CVE-2025-49988: 
WordPress vulnerability analysis and mitigation

CVE-2025-49988 is a Missing Authorization vulnerability in the Contact Form 7 AWeber Extension WordPress plugin (slug: integrate-contact-form-7-and-aweber), developed by Renzo Johnson. The flaw allows unauthenticated attackers to exploit incorrectly configured access control security levels, affecting all versions from n/a through 0.1.40. It was published on June 20, 2025, and carries a CVSS v3.1 base score of 5.3 (Medium) (Feedly, Wordfence).

The vulnerability is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the necessary permissions before executing sensitive operations. Because no authentication or capability checks are enforced on the affected functionality, any unauthenticated network-based attacker can trigger restricted actions. The attack vector is network-accessible, requires no user interaction, and has low attack complexity, making it straightforward to exploit (Feedly).

Successful exploitation results in a limited availability impact (CVSS availability impact: Low), with no direct confidentiality or integrity compromise indicated by the base score. An attacker could abuse the missing authorization checks to trigger unintended plugin operations, potentially disrupting form-to-AWeber integrations or causing denial of service for the affected functionality. The scope is unchanged, limiting blast radius to the vulnerable plugin's own operations rather than broader WordPress site compromise (Feedly).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for CVE-2025-49988 as of the available data. The EPSS score is approximately 0.052%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and no threat actor attribution has been identified (Feedly).

Users should update the Contact Form 7 AWeber Extension plugin to a version beyond 0.1.40 once a patched release is made available by the vendor. In the interim, site administrators should consider deactivating the plugin if it is not actively needed, or restricting access to the WordPress admin area via IP allowlisting. Monitoring plugin activity logs for unexpected or unauthorized requests to plugin endpoints is also advisable (Feedly, Wordfence).

Wordfence included CVE-2025-49988 in its weekly WordPress vulnerability report for the period of June 16–22, 2025, flagging it as part of a broader set of access control issues in WordPress plugins. No significant independent researcher commentary or major media coverage has been identified beyond standard vulnerability database aggregation (Wordfence).
