CVE-2026-126364 Astro: Image endpoint in @astrojs/node can read files from a case-variant sibling of the output directory on case-sensitive filesystems

Astro is a web framework for content-driven websites. From 5.14.3 until 7.4.7, Astro's /image endpoint compared the requested local-image path with the build output directory without preserving case on case-sensitive filesystems. A sibling directory whose path differed from the output directory...

CVE-2026-126364

The Astro web framework (versions 5.14.3 through 7.4.7) contains a vulnerability in the /_image endpoint of the @astrojs/node adapter. The issue stems from a failure to preserve case sensitivity when comparing requested local-image paths against the build output directory on case-sensitive filesy...

CVE-2026-102984

A flaw was found in @astrojs/node. A remote attacker can cause a Denial of Service DoS by sending a specially crafted HTTP request containing a malformed port in the Host header. When static header handling is enabled, the adapter fails to catch the resulting URL parsing error, causing the Node...

CVE-2026-102984

Astro is a web framework for content-driven websites. Prior to 11.1.3, the @astrojs/node adapter builds a request URL from the Host header, and a malformed port can make that URL invalid. The recovery path reuses the same malformed host and throws an uncaught TypeError: Invalid URL before routing...
