CVE-2024-56270 identifies a missing authorization vulnerability in the WP SecureSubmit plugin, a WordPress plugin designed to facilitate secure payment submissions. The vulnerability exists in versions up to and including 1.5.20, where the plugin fails to enforce proper authorization checks when retrieving embedded sensitive data. This flaw allows an attacker to bypass access controls and extract sensitive information embedded within the plugin's functionality. The vulnerability does not require authentication or user interaction, making it remotely exploitable by unauthenticated attackers. Although no exploits are currently known in the wild, the exposure of sensitive data could include payment details or other confidential information handled by the plugin. The lack of a CVSS score limits precise severity quantification, but the missing authorization nature implies a significant risk to confidentiality. The vulnerability affects WordPress sites that have installed and use the WP SecureSubmit plugin, which is likely deployed in e-commerce or payment processing contexts. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for cautious mitigation. The vulnerability was reserved in December 2024 and published in January 2025, indicating recent discovery and disclosure.

The primary impact of CVE-2024-56270 is the unauthorized disclosure of sensitive embedded data managed by the WP SecureSubmit plugin. Organizations using this plugin risk exposure of confidential information such as payment details, customer data, or other sensitive content embedded within the plugin’s operations. This can lead to data breaches, regulatory non-compliance (e.g., PCI DSS violations), reputational damage, and potential financial losses. Since the vulnerability can be exploited remotely without authentication, attackers can target vulnerable WordPress sites at scale, increasing the risk of widespread data leakage. The integrity and availability of systems are less directly impacted; however, the confidentiality breach alone is significant. The lack of known exploits currently limits immediate widespread impact, but the vulnerability’s nature makes it a high-value target for attackers once exploit code becomes available. Organizations relying on WP SecureSubmit for payment processing or sensitive data handling are at particular risk.

1. Monitor the WP SecureSubmit plugin vendor’s official channels for security patches and apply updates immediately once available. 2. Until a patch is released, restrict access to the plugin’s endpoints by implementing web application firewall (WAF) rules that block unauthorized requests targeting WP SecureSubmit functionalities. 3. Limit administrative and plugin access to trusted IP addresses or VPNs to reduce exposure. 4. Conduct thorough audits of server and application logs to detect any suspicious access attempts to the plugin’s data retrieval functions. 5. Consider temporarily disabling the WP SecureSubmit plugin if feasible, especially on sites handling highly sensitive data, until a secure version is released. 6. Employ security plugins or tools that can detect and block unauthorized API or endpoint access. 7. Educate site administrators about the risk and encourage strong access control policies. 8. Review and enhance overall WordPress security posture, including least privilege principles and regular vulnerability scanning.
