CVE-2025-49396 is a Missing Authorization vulnerability (CWE-862) identified in the Themify Builder plugin developed by themifyme, affecting versions up to 7.6.7. This vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring at least some level of authentication) to perform unauthorized actions that should be restricted. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). While it does not impact confidentiality or availability, it does affect the integrity of the system by allowing unauthorized modifications or actions within the Themify Builder environment. The CVSS 3.1 base score is 4.3, categorizing it as a medium severity issue. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's root cause is a failure to properly enforce authorization checks, which could allow an authenticated but low-privileged user to escalate their capabilities or manipulate content or settings within the builder plugin beyond their intended permissions. Given that Themify Builder is a popular WordPress page builder plugin, this vulnerability could be leveraged by attackers who have gained limited access to a WordPress site to further compromise the site's integrity.

For European organizations using WordPress sites with the Themify Builder plugin, this vulnerability poses a moderate risk. Unauthorized modification of site content or settings could lead to defacement, misinformation, or insertion of malicious content, potentially damaging brand reputation and user trust. While it does not directly expose sensitive data or cause denial of service, the integrity compromise could be leveraged as a foothold for further attacks, including privilege escalation or deployment of malware. Organizations in sectors with strict compliance requirements (e.g., finance, healthcare, government) could face regulatory scrutiny if unauthorized changes lead to data manipulation or misinformation. Additionally, compromised websites could be used as part of phishing campaigns targeting European users. The medium severity score reflects the need for timely remediation but indicates that the vulnerability is not trivially exploitable without some level of authenticated access.

European organizations should immediately audit their WordPress installations to identify the presence and version of the Themify Builder plugin. Until an official patch is released, it is advisable to restrict access to the WordPress admin and builder interfaces to trusted users only, implementing strong authentication mechanisms such as multi-factor authentication (MFA). Review user roles and permissions to ensure minimal privilege principles are enforced, removing unnecessary editor or contributor rights. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the builder plugin endpoints. Monitor logs for unusual activity related to Themify Builder usage. Consider temporarily disabling or replacing the plugin if feasible. Once a patch is available, prioritize prompt application of updates. Additionally, conduct regular security assessments and penetration tests focusing on access control mechanisms within WordPress environments.
