PHP2Shell in Laragon: is it affected and how to fix it

How to check the PHP version Laragon uses

Run the command for your setup. A version at or above 8.2.35, 8.3.36, 8.4.27 or 8.5.12 in its branch is fixed; older branches are fixed only by a vendor build that says so.

dir C:\laragon\bin\php
C:\laragon\bin\php\<folder>\php.exe -v

The command-line php can differ from the PHP that serves the site. To be sure, check the web SAPI (a temporary phpinfo() page behind authentication, or the panel's PHP settings) and remove it afterwards. Our version checker compares a version number for you.

How to fix PHP2Shell in Laragon

Download PHP 8.3.36 for Windows from windows.php.net (Thread Safe for Apache, Non Thread Safe for Nginx/FastCGI) and unpack it into a new folder under C:\laragon\bin\php.
Select it in Menu → PHP → Version, carry over your php.ini changes, and restart all services.
If no vendor build exists, replacing the bundled PHP with an official fixed build of the same branch is the DIY route. Keep a backup of the old folder and your php.ini.
Restart the web server and re-check the version the web SAPI reports.

If you cannot patch yet

Set session.upload_progress.enabled = 0 where applications cannot override it (php.ini, php_admin_value in the FPM pool or Apache config), and restart PHP.
On PHP 8.5, set fatal_error_backtraces = 0.
PHP's interim advice also covers memory_limit and a low post_max_size; follow the remediation page exactly, because these settings only reduce some paths.
Restrict access (VPN, IP allowlist) or take the service offline if it runs PHP 8.1 or older with no vendor backport. WAF rules help but are not a fix.

FAQ

Is Laragon affected by PHP2Shell?

Likely affected: no vendor fix or statement found. Laragon 8.7.0 (August 2026) bundles PHP 8.3.33, which is vulnerable. We found no Laragon release or statement with fixed PHP.

Does updating Laragon itself fix CVE-2026-109618 and CVE-2026-109619?

Only if the update contains fixed PHP. PHP2Shell is a flaw in the PHP interpreter, so what matters is the PHP that Laragon runs on. Check the version after updating.

Which PHP versions fix PHP2Shell?

PHP 8.2.35, 8.3.36, 8.4.27 and 8.5.12, released 21 October 2026. PHP 8.1 and older get no release from the PHP project; only vendor builds with a backport (or a self-built source patch for 7.4, 8.0 and 8.1) fix them.

What if Laragon has no fix yet?

Keep its PHP-based web interface off the internet (VPN or IP allowlist), apply PHP's interim settings such as disabling session upload progress, and install the vendor update as soon as it ships. Interim settings reduce risk but are not a fix.
