CVE-2026-24944 identifies a Missing Authorization vulnerability in the weDevs Subscribe2 plugin, a WordPress subscription management tool. The vulnerability arises from incorrectly configured access control security levels, allowing unauthenticated remote attackers to bypass authorization checks. This can lead to unauthorized access to sensitive subscription data, resulting in a high confidentiality impact. The integrity impact is limited, as attackers cannot modify data, and availability is unaffected. The CVSS 3.1 base score is 6.5, with vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N, indicating network attack vector, high attack complexity, no privileges or user interaction required, unchanged scope, high confidentiality impact, low integrity impact, and no availability impact. The vulnerability affects Subscribe2 versions up to 10.44, though exact affected versions are not specified. No public exploits are known at this time. The issue was reserved in January 2026 and published in February 2026. The root cause is a failure to enforce proper authorization checks on certain plugin functionalities, exposing subscription data to unauthorized parties. This vulnerability is critical for organizations using Subscribe2 for managing subscriber lists and communications, as it risks data confidentiality breaches.

The primary impact of CVE-2026-24944 is unauthorized disclosure of sensitive subscription data managed by the Subscribe2 plugin. This can lead to privacy violations, exposure of subscriber information, and potential reputational damage for affected organizations. Since the vulnerability does not allow data modification or service disruption, the integrity and availability impacts are limited. However, the confidentiality breach alone can have significant consequences, especially for organizations handling personal or sensitive subscriber information. Attackers exploiting this flaw could harvest subscriber emails and related data, potentially facilitating phishing campaigns or further attacks. The medium severity reflects the balance between the high confidentiality impact and the high attack complexity, which reduces the likelihood of widespread exploitation. Organizations worldwide using Subscribe2 are at risk, particularly those with large subscriber bases or sensitive data. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the need for proactive mitigation.

1. Monitor the weDevs official channels for security patches addressing CVE-2026-24944 and apply them promptly once available. 2. Conduct a thorough review of Subscribe2 plugin configurations to ensure access control settings are correctly enforced, restricting unauthorized access. 3. Limit plugin permissions to only necessary roles and users within the WordPress environment to reduce exposure. 4. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting Subscribe2 endpoints. 5. Regularly audit logs for unusual access patterns or unauthorized attempts to access subscription data. 6. Consider temporarily disabling the Subscribe2 plugin if immediate patching is not possible and the risk is deemed high. 7. Educate administrators on the importance of plugin updates and secure configuration management. 8. Employ network segmentation and least privilege principles to isolate critical web services and data. These steps go beyond generic advice by focusing on configuration review, monitoring, and layered defenses tailored to the Subscribe2 plugin context.
