From sanitize-html 2.17.7 until 2.18.0, an application configuration that permits namespace-prefixed SVG animation elements and the relevant URL-targeting attributes can bypass the SMIL URL protection because prefixed tag names do not match the unprefixed animation-element check. The bypass can rewrite a link destination to an unsafe URI after the sanitized SVG is rendered, with script execution occurring when a user activates the affected link; the default sanitizer configuration is not unconditionally affected. This issue is fixed in sanitize-html 2.18.0.","state":0,"publishedAt":"2026-10-20T17:17:36.78+00:00","modifiedAt":"2026-10-20T19:53:10.247+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N","score":3.7,"severity":"LOW"}],"references":["https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","https://github.com/apostrophecms/apostrophe/releases/tag/sanitize-html@2.18.0","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-374f-7chj-9948"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-113657","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-10-20T17:17:36.780","lastModified":"2026-10-20T19:53:10.247"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
