What is known
The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation on the 'gspb_save_files' function in versions up to, and including, 7.6.2. This makes it possible for authenticated attackers with administrator-level capabilities or above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
Business impact
Successful exploitation of CVE-2023-6636, a high vulnerability (CVSS 7.2) affecting greenshift, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action

Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation.
