CVE-2024-10729 is a vulnerability classified under CWE-285 (Improper Authorization) found in the Booking & Appointment Plugin for WooCommerce, developed by Tyche Softwares. This plugin is widely used on WordPress sites to manage bookings and appointments. The vulnerability exists because the 'save_google_calendar_data' function lacks proper capability checks, allowing any authenticated user with subscriber-level permissions or higher to invoke this function and update site options arbitrarily. Site options in WordPress control critical configuration settings, and unauthorized modification can lead to severe consequences including site defacement, data leakage, privilege escalation, or complete site takeover. The vulnerability affects all versions up to and including 6.9.0. The CVSS v3.1 score is 8.8 (high), reflecting network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are currently known, the vulnerability is straightforward to exploit by any authenticated user, including subscribers, which are common roles on WordPress sites. This makes the threat particularly dangerous for sites that allow user registration or have multiple users with low privileges. The vulnerability was published on November 26, 2024, and no official patches are linked yet, indicating the need for close monitoring of vendor updates. The flaw could be leveraged to manipulate site settings, inject malicious configurations, or disrupt normal site operations, severely impacting business continuity and trust.

The impact of CVE-2024-10729 is significant for organizations using the affected plugin on WordPress sites. Unauthorized modification of site options can lead to complete compromise of the website, including data breaches, defacement, or persistent backdoors. Attackers with subscriber-level access can escalate privileges or alter critical configurations, potentially disrupting booking and appointment services, which are often business-critical. This can result in loss of customer trust, financial losses, and reputational damage. The vulnerability's ease of exploitation and high impact on confidentiality, integrity, and availability make it a critical risk for e-commerce, service providers, and any organization relying on WooCommerce for customer interactions. Additionally, the lack of user interaction requirement means automated attacks or mass exploitation campaigns could emerge quickly once exploit code becomes available. Organizations with multi-user environments or open registration are particularly vulnerable, increasing the attack surface and likelihood of exploitation.

To mitigate CVE-2024-10729, organizations should: 1) Monitor Tyche Softwares' official channels for patches and apply updates immediately once available. 2) Temporarily restrict user roles and permissions, especially limiting subscriber-level users from accessing or triggering booking plugin functions. 3) Implement strict role-based access controls (RBAC) and audit user capabilities regularly to ensure minimal privileges. 4) Use Web Application Firewalls (WAFs) to detect and block suspicious requests targeting the vulnerable function. 5) Monitor WordPress site options and configuration changes for unauthorized modifications using file integrity monitoring and logging tools. 6) Consider disabling or replacing the affected plugin if immediate patching is not possible. 7) Educate site administrators about the risks of granting unnecessary permissions to low-privilege users. 8) Conduct regular security assessments and penetration tests focusing on plugin vulnerabilities and authorization controls. These steps go beyond generic advice by focusing on access control hardening, monitoring, and proactive risk reduction tailored to this specific vulnerability.
