Release notes

Sourced from astro's releases.

astro@6.3.3

Patch Changes

• #16737 bd84f33 Thanks @​matthewp! - Fixes a reflected XSS vulnerability where slot names on hydrated components were not HTML-escaped in SSR output

astro@6.3.2

Patch Changes

• #16675 11d4592 Thanks @​ascorbic! - Fixes a regression where Astro.cache was undefined when experimental.cache was not configured.

  The previous documented behavior is for Astro.cache to always be defined as a no-op shim: cache.set() warns once, cache.invalidate() throws and cache.enabled can be used to gate. This allows library and user code can call cache methods without conditional checks. The cache provider registration was being gated at the call site on experimental.cache being configured, which meant the disabled shim branch inside the provider was unreachable and the Astro.cache getter was never attached to the context.

• #16691 0f0a4ce Thanks @​matthewp! - Fixes HTMLElement is not defined error during HMR when using components with client-side scripts (e.g. Starlight <Tabs>) and the Cloudflare adapter

• #16562 07529ec Thanks @​matthewp! - Fixes non-prerendered routes failing when a dynamic prerendered route exists in the same project with prerenderEnvironment: 'node'

• #16638 272185b Thanks @​ematipico! - Fixes a bug where the Astro compiler wasn't freed at the end of the build. After the fix, the memory used by the compiler is now correctly freed at the end of the build.

• #16544 d365c97 Thanks @​matthewp! - Tightens isRemotePath() to reject control characters after a leading slash and fixes the dev image endpoint origin check

• #16685 889e748 Thanks @​farrosfr! - Improve validation messages for security.csp.directives when script-src or style-src are incorrectly placed in the directives array.

• #16605 772f13a Thanks @​rururux! - Fixes assetsPrefix not being available on build from astro:config/server.

• #16556 f38dec7 Thanks @​matthewp! - Rejects double-encoded URL paths with a 400 response instead of silently falling back to partial decoding

• #16659 38bcb25 Thanks @​jsparkdev! - Fixes & characters appearing as raw entity strings (e.g. &[#38](https://github.com/withastro/astro/tree/HEAD/packages/astro/issues/38);) in <meta> tags when viewed in link previews or raw HTML.

• Updated dependencies [d365c97, 9256345]:

  • @​astrojs/internal-helpers@​0.9.1
  • @​astrojs/markdown-remark@​7.1.2
