CVE-2025-64241 identifies a missing authorization vulnerability in the WP Coupons and Deals plugin for WordPress, developed by Imtiaz Rayhan. The vulnerability arises from incorrectly configured access control security levels within the plugin, allowing unauthorized users to perform actions that should be restricted. This could include modifying, adding, or deleting coupons and deals, or accessing sensitive administrative functions without proper permissions. The affected versions include all versions up to and including 3.2.4. The vulnerability does not require authentication, increasing its risk profile, and no user interaction is necessary to exploit it. Although no public exploits have been reported, the flaw represents a significant risk because it undermines the fundamental security principle of authorization, potentially leading to unauthorized data manipulation or exposure. The plugin is commonly used in WordPress environments to manage promotional content, making it a target for attackers seeking to disrupt marketing operations or inject malicious content. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability was reserved in late October 2025 and published in December 2025, indicating recent discovery and disclosure. No patches or fixes are currently linked, so organizations must be vigilant and prepare to apply updates promptly once available.

For European organizations, the impact of CVE-2025-64241 can be significant, especially for businesses relying on WordPress for e-commerce, marketing, or affiliate promotions. Unauthorized access to the WP Coupons and Deals plugin could allow attackers to manipulate promotional content, potentially misleading customers, damaging brand reputation, or causing financial losses through fraudulent coupons. Confidentiality may be compromised if sensitive deal information or user data is exposed. Integrity is at risk due to unauthorized content changes, and availability could be indirectly affected if attackers disrupt plugin functionality or the broader WordPress site. Given the widespread use of WordPress across Europe and the popularity of coupon plugins, many SMEs and larger enterprises could be vulnerable. The absence of authentication requirements for exploitation increases the threat level, as attackers can attempt exploitation remotely without credentials. This vulnerability could also be leveraged as a foothold for further attacks within compromised networks. Organizations in regulated sectors must consider compliance implications if customer data or transactional integrity is affected.

1. Monitor official channels for patches or updates from the plugin developer and apply them immediately upon release. 2. Until a patch is available, restrict access to the WordPress admin dashboard and plugin management areas using IP whitelisting, VPNs, or multi-factor authentication to limit exposure. 3. Review and harden WordPress user roles and permissions to ensure only trusted administrators have access to the WP Coupons and Deals plugin settings. 4. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 5. Conduct regular security audits and vulnerability scans focusing on WordPress plugins to identify and remediate similar authorization issues. 6. Educate site administrators about the risks of installing unverified plugins and encourage minimal plugin use to reduce attack surface. 7. Maintain comprehensive backups of WordPress sites and databases to enable rapid recovery in case of compromise. 8. Monitor logs for unusual activity related to coupon or deal management functions to detect potential exploitation attempts early.
