CVE-2021-38345 Detail

Description

The Brizy Page Builder plugin <= 2.3.11 for WordPress used an incorrect authorization check that allowed any logged-in user accessing any endpoint in the wp-admin directory to modify the content of any existing post or page created with the Brizy editor. An identical issue was found by another researcher in Brizy <= 1.0.125 and fixed in version 1.0.126, but the vulnerability was reintroduced in version 1.0.127.

NIST CVSS score
NIST: NVD
Base Score:  6.5 MEDIUM
Vector:  CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N

Base Score:  7.1 HIGH
Vector:  CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
