A newly disclosed PHP vulnerability affecting roughly 70% of web sites has raised urgent security concerns for authors who run WordPress‑based sites.

A security flaw in the PHP programming language, revealed last week, is reported to impact about 70% of all web sites, according to the Alliance of Independent Authors.

The vulnerability, described as critical, could allow attackers to exploit unpatched WordPress installations that many self‑published authors rely on for their online presence.

While the source does not provide technical details, it urges site owners to verify that their hosting environments and WordPress core, themes, and plugins are updated to the latest versions.

Authors are advised to consult their web‑hosting providers or IT contacts to ensure patches are applied promptly, reducing the risk of compromise.

Maintaining up‑to‑date software is presented as the primary defence against the newly disclosed threat.
