This security bulletin contains information about 2 vulnerabilities.

1) PHP file inclusion (CVE-ID: N/A)

CWE-ID: CWE-98 - Improper Control of Filename for Include/Require Statement in PHP Program

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote user to execute arbitrary code.

The vulnerability exists due to improper control of filename for include/require statement in PHP program in the controller dispatcher and backup import functionality when handling a crafted backup archive and a user-controlled module path. A remote privileged user can upload a crafted gzip-compressed tar archive and invoke the dispatcher with a phar:// module path to execute arbitrary code.

The issue relies on the backup-management permission and on the ability to reference the uploaded archive through PHP's phar:// stream wrapper.
