SCA: security update for astro (GHSA-8mv7-9c27-98vc)

medium Tenable Self-Hosted Container Security Plugin ID 445918

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Astro is a web framework for content-driven websites. From 7.0.0 until 7.0.6, the composable astro/hono
 pipeline installs security.checkOrigin only through the middleware() primitive, while actions() and
 pages() can dispatch to user code independently. Mounting actions() before middleware(), as in the
 examples/advanced-routing example and Cloudflare Hono documentation, allows cross-origin form-encoded
 action requests to execute before the origin check, and using pages() without middleware() drops the check
 for on-demand endpoints and pages. The flaw enables blind write-only cross-site request forgery using the
 victim's cookies against ActionHandler.handle and PagesHandler.handleWithErrorFallback when
 manifest.checkOrigin is enabled; the attacker can trigger a state-mutating action or endpoint handler but
 cannot read the cross-origin response. The default non-composable astro() pipeline is not affected. This
 issue is fixed in version 7.0.6. (CVE-2026-73423)

Solution

Update the astro library and its related packages to version 7.0.6 or later.
