In Astro versions 2.16.0 up to but excluding 5.15.5 which utilizeon-demand rendering, request headers `x-forwarded-proto` and `x-forwarded-port` are insecurely used, without sanitization, to build the URL. This has several consequences, the most important of which are: middleware-based protected route bypass (only via `x-forwarded-proto`), DoS via cache poisoning (if a CDN is present), SSRF (only via `x-forwarded-proto`), URL pollution (potential SXSS, if a CDN is present), and WAF bypass. Version 5.15.5 contains a patch."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":2.5}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-918"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:astro:astro:*:*:*:*:*:node.js:*:*","versionStartIncluding":"2.16.0","versionEndExcluding":"5.15.5","matchCriteriaId":"1C5C6C54-B40E-40C9-B3EF-905E2A559278"}]}]}],"references":[{"url":"https://github.com/withastro/astro/blob/970ac0f51172e1e6bff4440516a851e725ac3097/packages/astro/src/core/app/node.ts#L121","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/withastro/astro/blob/970ac0f51172e1e6bff4440516a851e725ac3097/packages/astro/src/core/app/node.ts#L97","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/withastro/astro/commit/dafbb1ba29912099c4faff1440033edc768af8b4","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/withastro/astro/security/advisories/GHSA-hr2q-hp5q-x767","source":"security-advisories@github.com","tags":["Exploit","Third Party Advisory"]}]}}]}
