The PHP Security Flaw Is Causing Panic – But We’re Not Affected

Just before Halloween, a digital threat is sending shockwaves across the internet: the PHP security vulnerability. Countless website operators worldwide are affected. Many are preemptively taking their websites and web applications temporarily offline to contain the risk.

But you can breathe easy: heylogin remains unaffected and secure.

What exactly happened?

Any software written in PHP — one of the most widely used programming languages — is exposed to this security risk. This can include banks, hospitals, universities, your favorite online store, or your blog systems, such as WordPress.

At the core of PHP, not just one but two security vulnerabilities were identified that needed to be patched. On Wednesday, October 21, 2026, numerous website operators around the world took their sites offline as a result.

This is not a cyberattack, but a global vulnerability that is all too inviting for hackers.

The flaws in the code are officially not new. The PHP vulnerability was first discovered in August 2026 and investigated behind closed doors.

The fact that this information is now keeping the entire IT industry on edge was rather unintentional. Word got out before the major software update was released, prompting many operators to play it safe.

The vulnerabilities have been formally identified: under the term “php2shell,” two security flaws are grouped with the identifiers CVE-2026-109618 and CVE-2026-109619.

Why is heylogin not affected?

The reason is as simple as it is reassuring: heylogin does not run on PHP. None of our features are built on this programming language, so you can continue to feel safe and secure. Your data is not affected by this threat.

That said, the PHP Foundation urges: “If you are using PHP, it is imperative that you update now.”
