11.1.0 crashed my store

(@alexp12)

Last night 11.1.0 pushed automatically and crashed my website with error 500. Had to downgrade to 11.1.0 to work again.

 WooCommerce 11.1.0 — fatal memory exhaustion on nearly every request

  Environment
  - WordPress 7.1, PHP 8.4.25, Apache 2.4.58 (Ubuntu) via mod_proxy_fcgi/PHP-FPM, MariaDB
  - WooCommerce updated 11.0.1 → 11.1.0 via a background/automatic update
  - WP_MEMORY_LIMIT was 256M before the incident
  - Redis object cache active (redis-cache 2.8.0 drop-in)

  Timeline
  - Plugin files rewritten at 2026-09-04 00:07:46 (auto-update to 11.1.0)
  - First fatal error 4 seconds later:
  PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 528384 bytes)
  in wp-includes/class-wp-hook.php on line 340
  - From then on, virtually every subsequent front-end and wp-admin request fatal errored (1,800+ occurrences in a few hours), most consistently:
  PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 262144 bytes)
  in wp-content/plugins/woocommerce/src/Internal/Features/FeaturesController.php on line 294
    with related fatals also seen in wp-includes/plugin.php, wp-includes/option.php, wp-content/object-cache.php, and
    woocommerce/includes/tracks/class-wc-site-tracking.php.

  Ruled out "just needs more memory"
  Raising WP_MEMORY_LIMIT from 256M → 512M did not resolve it — the site simply exhausted the new 512M ceiling too (Allowed memory size of
  536870912 bytes exhausted), pointing to unbounded/runaway memory growth rather than a legitimately higher peak requirement.

  Not request-specific — reproducible via WP-CLI bootstrap alone
  Even a plain wp plugin install ... --force (no HTTP request involved) triggered the same runaway growth and got OOM-killed by the kernel
  (confirmed via dmesg: Out of memory: Killed process ... (php) ... anon-rss:3026440kB) simply from bootstrapping WordPress with WooCommerce
  11.1.0 active. Using --skip-plugins (which prevents WC from loading during bootstrap) avoided the issue, confirming the leak triggers during
  WooCommerce's normal plugin-load path, not a specific endpoint.

  Resolution
  Downgrading to WooCommerce 11.0.1 (wp plugin install woocommerce --version=11.0.1 --force) immediately and completely resolved the issue — no
  code or config changes, no memory limit changes retained, site has been stable since.

  Active plugins alongside WooCommerce (for reproduction context):
  webappick-product-feed-for-woocommerce 8.0.11, seo-by-rank-math 1.0.277.2, redis-cache 2.8.0, simple-cloudflare-turnstile 1.42.1,
  google-site-kit 1.186.0, transbank-webpay-plus-rest 1.14.0, wpforms-lite 2.0.1.1, wp-mail-smtp 4.9.0, wp-super-cache 3.1.3, plus several small
  in-house plugins.
