{"id":"GHSA-2464-fhr4-w9xw","summary":"Next.js: Unauthenticated Remote Code Execution in Image Optimization API when SVG files are used","details":"## Impact\n\nA memory-related vulnerability has been discovered in an upstream library used for Image Optimization can lead to possible remote code execution (RCE) when Next.js runs on glibc-based Linux.\n\n## Workaround\n\nEnsure the version of `sharp` used by Next.js is greater than or equal to `0.35.5`. Fresh installs automatically get a fixed version of `sharp`.\nUpgrading Next.js to the patched versions will ensure package managers automatically provide a fixed version of `sharp` to Next.js.","modified":"2026-10-22T16:00:09.125335909Z","published":"2026-10-22T15:52:53Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-10-22T15:52:53Z","nvd_published_at":null,"cwe_ids":["CWE-1395"],"severity":"CRITICAL"},"references":[{"type":"WEB","url":"https://github.com/vercel/next.js/security/advisories/GHSA-2464-fhr4-w9xw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-96889"},{"type":"WEB","url":"https://github.com/vercel/next.js/commit/5e3b687b5edb868b064bdc058d768a7021e7f6ad"},{"type":"WEB","url":"https://github.com/vercel/next.js/commit/9571ec899f063df6533351bec390ccb2cc0af6a3"},{"type":"PACKAGE","url":"https://github.com/vercel/next.js"},{"type":"WEB","url":"https://github.com/vercel/next.js/releases/tag/v15.5.28"},{"type":"WEB","url":"https://github.com/vercel/next.js/releases/tag/v16.4.1"}],"affected":[{"package":{"name":"next","ecosystem":"npm","purl":"pkg:npm/next"},"ranges":[{"type":"SEMVER","events":[{"introduced":"10.0.0"},{"fixed":"15.5.28"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 15.5.27","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-2464-fhr4-w9xw/GHSA-2464-fhr4-w9xw.json"}},{"package":{"name":"next","ecosystem":"npm","purl":"pkg:npm/next"},"ranges":[{"type":"SEMVER","events":[{"introduced":"16.0.0"},{"fixed":"16.4.1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 16.4.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-2464-fhr4-w9xw/GHSA-2464-fhr4-w9xw.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"}]}
