For PHPCMS V9, PHP2Shell remediation requires patching the PHP runtime. The application version helps identify compatibility blockers; it cannot establish exploitability or prove that either CVE is fixed.
PHPCMS V9 - PHP compatibility for the PHP2Shell fix
A trustworthy release-to-PHP mapping is not available here. Do not guess a PHP 8 target from a product name or a modern download page. Identify the exact distribution, patch level and local modifications first.

PHPCMS V9 - Remove blockers to patch PHP2Shell
Treat PHPCMS V9 as an inherited application until its distribution and modifications are proven. The historical official site could not be verified during this review, so no universal PHP range is asserted. Inspect database drivers, mysql_* usage, GBK/UTF-8, custom content models and template tags in an offline copy. Preserve attachments and article URLs when repairing or migrating; an online homepage is not an adequate acceptance test. Before exporting PHPCMS content, map category IDs, model IDs, custom fields and attachment references from the actual database; table prefixes vary. Compare representative detail pages and generated paths against the original. Rebuilding only the article text can lose model-specific data and leave image links pointing at the old server.

Verify both CVE fixes in the PHP actually serving this site. Replace or restart old Web workers, queue workers and replicas. A working homepage or a newer CLI binary is insufficient evidence.
