5.18.1

Patch Changes

• Updated dependencies [c2cd371]:
  • @​astrojs/internal-helpers@​0.7.6
  • @​astrojs/markdown-remark@​6.3.11

5.18.0

Minor Changes

• #15589 b7dd447 Thanks @​qzio! - 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.

  // astro.config.mjs
  export default defineConfig({
    security: {
      actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB
    },
  });

Patch Changes

• #15594 efae11c Thanks @​qzio! - Fix X-Forwarded-Proto validation when allowedDomains includes both protocol and hostname fields. The protocol check no longer fails due to hostname mismatch against the hardcoded test URL.

5.17.3

Patch Changes

• #15564 522f880 Thanks @​matthewp! - Add a default body size limit for server actions to prevent oversized requests from exhausting memory.

• #15569 e01e98b Thanks @​matthewp! - Respect image allowlists when inferring remote image sizes and reject remote redirects.

5.17.2

Patch Changes

• c13b536 Thanks @​matthewp! - Improves Host header handling for SSR deployments behind proxies

5.17.1

Patch Changes

• #15334 d715f1f Thanks @​florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only
