{"id":"GHSA-wx4j-mvgx-mqwp","summary":"Satori-generated SVG has improper escaping","details":"## Impact\n\nSatori does not properly escape certain values before including them in generated SVG output. This can allow crafted values to be interpreted as SVG markup.\n\nThe impact depends on how the generated SVG is consumed.\n\n## Workaround\n\nNo complete workaround exists besides upgrading. Applications that cannot immediately upgrade should not render attacker-controlled content with Satori.","aliases":["CVE-2026-94545"],"modified":"2026-10-27T15:00:04.496894630Z","published":"2026-10-27T14:46:43Z","related":["CVE-2026-94545"],"database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-10-27T14:46:43Z","nvd_published_at":"2026-09-30T15:22:38Z","cwe_ids":["CWE-116"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/vercel/next.js/security/advisories/GHSA-vcvr-r3jv-pc5j"},{"type":"WEB","url":"https://github.com/vercel/satori/security/advisories/GHSA-wx4j-mvgx-mqwp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94545"},{"type":"WEB","url":"https://github.com/vercel/satori/pull/814"},{"type":"WEB","url":"https://github.com/vercel/next.js/commit/868fad38690d72088868f299fa2bef339b26838e"},{"type":"WEB","url":"https://github.com/vercel/satori/commit/26a52affc031216fee5882b6e965c8dbc7ac1782"},{"type":"WEB","url":"https://github.com/vercel/next.js/releases/tag/v16.3.6"},{"type":"PACKAGE","url":"https://github.com/vercel/satori"}],"affected":[{"package":{"name":"satori","ecosystem":"npm","purl":"pkg:npm/satori"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.27"},{"fixed":"0.33.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-wx4j-mvgx-mqwp/GHSA-wx4j-mvgx-mqwp.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N"}]}
