Two Critical PHP Flaws Raise Security Concerns for Crypto Platforms

Two critical PHP vulnerabilities could pose remote-code-execution risks for crypto platforms that use the software. The flaws, CVE-2026-109618 and CVE-2026-109619, each carry a 9.2 severity score. Organizations that rely on PHP should review their installations for exposure. PHP is used in backend development, putting crypto platforms that depend on it within the scope of the alert. SlowMist flagged the vulnerabilities as a concern for crypto platforms. The flaws are in PHP itself, so the relevant exposure is a platform’s web infrastructure, rather than a blockchain or crypto asset. Official patches were pending as of Oct. 21.
