CVE-2026-34903 affects the Ocean Extra plugin for WordPress, a popular tool for enhancing website functionality. This vulnerability stems from a missing capability check, enabling authenticated users with Subscriber access or higher to execute actions they shouldn't be able to. Versions of the plugin up to and including 2.5.3 are impacted, but a patch has been released in version 2.5.4 to address this issue.
CVE-2026-34903 in the Ocean Extra WordPress plugin introduces an unauthorized access vulnerability. A missing capability check on a function within the plugin allows authenticated attackers, with Subscriber-level access or higher, to perform unauthorized actions. The potential impact ranges depending on the functionality exposed by the vulnerable function, potentially leading to data modification, unauthorized code execution, or access to sensitive information. This vulnerability is considered significant as it affects a wide range of websites utilizing Ocean Extra and enables attackers with limited privileges to escalate their access.
An attacker with Subscriber or higher access on a website using Ocean Extra versions up to 2.5.3 can exploit this vulnerability. The attacker needs to identify the vulnerable function and the method to invoke it without the proper capability check. This could involve manipulating URL parameters, sending malicious POST requests, or exploiting other vulnerabilities on the website to gain access to the function. The success of exploitation depends on the attacker's knowledge of the plugin's internal structure and how its functions are accessed.
