CVE-2026-54300: CWE-918: Server-Side Request Forgery (SSRF) in withastro astro
@astrojs/netlify is an adapter that allows Astro to deploy your hybrid or server rendered site to Netlify. Prior to 7.0.13, @astrojs/netlify converts Astro image.remotePatterns into Netlify Image CDN images.remote_images regular expressions with broader semantics than Astro's canonical matcher. A single wildcard hostname such as *.example.com is converted to an optional subdomain regex, so the apex host matches. A single wildcard pathname such as /ok/* is converted without end anchoring, so deeper paths match by prefix. This vulnerability is fixed in 7.0.13.
AI Analysis
Technical Summary
The vulnerability CVE-2026-54300 affects the @astrojs/netlify adapter for the Astro framework by improperly converting Astro image.remotePatterns into Netlify Image CDN regular expressions with overly broad matching semantics. This flaw allows apex hosts and deeper URL paths to match unexpectedly, enabling Server-Side Request Forgery (SSRF) attacks. The problem exists in all versions prior to 7.0.13 and is resolved in version 7.0.13. The CVSS 3.1 base score is 5.3, reflecting a medium severity impact with network attack vector, low complexity, no privileges required, and no user interaction needed.
Potential Impact
An attacker can exploit the SSRF vulnerability to cause the server to make unintended HTTP requests to arbitrary hosts or paths. This may lead to information disclosure or interaction with internal services accessible from the server. The impact is limited to confidentiality loss without integrity or availability effects, as indicated by the CVSS vector.
Mitigation Recommendations
Upgrade the @astrojs/netlify adapter to version 7.0.13 or later, where the vulnerability is fixed. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the version fix information.
