CVE-2024-12826 identifies a missing authorization vulnerability (CWE-862) in the GoHero Store Customizer for WooCommerce plugin for WordPress. Specifically, the vulnerability resides in the wooh_action_settings_save_frontend() function, which lacks proper capability checks to verify if the user has permission to modify plugin settings. This flaw allows unauthenticated attackers to send crafted requests to update certain plugin settings without any authentication or user interaction. The vulnerability affects all versions up to and including 3.5 of the plugin. While the impact is limited to unauthorized modification of plugin settings, it does not directly compromise confidentiality or availability of the system. The CVSS 3.1 base score is 4.3 (medium), reflecting the ease of remote exploitation (network vector), low attack complexity, and no user interaction required. The vulnerability does not require privileges but the vector indicates PR:L (low privileges), which may be a data inconsistency; however, the description states unauthenticated attackers can exploit it. No patches or exploit code are currently publicly available, and no active exploitation has been reported. This vulnerability could be leveraged to alter store customization settings, potentially enabling further attacks or disrupting e-commerce operations if combined with other vulnerabilities.

The primary impact of CVE-2024-12826 is unauthorized modification of plugin settings in WooCommerce stores using the GoHero Store Customizer plugin. This can lead to altered store appearance, functionality, or behavior, potentially confusing customers or enabling indirect attacks such as phishing or fraud. Although the vulnerability does not directly expose sensitive data or cause denial of service, unauthorized changes could degrade trust or facilitate subsequent exploitation. For organizations relying on WooCommerce for e-commerce, this vulnerability could undermine the integrity of their online storefronts and customer experience. The risk is amplified in large-scale deployments or stores with high traffic and revenue. Additionally, attackers might combine this vulnerability with other flaws to escalate privileges or compromise the broader WordPress environment. Since no authentication is required, the attack surface is broad, increasing the likelihood of opportunistic exploitation if weaponized. However, the absence of known exploits and the medium severity score suggest the threat is moderate but warrants timely remediation.

To mitigate CVE-2024-12826, organizations should immediately update the GoHero Store Customizer for WooCommerce plugin to a fixed version once released by the vendor. In the absence of an official patch, administrators should consider disabling the plugin temporarily to prevent exploitation. Implementing Web Application Firewall (WAF) rules to block unauthorized POST requests targeting the wooh_action_settings_save_frontend() endpoint can reduce risk. Restricting access to the WordPress admin and plugin endpoints via IP whitelisting or VPN can also limit exposure. Regularly auditing plugin permissions and monitoring logs for unusual configuration changes will help detect exploitation attempts. Additionally, applying the principle of least privilege to WordPress user roles and ensuring that only trusted users have plugin management capabilities can reduce the impact of potential attacks. Organizations should also stay informed through vendor advisories and threat intelligence feeds for updates or exploit disclosures related to this vulnerability.
