugin (porn-videos-embed)
All versions from initial release through 0.9.1
WordPress installations with the vulnerable plugin activated

Technical Details for CVE-2025-49061

Vulnerability Analysis

The vulnerability stems from improper neutralization of input during web page generation within the Porn Videos Embed plugin. User-controlled input is written to storage and later reflected into rendered HTML without proper output encoding or sanitization. This produces a stored XSS condition where injected scripts execute every time an affected page is loaded. Because the payload persists server-side, exploitation does not require crafting per-victim links or targeted social engineering campaigns.

Exploitation requires authenticated access with low privileges and user interaction to trigger the stored payload. The scope is changed, meaning the injected script can affect resources beyond the vulnerable component's security context. Consult the Patchstack XSS Vulnerability Advisory for the underlying technical write-up.

Root Cause

The plugin fails to apply WordPress escaping functions such as esc_html(), esc_attr(), or wp_kses() when rendering user-supplied content back to the page. Input accepted through plugin form fields is stored in the database and later emitted directly into the HTML output stream. The absence of contextual output encoding permits <script> tags and event handler attributes to be interpreted by the browser as executable code.

Attack Vector

An authenticated attacker submits a crafted payload containing JavaScript through a plugin-controlled input field. The payload persists in the WordPress database. When an administrator or site visitor loads a page that renders the stored data, the browser executes the attacker's script. Attackers commonly use this primitive to hijack administrator sessions, create rogue administrator accounts through the WordPress REST API, or inject SEO spam and malicious redirects.

No verified public exploit code is available. See the Patchstack advisory for additional context.

Detection Methods for CVE-2025-49061

Indicators of Compromise

Unexpected <script> tags, onerror, onload, or onmouseover attributes stored in WordPress post metadata or plugin configuration tables
Outbound HTTP requests from browsers of authenticated administrators to unfamiliar third-party domains after loading plugin-rendered pages
Creation of unauthorized WordPress administrator accounts or unexpected changes to wp_users and wp_usermeta records
Injected iframe or JavaScript resources loading from domains unrelated to the WordPress site

Detection Strategies

Review the wp_posts, wp_postmeta, and plugin-specific options tables for HTML tags and JavaScript event handlers in fields where they are not expected
Enable WordPress audit logging to capture edits made by low-privileged accounts to plugin-managed content
Deploy a Web Application Firewall (WAF) rule set that flags stored XSS payloads submitted to /wp-admin/admin-post.php and plugin endpoints

Monitoring Recommendations

Monitor endpoint telemetry for administrator browser sessions loading unexpected external scripts after visiting the WordPress admin panel
Alert on new administrator account creation and role escalation events in WordPress logs
Track HTTP POST requests from low-privileged users to plugin configuration endpoints and correlate with subsequent page renders

How to Mitigate CVE-2025-49061

Immediate Actions Required

Deactivate and remove the Porn Videos Embed plugin until a patched release is confirmed by the vendor
Audit all low-privileged WordPress accounts and revoke access for accounts that are inactive or unrecognized
Rotate credentials and invalidate active sessions for administrator accounts that accessed pages rendered by the plugin
Inspect plugin-managed database tables for injected script content and remove any malicious payloads

Patch Information

No fixed version has been published as of the last NVD update. The vulnerability affects all versions through 0.9.1. Monitor the Patchstack advisory and the WordPress plugin repository for a security release from perteus.

Workarounds

Remove the plugin entirely and replace it with a maintained embed solution that applies proper output escaping
Restrict WordPress contributor and author roles to trusted users only, reducing the pool of accounts able to exploit the vulnerability
Deploy a WAF with rules that block HTML tags and JavaScript event handlers in submissions to plugin endpoints
Configure a strict Content Security Policy (CSP) that disallows inline script execution on pages rendered by the plugin

bash

# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate porn-videos-embed
wp plugin delete porn-videos-embed

# Audit stored content for injected script tags
wp db query "SELECT ID, post_title FROM wp_posts WHERE post_content LIKE '%<script%' OR post_content LIKE '%onerror=%';"
