In versions 1.0.0 through 4.0.18, the source.title and enclosure.type item fields in packages/astro-rss/src/index.ts are interpolated directly into XML template strings without XML-character escaping before being parsed by fast-xml-parser. Both fields are validated only as z.string(), placing no restriction on XML special characters. An attacker who controls these values can inject arbitrary XML into the generated RSS feed: a value containing &#34; can break out of an attribute (as with enclosure.type), and a value containing &lt;/source&gt; can close an element early and inject additional nodes (as with source.title). This corrupts feed structure, injects false metadata (for example, a fake &lt;link&gt; pointing to a malicious URL), and can cause feed readers to misparse or display attacker-controlled content. In SSR mode (output: &#39;server&#39;), the poisoned feed is served on every request to all subscribers. This issue has been fixed in version 4.0.19.</p> <p><strong>Affected:</strong> withastro astro</p> <p>Astro is a web framework for content-driven websites.
