SlowMist:PHP discloses critical remote code execution vulnerabilities,CVSS v4.0 both rated 9.2 According to BlockBeats,October 21, SlowMist stated in a post that PHP released a security advisory on October 20, disclosing critical vulnerabilities that could lead to remote code execution (RCE), identified as CVE-2026-109618 and CVE-2026-109619，CVSS v4.0, both rated 9.2. Official patches have not yet been released, and the technical details, exploitation conditions, and affected versions have yet to be officially confirmed.
Third-party reports state that PHP 5 and later versions may be affected, but this scope has not been verified. The official security update is expected to be released on October 21 at 14: 00 UTC(Beijing time 22: 00).
SlowMist recommends that relevant teams check the version of PHP in their servers and business systems, prioritize internet-facing services, and update as soon as possible after official patches are released. If remediation is temporarily not possible, access to exposed PHP services should be restricted and isolated if necessary.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
Remote code execution means that an attacker may be able to run code on the target server.CVSS 9.2 indicates that the severity ratings in the report are high, but the affected PHP versions, how the vulnerabilities are triggered, and the patch status have not yet been fully confirmed.
Why it matters to readers
If internet-facing PHP services are affected and not remediated promptly, they may face the risk of remote exploitation. Exposed services should therefore be prioritized for inspection, and official security updates should be monitored.
Beginners using PHP to build websites or maintain servers should first confirm their own PHP version and whether their services are exposed to the internet, and monitor official updates; do not treat the unverified scope of “PHP 5 and later versions” as definitive.
Risks and unknowns
The technical details of the vulnerabilities have not yet been officially confirmed.
The exploitation conditions of the vulnerabilities have not yet been officially confirmed.
The affected PHP versions have not yet been officially confirmed.
PHP 5 and later versions may be affected originates from third-party reports and has not been verified.
Official patches had not yet been released at the time of publication; an expected release time does not mean they have already been released.
The evidence does not indicate whether the vulnerabilities have been exploited in the wild.
