CVE-2024-30515: 
WordPress vulnerability analysis and mitigation

The Events Manager WordPress plugin contains a Missing Authorization vulnerability (CVE-2024-30515) affecting versions up to and including 6.4.6.4. The vulnerability was discovered and reported by Abdi Pranata, and a fix was released in version 6.4.7. This security issue allows authenticated attackers with subscriber-level access and above to perform unauthorized actions (Patchstack, WPScan).

The vulnerability is classified as CWE-862 (Missing Authorization) and has received varying CVSS v3.1 severity scores. The National Vulnerability Database (NVD) assigned a High severity score of 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), while Patchstack rated it as Medium severity with a score of 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N). The vulnerability stems from a missing capability check in the plugin's functionality (NVD).

The vulnerability enables authenticated users with subscriber-level permissions or higher to perform unauthorized actions within the Events Manager plugin. This broken access control issue could potentially lead to unauthorized access to plugin features and functionalities that should be restricted to users with higher privilege levels (WPScan).

The vulnerability requires an attacker to have at least subscriber-level authentication to exploit. While the exact details of exploitation are not publicly disclosed, the low complexity rating (AC:L) in the CVSS scores indicates that the vulnerability is relatively straightforward to exploit once the attacker has the required access level (NVD).

Website administrators are strongly advised to update the Events Manager plugin to version 6.4.7 or later, which contains the fix for this vulnerability. For users unable to update immediately, Patchstack has issued a virtual patch to mitigate this issue by blocking potential attacks until the update can be applied (Patchstack).
