For Joomla, 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.

Joomla - Remove blockers to patch PHP2Shell
Use Joomla’s installed manifest and pre-update check to identify core and extension compatibility. Upgrade templates, overrides and third-party plugins along the documented major-version route. A compatibility plugin can help a transition but does not certify every extension. Back up files and database together, test schema updates, then check administrator login and multilingual routing.
