Hello, I have developed a backported .patch for EOL versions of PHP
(specifically PHP 5.4, 5.5, and 5.6) to mitigate the critical PHP2Shell
Out-of-Memory (OOM) vulnerability (CVE-2026-109618 / CVE-2026-109619). Since
these legacy versions are no longer supported by the upstream PHP team, this
patch updates the internal memory allocation model to prevent memory exhaustion
and crashes during file upload progress tracking. The patch and instructions
are publicly available on GitHub:
