CVE-2026-107429 Overview
CVE-2026-107429 is an input validation vulnerability in the VideoWhisper.com Paid Videochat Turnkey Site (ppv-live-webcams) WordPress plugin. The flaw affects all versions up to and including 7.5.12. An authenticated attacker with low privileges can manipulate input data submitted to the plugin because the application fails to properly validate the specified quantity of input values. The weakness is tracked under CWE-1284, Improper Validation of Specified Quantity in Input. Exploitation requires network access and no user interaction, but it affects integrity only; confidentiality and availability are not impacted.
Critical Impact
Authenticated low-privilege users can manipulate input values processed by the Paid Videochat Turnkey Site plugin, altering data handled by the application.
Affected Products
- VideoWhisper.com Paid Videochat Turnkey Site (ppv-live-webcams) WordPress plugin
- All versions from n/a through 7.5.12
- WordPress sites running the vulnerable plugin version

Technical Details for CVE-2026-107429
Vulnerability Analysis
The vulnerability resides in the ppv-live-webcams plugin, which powers paid videochat features for WordPress sites. The plugin accepts input from authenticated users but does not enforce proper validation on the quantity of values supplied. Attackers can submit crafted input containing an unexpected number of elements, which the application processes without rejecting or sanitizing.
The weakness falls under CWE-1284. This class of flaw occurs when software fails to check whether input matches expected cardinality constraints such as array length, parameter count, or value range. The result is manipulation of application state or data handled downstream.
Root Cause
The plugin trusts client-supplied input without validating structural expectations. According to the Patchstack advisory, the plugin categorizes this as Input Data Manipulation. The missing validation permits an authenticated user to alter data that should otherwise be constrained to specific values or counts.
Attack Vector
Exploitation requires network access to the WordPress site and valid low-privileged credentials. No user interaction is needed. An attacker crafts an HTTP request to a plugin endpoint with manipulated input values that bypass the expected quantity constraints. The server processes the malformed request and acts on the manipulated data, affecting integrity of plugin-managed records.
No verified public exploit code is available for this issue at the time of publication. Technical details are described in prose only; see the Patchstack advisory for additional context.
Detection Methods for CVE-2026-107429
Indicators of Compromise
- Unexpected modifications to records managed by the ppv-live-webcams plugin, such as session, billing, or user-profile entries.
- HTTP POST requests to plugin endpoints containing abnormal parameter counts or array structures from authenticated low-privilege accounts.
- Audit log entries showing data changes that do not correlate with legitimate user actions in the videochat workflow.
Detection Strategies
- Review WordPress access logs for requests to /wp-admin/admin-ajax.php and plugin routes containing parameters tied to ppv-live-webcams.
- Compare plugin database tables against expected schemas and value ranges to identify entries altered outside normal workflows.
- Correlate authenticated session activity with record changes to flag low-privilege accounts performing unexpected write operations.
Monitoring Recommendations
- Enable verbose logging for the plugin and forward WordPress audit logs to a centralized log platform for retention and search.
- Alert on anomalous POST payload sizes or parameter counts targeting plugin endpoints.
- Track account creation and privilege changes on sites running the plugin to identify low-privilege accounts used for exploitation.
How to Mitigate CVE-2026-107429
Immediate Actions Required
- Identify all WordPress sites running the ppv-live-webcams plugin and inventory installed versions.
- Restrict registration or disable low-privilege account creation on affected sites until a patched version is deployed.
- Review recent plugin activity for signs of data manipulation and roll back unauthorized changes.
Patch Information
At the time of publication, the Patchstack advisory lists the vulnerability as affecting versions up to and including 7.5.12. Administrators should monitor the Patchstack entry and the plugin vendor's release page for a fixed version and apply it as soon as it becomes available.
Workarounds
- Place the WordPress site behind a web application firewall and add rules that validate parameter counts and array lengths submitted to plugin endpoints.
- Temporarily deactivate the ppv-live-webcams plugin on sites that do not require active videochat features.
- Enforce the principle of least privilege and audit existing low-privilege accounts to remove unused or suspicious users.
# Example: list installed version of the affected plugin using WP-CLI
wp plugin get ppv-live-webcams --field=version
# Deactivate the plugin as a temporary mitigation
wp plugin deactivate ppv-live-webcams
