Deferred Deferred - Pending Action

Stored XSS in WP Photo Album Plus WordPress Plugin

Publication date: 2026-10-10

Last updated on: 2026-10-13

Assigner: Wordfence

Description

The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REQUEST_URI Session History in all versions up to, and including, 9.3.03.002 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The bypass works because esc_url_raw() strips literal angle brackets but retains HTML entities, which wppaEntityDecode() silently converts back to live HTML tags before jQuery('#wppa-modal-container').html() renders them.

Attack-Flow Graph

Executive Summary

The WP Photo Album Plus plugin for WordPress has a stored cross-site scripting (XSS) vulnerability due to insufficient input sanitization and output escaping. Attackers can inject malicious scripts into pages via the REQUEST_URI parameter. These scripts execute when users access the infected pages. The issue involves HTML entities being converted back to live HTML tags before rendering.

Detection Guidance

Check for the presence of the WP Photo Album Plus plugin in your WordPress installation. Review server logs for suspicious script injections in REQUEST_URI parameters. Inspect pages where the plugin is active for unexpected HTML or JavaScript content in session history.

Impact Analysis

Unauthenticated attackers can inject arbitrary web scripts into pages. When users visit these pages, the injected scripts execute, potentially stealing user data, session cookies, or performing actions on their behalf. This could lead to account compromise or unauthorized access to sensitive information.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality principles. For HIPAA, it may expose protected health information, risking compliance with safeguard requirements. Both standards mandate protecting against unauthorized data exposure.

Mitigation Strategies

Update the WP Photo Album Plus plugin to the latest version beyond 9.3.03.002. If an update is unavailable, consider disabling the plugin temporarily. Review and sanitize all user inputs related to the plugin's functionality.
