CVE-2025-69328: 
WordPress vulnerability analysis and mitigation

CVE-2025-69328 is a PHP Object Injection vulnerability (Deserialization of Untrusted Data) in the Booking and Rental Manager for WooCommerce WordPress plugin by magepeopleteam. It affects all versions up to and including 2.5.9, and was patched in version 2.6.0. The vulnerability was reported on November 25, 2025, and published on February 9–20, 2026. It carries a CVSS v3.1 base score of 8.8 (High), requiring only low-privilege authentication to exploit (Patchstack, Feedly).

The root cause is improper deserialization of untrusted user-supplied data (CWE-502), classified under OWASP Top 10 A3: Injection and mapped to CAPEC-586 (Object Injection). An authenticated attacker with Contributor-level privileges can supply a crafted serialized PHP object to the plugin, which is deserialized without adequate validation. If a suitable PHP Object Injection (POP) chain exists within the WordPress environment, this can be leveraged to achieve remote code execution, SQL injection, path traversal, or denial of service (Patchstack, Feedly).

Successful exploitation can result in high impact to confidentiality, integrity, and availability of the affected WordPress/WooCommerce installation. An attacker could achieve remote code execution, gain unauthorized access to sensitive data (including customer and booking information), modify or delete booking and rental records, and disrupt store operations. The scope of impact depends on the availability of a POP chain in the target environment, but in worst-case scenarios full system compromise is possible (Patchstack, Feedly).

No public proof-of-concept exploit has been confirmed, and there is no evidence of active in-the-wild exploitation at this time. The EPSS score is approximately 0.024% (0.000240), indicating a currently low probability of exploitation in the near term. However, Patchstack notes that vulnerabilities of this CVSS severity class are frequently used in mass-exploit campaigns targeting WordPress sites at scale. No threat actor attribution or CISA KEV listing has been identified for this CVE (Patchstack, Feedly).

1. Reconnaissance: Identify WordPress sites running the Booking and Rental Manager for WooCommerce plugin version ≤ 2.5.9 using tools like WPScan, Shodan, or by inspecting plugin metadata in publicly accessible readme files.
2. Obtain low-privilege access: Register or obtain a Contributor-level (or higher) account on the target WordPress site, as the vulnerability requires authentication.
3. Identify the vulnerable input: Locate the plugin functionality that accepts and deserializes user-supplied data (e.g., booking form fields or API endpoints that process serialized PHP objects).
4. Craft a malicious serialized payload: Using a PHP gadget chain tool (e.g., PHPGGC), generate a serialized PHP object payload targeting a POP chain available in the WordPress/WooCommerce environment to achieve the desired effect (e.g., RCE, file write).
5. Submit the payload: Send the crafted serialized object via the vulnerable plugin input (e.g., HTTP POST request to the relevant endpoint), triggering deserialization on the server.
6. Achieve objective: Depending on the POP chain used, gain remote code execution, read/write files, perform SQL injection, or cause denial of service on the target server (Patchstack).

• Network: Unusual POST requests to WordPress endpoints associated with the Booking and Rental Manager plugin containing serialized PHP data (e.g., O: patterns in request bodies); unexpected outbound connections from the web server to external IPs.
• Logs: WordPress/PHP error logs showing deserialization-related warnings or fatal errors; access logs with repeated authenticated requests to plugin-specific endpoints with abnormally large or encoded payloads.
• File System: Newly created or modified PHP files in the WordPress uploads directory or plugin directories; presence of web shells or unexpected scripts.
• Process: Unusual child processes spawned by the web server process (e.g., bash, curl, wget, python) following plugin interaction.
• Database: Unexpected changes to booking/rental records, new admin user accounts, or modified WordPress options (e.g., siteurl, admin_email) in the wp_options table.

The vendor (Magepeople Inc.) released version 2.6.0 of the Booking and Rental Manager for WooCommerce plugin, which patches this vulnerability. Site administrators should update immediately to version 2.6.0 or later via the WordPress plugin dashboard. As interim measures, restrict Contributor-level user registrations and permissions, and consider deploying a Web Application Firewall (WAF) rule to detect and block PHP object injection attempts. Patchstack users benefit from an automatic virtual patch (mitigation rule) that blocks exploitation until the plugin is updated (Patchstack).

Patchstack, which coordinated the disclosure, classified this as a medium-priority vulnerability and issued a virtual patch for its users. The vulnerability was credited to researcher Phat RiO, who reported it on November 25, 2025. Wordfence also included this CVE in its weekly WordPress vulnerability report for the period of February 9–15, 2026, indicating broad coverage within the WordPress security community (Patchstack, Wordfence).
