Deeper analysis

CVE-2026-27541 is an Incorrect Privilege Assignment vulnerability (CWE-266) in the Wholesale Suite WordPress plugin (woocommerce-wholesale-prices) developed by Josh Kohlbach. The flaw enables privilege escalation and affects the plugin from unknown initial versions through 2.2.6. Published on 2026-03-05, it carries a CVSS v3.1 base score of 7.1 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L).

A low-privileged user (PR:L) can exploit this vulnerability over the network (AV:N) with high attack complexity (AC:H) and without requiring user interaction (UI:N). Successful exploitation grants high confidentiality and integrity impacts (C:H/I:H) alongside low availability impact (A:L), allowing the attacker to escalate privileges within the affected WordPress environment.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly counters the CWE-266 incorrect privilege assignment by ensuring the Wholesale Suite plugin cannot grant a low-privileged user escalated rights beyond what is explicitly required.

prevent

Enforces access-control decisions so that the plugin's flawed privilege logic cannot be abused to obtain unauthorized C:H/I:H capabilities.

prevent

Requires explicit account and privilege provisioning processes that would limit the initial low-privilege account's ability to reach the vulnerable plugin code path.
