    Server-side Request Forgery (SSRF)

    @astrojs/internal-helpers is an Internal helpers used by core Astro packages.

    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the /_image endpoint. An attacker can access internal or unauthorized resources by submitting crafted URLs to the generated image optimization endpoint configured with output: server and utilizing default imageService: compile.

    Note:

    This was partially fixed by the patch for CVE-2025-58179. That fix blocks http://, https:// and //, but can be bypassed using backslashes (\); the endpoint still issues a server-side fetch.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade @astrojs/internal-helpers to version 0.7.3 or higher.

    <0.7.3

    Cross-site Scripting (XSS)

    @astrojs/internal-helpers is an Internal helpers used by core Astro packages.

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the /_image endpoint.

This can lead to the execution of arbitrary scripts in the context of the affected site if a user follows a crafted link.

    Note: This vulnerability is only exploitable in projects using the @astrojs/node adapter and on-demand rendering.

    How to fix Cross-site Scripting (XSS)?

    Upgrade @astrojs/internal-helpers to version 0.7.2 or higher.

    <0.7.2
