brotli security fix the php team announces updated windows builds php 8 5 12 1 8 4 27 1 8 3 36 1 and 8 2 35 1 these builds include brotli 1 2 1 which fixes cve 2026 111497 an out of bounds write vulnerability in brotli decompression in php windows builds the vulnerable decoder can be reached through the curl extension when automatic http response decompression is enabled this is disabled by default in curl but applications and http client libraries can enable it the 1 suffix identifies a windows package rebuild with updated dependencies these builds use the same php source releases and the php runtime versions remain unchanged the updated packages are available on the downloads page 23 oct 2026 informational advisory session upload progress we suggest you set session upload_progress enabled 0 until the next regular bugfix release to fully protect from an unlikely rce vector this setting was already listed as a mitigation in the ghsa 6wmf 4rv5 p3rp advisory for cve 2026 109619 published on oct 21st 2026 if you applied it then keep it in place and no further action is needed the issue can only occur under an unusual combination of configuration and application code an application must set session serialize_handler to php_binary or php_serialize in its configuration and then switch it to php at runtime with ini_set before calling session_start session upload progress must also still be enabled applications that never change the serialize handler at runtime can keep the feature enabled since this setup is unlikely in practice we are handling it in the regular release cycle and will publish a full advisory for cve 2026 115560 with the next release 21 oct 2026 security advisory critical remote code execution vulnerabilities update now php 8 5 12 8 4 27 8 3 36 and 8 2 35 fix two critical vulnerabilities that can allow unauthenticated remote code execution all php users are strongly encouraged to update immediately who is at risk all php installations serving web requests including php fpm apache with mod_php php cgi frankenphp and litespeed we consider the risk highest for mod_php with a demonstrated exploit where an unauthenticated request can trigger the attack before any application code runs the vulnerabilities rce via oom corruption cve 2026 109618 ghsa w8hw w9fx j79w out of memory handling can interrupt php while internal request data is only partially initialized request cleanup may then treat the invalid data as valid rce via stale global state cve 2026 109619 ghsa 6wmf 4rv5 p3rp request owned internal state can survive after its backing memory has been freed a later request handled by the same worker may use that stale state before normal initialization resets it how to update update to php 8 5 12 8 4 27 8 3 36 or 8 2 35 source downloads are on our downloads page windows source and binaries are on the same page linux distributions and lts vendors received the patches in advance so check your vendor for updated packages php 8 1 and older no longer receive updates from the php project some distributions and lts vendors provide backported fixes so contact your vendor for details or upgrade to a supported version given the severity of these vulnerabilities the php security team provided minimal source backports for php 7 4 php 8 0 and php 8 1 to help people building from source or without access to an lts vendor if you cannot update immediately while only an update is a complete solution the following measures reduce exposure to specific attack paths but do not make an installation safe rce via oom corruption cve 2026 109618 set memory_limit 1 preferably in a way applications can t override such as php_admin_value in the fpm pool or apache configuration and check that no pool directory or application setting puts a finite limit back this removes the controllable php memory limit failure but an underlying allocation failure can still reach the vulnerable path set a low post_max_size for applications that don t require file uploads set post_max_size 8m if file uploads are necessary set post_max_size 32m keep upload_max_filesize below post_max_size consider enforcing limits at the web server or proxy level for decoded request size input field count multipart part count header count and nesting depth these limits must also cover requests without a usable content length use a container or cgroup limit as an availability boundary preferably with a policy that kills only the affected worker do not substitute rlimit_as or rlimit_data as these can cause the vulnerable allocation failure rce via stale global state cve 2026 109619 set session upload_progress enabled 0 and restart every worker use php ini an fpm pool or server configuration that applies before request parsing do not rely on ini_set or fpm user ini this blocks the confirmed session paths but not other variants on php 8 5 set fatal_error_backtraces 0 and restart every worker this blocks the confirmed fatal backtrace path only remove invalid or deprecated settings applied per request that emit diagnostics before initialization hiding diagnostics with error_reporting display_errors or does not help fix attacker reachable fatal errors and execution timeouts including failures in callbacks upload or import processing and cleanup the advisories linked above have the full technical details 21 oct 2026 php 8 6 0 rc4 available for testing the php team is pleased to announce the third release candidate of php 8 6 0 rc4 this continues the php 8 6 release cycle whose
