-Make the body request limit a configurable
+Adds a new `security.actionBodySizeLimit` option to configure the maximum size of Astro Actions request bodies.
+
+This lets you increase the default 1 MB limit when your actions need to accept larger payloads. For example, actions that handle file uploads or large JSON payloads can now opt in to a higher limit.
+
+If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse.
+
+```js
+// astro.config.mjs
+export default defineConfig({
+  security: {
+    actionBodySizeLimit: 10 * 1024 * 1024 // set to 10 MB
+  }
+})
+```
