CVE-2026-1852 Overview
The Product Pricing Table by WooBeWoo plugin for WordPress contains a Cross-Site Request Forgery (CSRF) vulnerability in all versions up to and including 1.1.0. This security flaw exists due to missing or incorrect nonce validation on the updateLabel() and remove() functions. Successful exploitation allows unauthenticated attackers to inject arbitrary web scripts into pages or delete pricing tables by crafting malicious requests that trick site administrators into clicking on a specially crafted link.
Critical Impact
Unauthenticated attackers can manipulate WordPress site content by injecting malicious scripts or deleting pricing tables through CSRF attacks targeting administrative users.
Affected Products
- Product Pricing Table by WooBeWoo plugin for WordPress version 1.1.0 and earlier
- WordPress installations with the vulnerable plugin versions installed and active

Technical Details for CVE-2026-1852
Vulnerability Analysis
This vulnerability is classified as CWE-352 (Cross-Site Request Forgery). The flaw resides in the lack of proper nonce validation within the plugin's administrative functions, specifically affecting the updateLabel() and remove() operations. When a WordPress plugin fails to implement adequate nonce checks, it becomes susceptible to CSRF attacks where malicious actors can forge requests that appear legitimate to the server.
The attack requires user interaction, as the attacker must trick an authenticated administrator into clicking a malicious link or visiting a crafted page while logged into the WordPress dashboard. Once the administrator performs this action, the forged request executes with their privileges, enabling unauthorized modifications to pricing table content or complete deletion of tables.
Root Cause
The root cause of this vulnerability is improper implementation of WordPress security best practices. Specifically, the updateLabel() and remove() functions in the Product Pricing Table plugin do not properly verify WordPress nonces before processing requests. Nonces (number used once) are essential security tokens that WordPress uses to validate that requests originate from legitimate user actions rather than forged external sources.
Without proper nonce validation, the plugin cannot distinguish between genuine administrative actions and malicious requests initiated from attacker-controlled contexts.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker would craft a malicious HTML page or email containing hidden forms or scripts that automatically submit requests to the vulnerable plugin endpoints. When an authenticated WordPress administrator views this malicious content while logged in, their browser automatically includes session cookies with the forged request, causing the WordPress server to process it as a legitimate administrative action.
The attack can result in two primary outcomes: injection of arbitrary JavaScript code into pricing table labels (leading to stored XSS) or unauthorized deletion of pricing tables (leading to data loss and site functionality disruption).
Detection Methods for CVE-2026-1852
Indicators of Compromise
- Unexpected modifications to pricing table labels or content, particularly containing JavaScript or HTML elements
- Missing pricing tables that were not intentionally deleted by administrators
- Unusual administrative activity in WordPress access logs targeting the WooBeWoo plugin endpoints
- User reports of unexpected behavior or pop-ups when viewing pages with pricing tables
Detection Strategies
- Monitor WordPress audit logs for unusual updateLabel or remove operations on pricing tables
- Implement web application firewall (WAF) rules to detect CSRF attack patterns targeting WordPress admin endpoints
- Review server logs for suspicious referrer headers indicating requests originating from external domains
- Deploy file integrity monitoring to detect unexpected changes to pricing table database records
Monitoring Recommendations
- Enable comprehensive logging for WordPress administrative actions using security plugins
- Configure alerts for bulk modifications or deletions of pricing table content
- Implement Content Security Policy (CSP) headers to help mitigate injected script execution
- Regularly audit pricing table content for signs of unauthorized script injection
How to Mitigate CVE-2026-1852
Immediate Actions Required
- Update the Product Pricing Table by WooBeWoo plugin to version 1.1.1 or later immediately
- Review pricing table content for any signs of unauthorized modifications or script injections
- Audit administrative user activity logs for suspicious actions during the exposure window
- Educate administrators about CSRF attack vectors and the importance of not clicking suspicious links while logged in
Patch Information
The vulnerability has been addressed in version 1.1.1 of the Product Pricing Table by WooBeWoo plugin. The patch implements proper nonce validation on the affected updateLabel() and remove() functions. For more details, refer to the GitHub Release v1.1.1 and the Wordfence Vulnerability Report.
Workarounds
- If immediate patching is not possible, consider temporarily deactivating the Product Pricing Table plugin until the update can be applied
- Implement additional CSRF protection at the web application firewall level
- Restrict administrative access to trusted IP addresses to reduce the attack surface
- Train WordPress administrators to log out of the dashboard when not actively managing the site
