Kaseya is aware of two critical vulnerabilities in PHP: CVE-2026-109618 and CVE-2026-109619. CVE-2026-109618 involves a remote code execution vulnerability where handling out-of-memory errors via longjmp() leaves request memory uninitialized due to improper control flow management, potentially allowing attackers to achieve remote code execution using out-of-memory (OOM) triggers. CVE-2026-109619 describes a remote code execution vulnerability where longjmp() fatal error handling leaves global memory pointing to freed memory regions. These regions can later be accessed during subsequent requests, potentially enabling arbitrary code execution. Kaseya has completed an evaluation of its product portfolio regarding these vulnerabilities. A summary of the current status across impacted products and services is provided in the table below.
