Deeper analysis
CVE-2026-24524 is a missing authorization vulnerability (CWE-862) in the Tablesome WordPress plugin developed by Essekia. The flaw allows exploitation of incorrectly configured access control security levels and affects all versions of Tablesome up to and including 1.2.8. It carries a CVSS v3.1 base score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N), indicating medium severity with low complexity and no user interaction required.
An attacker with low-privilege access, such as a subscriber or contributor on a vulnerable WordPress site, can exploit this over the network without authentication escalation. Successful exploitation enables limited integrity impacts, such as unauthorized modifications to plugin resources due to bypassed access controls, without affecting confidentiality or availability.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces approved authorizations for plugin resources, preventing the exact missing-authorization bypass described in CVE-2026-24524.
Limits privileges of low-privileged WordPress roles (subscriber/contributor) so they cannot reach the incorrectly configured access-control paths exploited by the flaw.
Ensures access-control decisions are made by the authorization system rather than relying on the plugin's flawed security-level checks.
