CVE-2025-27280: Alobaidi Archive Page XSS Vulnerability

CVE-2025-27280 Overview

CVE-2025-27280 is a DOM-based Cross-Site Scripting (XSS) vulnerability in the Alobaidi Archive Page WordPress plugin. The flaw affects all versions of the archive-page plugin up to and including version 1.0.2. It is classified under CWE-79, Improper Neutralization of Input During Web Page Generation.

An authenticated attacker with low privileges can inject malicious script that executes in the browser of a user who interacts with a crafted request. Successful exploitation requires user interaction and can result in session compromise, content manipulation, and limited data exposure across a scope change boundary.

Critical Impact
Attackers can execute arbitrary JavaScript in the context of a victim's browser session on affected WordPress sites, enabling cookie theft, session hijacking, and unauthorized actions on behalf of the victim.

Affected Products

Alobaidi Archive Page WordPress plugin (archive-page)
All versions from initial release through 1.0.2
WordPress installations using the vulnerable plugin

Technical Details for CVE-2025-27280

Vulnerability Analysis

The vulnerability is a DOM-based XSS flaw in the Archive Page plugin for WordPress. DOM-based XSS occurs when client-side JavaScript writes attacker-controlled data into the Document Object Model without proper sanitization or encoding. The malicious payload never needs to reach the server in a reflected form; it executes entirely in the victim's browser.

Exploitation requires an authenticated user with at least low-level privileges to trigger the injection point. A separate user must interact with the crafted content for the payload to execute. Because the vulnerability changes security scope, injected script can affect resources beyond those controlled by the vulnerable component.

Root Cause

The root cause is improper neutralization of input during web page generation within the plugin's client-side code paths. The plugin fails to sanitize or encode attacker-controlled values before inserting them into the DOM. This allows arbitrary HTML and JavaScript to be parsed and executed by the browser.

Attack Vector

The attack is delivered over the network and requires user interaction. An attacker with low-privilege access to the WordPress instance submits crafted input containing a JavaScript payload. When a target user loads or interacts with the affected page, the browser processes the payload and executes it in the victim's session context. See the Patchstack advisory for additional technical details.

Detection Methods for CVE-2025-27280

Indicators of Compromise

Unexpected <script> tags, javascript: URIs, or event handler attributes (onerror, onload) stored in Archive Page plugin content or configuration fields
Outbound requests from user browsers to unfamiliar domains shortly after visiting pages rendered by the archive-page plugin
WordPress access logs showing authenticated POST requests from low-privileged accounts modifying plugin-controlled fields

Detection Strategies

Review WordPress database entries associated with the Archive Page plugin for HTML or JavaScript payloads that should not appear in plain content
Deploy a web application firewall (WAF) rule to flag requests containing common XSS payload patterns targeting the plugin's endpoints
Enable Content Security Policy (CSP) reporting to identify script executions from unexpected sources or inline contexts

Monitoring Recommendations

Monitor authentication logs for anomalous session activity that could indicate cookie or token theft
Track modifications to WordPress plugin content by low-privileged accounts and alert on suspicious HTML characters
Audit browser telemetry from administrator sessions for unexpected script execution on plugin-rendered pages

How to Mitigate CVE-2025-27280

Immediate Actions Required

Deactivate the Alobaidi Archive Page plugin (archive-page) until a patched version is available
Restrict content-editing privileges to trusted user accounts and audit existing low-privileged users
Rotate WordPress administrator and editor session cookies to invalidate any stolen tokens

Patch Information

At the time of publication, no vendor patch is referenced in the NVD entry for versions beyond 1.0.2. Site owners should monitor the Patchstack vulnerability database and the WordPress plugin repository for a fixed release. If no patch is released, permanent removal of the plugin is recommended.

Workarounds

Remove the archive-page plugin entirely if a patched version is not available
Implement a strict Content Security Policy that disallows inline scripts and unauthorized script sources
Configure a WAF ruleset to block XSS payload patterns targeting the plugin's request endpoints
Apply the principle of least privilege to WordPress user roles that can submit content processed by the plugin

bash

# Disable the vulnerable plugin using WP-CLI
wp plugin deactivate archive-page
wp plugin delete archive-page

# Verify removal
wp plugin list --status=active | grep archive-page
