Bumps astro from 5.12.3 to 5.15.9.

Release notes

Sourced from astro's releases.

astro@5.15.9

Patch Changes

  • #14786 758a891 Thanks @​mef! - Add handling of invalid encrypted props and slots in server islands.

  • #14783 504958f Thanks @​florian-lefebvre! - Improves the experimental Fonts API build log to show the number of downloaded files. This can help spotting excessive downloading because of misconfiguration

  • #14791 9e9c528 Thanks @​Princesseuh! - Changes the remote protocol checks for images to require explicit authorization in order to use data URIs.

    In order to allow data URIs for remote images, you will need to update your astro.config.mjs file to include the following configuration:

    // astro.config.mjs
    import { defineConfig } from 'astro/config';
    export default defineConfig({
    images: {
    remotePatterns: [
    {
    protocol: 'data',
    },
    ],
    },
    });

  • #14787 0f75f6b Thanks @​matthewp! - Fixes wildcard hostname pattern matching to correctly reject hostnames without dots

    Previously, hostnames like localhost or other single-part names would incorrectly match patterns like *.example.com. The wildcard matching logic has been corrected to ensure that only valid subdomains matching the pattern are accepted.

  • #14776 3537876 Thanks @​ktym4a! - Fixes the behavior of passthroughImageService so it does not generate webp.

  • Updated dependencies [9e9c528, 0f75f6b]:

    • @​astrojs/internal-helpers@​0.7.5
    • @​astrojs/markdown-remark@​6.3.9

astro@5.15.8

Patch Changes

  • #14772 00c579a Thanks @​matthewp! - Improves the security of Server Islands slots by encrypting them before transmission to the browser, matching the security model used for props. This improves the integrity of slot content and prevents injection attacks, even when component templates don't explicitly support slots.

    Slots continue to work as expected for normal usage—this change has no breaking changes for legitimate requests.

  • #14771 6f80081 Thanks @​matthewp! - Fix middleware pathname matching by normalizing URL-encoded paths

    Middleware now receives normalized pathname values, ensuring that encoded paths like /%61dmin are properly decoded to /admin before middleware checks. This prevents potential security issues where middleware checks might be bypassed through URL encoding.
