CVE-2026-105969 Overview
CVE-2026-105969 is an information disclosure vulnerability in the CodeAtoZ B2B Suite for WooCommerce WordPress plugin before version 1.6.1. The plugin fails to properly restrict access to guest-submitted quotes. Unauthenticated attackers can retrieve another guest's quote by supplying an enumerable identifier. Exposed data includes the buyer's name, email address, and requested line items. The flaw maps to [CWE-200: Exposure of Sensitive Information to an Unauthorized Actor].
Critical Impact
Unauthenticated attackers can enumerate guest quote identifiers to harvest buyer personal data and B2B transaction details from affected WooCommerce storefronts.
Affected Products
- CodeAtoZ B2B Suite for WooCommerce WordPress plugin versions prior to 1.6.1
- WordPress sites running WooCommerce with the vulnerable plugin installed
- Guest quote workflows exposed to unauthenticated network access

Technical Details for CVE-2026-105969
Vulnerability Analysis
The CodeAtoZ B2B Suite for WooCommerce plugin provides a guest quote feature that allows unauthenticated buyers to request pricing on cart items. When a guest submits a quote, the plugin generates a reference identifier used to retrieve the quote later. The plugin does not bind that identifier to a session, cryptographic token, or ownership check. Any unauthenticated client that supplies a valid identifier receives the full quote record in response.
The identifier is enumerable, which means an attacker can iterate through sequential or predictable values to retrieve quotes submitted by other guests. Returned data includes the buyer's name, email address, and the requested line items. The disclosure affects confidentiality only; integrity and availability remain intact.
Root Cause
The root cause is missing authorization on the quote retrieval endpoint, combined with a predictable identifier scheme. The plugin relies on the obscurity of the quote identifier as its sole access control. Because the identifier space is enumerable, obscurity provides no meaningful protection against automated harvesting.
Attack Vector
The attack is remote, unauthenticated, and requires no user interaction. An attacker sends HTTP requests to the quote retrieval endpoint while incrementing or guessing the quote identifier. Each successful response discloses one guest's personal data and B2B order details. See the WPScan Vulnerability Report for additional technical context.
Detection Methods for CVE-2026-105969
Indicators of Compromise
- Repeated HTTP GET requests to the plugin's guest quote retrieval endpoint from a single source IP within a short time window
- Sequential or incrementing values in the quote identifier parameter across consecutive requests
- Unusual outbound data volume from the WordPress site tied to quote endpoints
Detection Strategies
- Review web server access logs for enumeration patterns against guest quote URLs, filtering on request rate per client IP
- Correlate anonymous requests to the plugin endpoints with the absence of a prior quote submission from the same session
- Alert on HTTP responses containing structured customer data returned to unauthenticated clients
Monitoring Recommendations
- Deploy a web application firewall rule to flag high-rate access to quote endpoints with varying identifier parameters
- Monitor WordPress plugin inventory for the CodeAtoZ B2B Suite for WooCommerce and track installed versions against 1.6.1
- Ingest WordPress and web server logs into a centralized analytics platform to baseline normal quote retrieval traffic
How to Mitigate CVE-2026-105969
Immediate Actions Required
- Upgrade the CodeAtoZ B2B Suite for WooCommerce plugin to version 1.6.1 or later on all affected WordPress installations
- Audit web server logs for prior enumeration of the quote endpoint and identify any guest records that may have been exfiltrated
- Notify affected buyers if logs indicate their quote data was accessed by unauthorized parties, consistent with applicable breach disclosure obligations
Patch Information
The vendor addressed the issue in version 1.6.1 of the CodeAtoZ B2B Suite for WooCommerce plugin. Site administrators should update through the WordPress plugin dashboard or by replacing the plugin files with the patched release. Refer to the WPScan Vulnerability Report for advisory details.
Workarounds
- Disable the guest quote feature in the plugin configuration until the update is applied, if business workflows allow
- Restrict access to the plugin's quote endpoints with web application firewall rules that enforce rate limits and block sequential identifier scans
- Temporarily remove the plugin from production sites that cannot be patched immediately and route quote requests through an alternative channel
