CVE-2025-64241 identifies a missing authorization vulnerability in the WP Coupons and Deals WordPress plugin developed by Imtiaz Rayhan, affecting all versions up to and including 3.2.4. This vulnerability arises from incorrectly configured access control security levels within the plugin, allowing attackers with low privileges (PR:L) to perform unauthorized actions remotely (AV:N) without requiring user interaction (UI:N). The vulnerability primarily impacts confidentiality (C:L) by potentially exposing sensitive coupon data or enabling unauthorized viewing of coupon management interfaces, but it does not affect integrity or availability. The plugin is commonly used to manage and display coupons and deals on WordPress-based e-commerce or marketing websites. Exploiting this flaw could allow an attacker to access or manipulate coupon data that should be restricted, potentially leading to information disclosure or unauthorized coupon usage. The CVSS score of 4.3 reflects a medium severity level, indicating moderate risk. No known exploits are currently reported in the wild, and no official patches have been linked, suggesting that mitigation currently relies on configuration and monitoring. The vulnerability was reserved in late October 2025 and published in mid-December 2025, indicating recent discovery and disclosure. Given the widespread use of WordPress and the popularity of coupon plugins in online retail, this vulnerability poses a tangible risk to affected sites if left unaddressed.

For European organizations, this vulnerability could lead to unauthorized disclosure of coupon or deal information, which may undermine marketing campaigns, cause financial losses due to unauthorized coupon redemption, or damage customer trust. While the impact on core business operations is limited since integrity and availability are unaffected, the confidentiality breach could expose sensitive promotional strategies or customer data linked to coupon usage. E-commerce platforms and marketing agencies relying on WP Coupons and Deals are particularly at risk. The medium severity suggests that while the threat is not critical, it should not be ignored, especially for organizations with high volumes of online transactions or sensitive promotional data. Exploitation could also serve as a foothold for further attacks if combined with other vulnerabilities. European organizations must consider the risk in the context of GDPR, as unauthorized access to customer-related data could have compliance implications.

1. Monitor official channels for patches or updates from the plugin developer and apply them immediately upon release. 2. In the interim, restrict access to coupon management interfaces to trusted administrators only, using WordPress role management and additional web application firewalls (WAF) rules. 3. Conduct an audit of user privileges to ensure no unnecessary low-privilege accounts have access to sensitive coupon functions. 4. Implement network-level access controls to limit exposure of the WordPress admin panel, such as IP whitelisting or VPN access. 5. Enable detailed logging and monitoring of coupon-related API calls or admin actions to detect suspicious activity. 6. Consider temporarily disabling the plugin if the risk outweighs the business need until a patch is available. 7. Educate administrators on the risks of unauthorized coupon access and encourage prompt reporting of anomalies. 8. Review and harden WordPress security configurations overall, including keeping the core and all plugins up to date.
