SCA: security update for astro (GHSA-xr5h-phrj-8vxv)

medium Tenable Self-Hosted Container Security Plugin ID 441793

Description

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

 - Astro is a web framework. Astro versions prior to 6.1.10 used AES-GCM encryption to protect the
 confidentiality and integrity of server island props and slots parameters, but did not bind the ciphertext
 to its intended component or parameter type. An attacker could replay one component's encrypted props (p)
 value as another component's slots (s) value, or vice versa. Since slots contain raw unescaped HTML while
 props may contain user-controlled values, this could lead to XSS in applications. This occurs when the
 application uses server islands, two different server island components share the same key name for a prop
 and a slot, and an attacker has full control over the value of the overlapping prop (requires a
 dynamically rendered page). This vulnerability is fixed in 6.1.10. (CVE-2026-45028)

Solution

Update the astro library and its related packages to version 6.1.10 or later.
