This link is maintained to preserve external references.\n\n## Original Description\nSvelteKit (@sveltejs/kit) before 3.0.0 contains a cross-site scripting vulnerability in prerendered pages because a cache-control header value set via setHeaders is inserted without escaping into a <meta http-equiv=\"cache-control\"> tag. An attacker who can influence that untrusted value at prerender time can break out of the content attribute and inject HTML or JavaScript that executes when users visit the page.","state":2,"publishedAt":"2026-10-21T03:32:18+00:00","modifiedAt":"2026-10-23T21:00:05.2880033+00:00","affected":[{"ecosystem":"npm","name":"@sveltejs/kit","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/sveltejs/kit/security/advisories/GHSA-27mw-82g8-phjj","https://nvd.nist.gov/vuln/detail/CVE-2026-114061","https://www.vulncheck.com/advisories/sveltekit-before-3.0.0-xss-via-cache-control-header-in-prerendered-pages"],"sourceUrl":"https://github.com/advisories/GHSA-85pr-xr59-r75h","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-85pr-xr59-r75h","identifiers":["GHSA-85pr-xr59-r75h"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
