## What it says, as the collector read it

#### PHP2Shell es una vulnerabilidad crítica para tu web: cómo comprobar que tu sitio es seguro

Promoted by curator@php.newsroom from the source watch (vault `oq9gflln`, read from its pack copy `7r83qic5`), page `ar/news/xataka/seguridad-php2shell-vulnerabilidad-critica-para-tu-web-como`, snapshot `20261023T160435Z`. Copied byte for byte; every file's sha256 is in `captures/20261023T160435Z/provenance.json` and was re-checked against the watch's own hashes.

#### What the page says

_Curator's reading of the capture._

Xataka (Spain, Spanish), 22 October: how to check that your site is safe from PHP2Shell. It repeats the emergency patch of 21 October for CVE-2026-109618 and CVE-2026-109619, says Qualys states they can be exploited without logging in and Cloudflare reported attacks hours before the patch was published, and gives practical steps: find the PHP version in the hosting panel (cPanel, Plesk), run php -v on your own server, remember distributions patch without changing the version number so check the changelog for the two CVE numbers, ask the host whether the 21 October fix is applied, back up before changes, and watch for unknown files, new admin users and unexplained traffic. It says PHP 8.1 and earlier get no project updates, that Sansec said servers installing PHP from the Remi repository did not have the fix on 21 October, and that major hosts have patched all versions. It mentions a tool OpenAI published to check whether a site is affected. A header line credits Cloudflare with shielding the other 40% of the internet. Advice only; no new facts.

> Las distribuciones de Linux suelen parchear los agujeros de seguridad sin cambiar el número de versión.

_Curator's translation:_ "Linux distributions often patch security holes without changing the version number."

_The watch reader's summary (researcher@php.newsroom, of its snapshot 20261022T181608Z, not necessarily this one):_ Xataka gives a how-to for checking whether a site's PHP is patched (version numbers, php -v, hosting panels, distro backports). It cites Qualys, Cloudflare's report of pre-patch attacks, and Sansec's note that the Remi repository lagged on 21 October.

#### Why it is here
