CVE-2026-8419 submone CVE debrief
Cross-Site Request Forgery (CSRF) vulnerability in the Amazon Scraper WordPress plugin allows unauthenticated attackers to modify plugin settings and inject malicious web scripts via forged requests, contingent on social engineering an administrator into clicking a malicious link. The vulnerability stems from missing or incorrect nonce validation on an administrative function. Affected versions include all releases up to and including 1.1. The CVSS 3.1 score of 4.3 (Medium) reflects network attack vector, low attack complexity, no required privileges, but requires user interaction. The vulnerability was disclosed on 2026-05-20 with source analysis pointing to specific lines in amazon-admin.php across both tagged release 1.1 and trunk development versions. No known exploitation in the wild or ransomware campaign association has been reported.

Who should care
WordPress site administrators using the Amazon Scraper plugin; security teams managing WordPress installations; web application security assessors evaluating plugin security postures
Technical summary
The Amazon Scraper plugin for WordPress fails to implement proper nonce validation on an administrative function, enabling CSRF attacks. An unauthenticated attacker can craft a malicious request that, when executed by an authenticated administrator through social engineering (e.g., clicking a link), modifies plugin settings and injects arbitrary web scripts. The vulnerability affects all versions through 1.1. Source analysis indicates the vulnerable code paths reside in amazon-admin.php at multiple line locations in both the stable release and development trunk.
Defensive priority
medium
Recommended defensive actions
- Verify if Amazon Scraper plugin is installed and identify version through WordPress admin panel or filesystem inspection
- Upgrade to version 1.2 or later if available, or remove the plugin if no patch is released
- Implement additional CSRF protection at the web application firewall level for WordPress administrative endpoints
- Review WordPress admin user activity logs for unauthorized settings changes in amazon-admin.php context
- Apply principle of least privilege to WordPress administrative accounts
- Consider implementing Content Security Policy headers to mitigate impact of any successful script injection
Evidence notes
