{"apiVersion":"1.0","identifier":"CVE-2026-73648","description":"rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. From 1.0.3 until 1.7.1, Rails::HTML::PermitScrubber restricted SVG reference elements in SVG_ALLOW_LOCAL_HREF only when they used xlink:href, even though browsers also accept the plain href attribute. Applications with non-default allowed tags that included SVG use or feImage elements could therefore permit external references; a same-origin external SVG referenced by use could execute scripts in the sanitized document-s context, while feImage could load external images for tracking. Applications using the default allowed tags are not affected. This issue is fixed in version 1.7.1.","publishedAt":"2026-08-13T18:18:20","lastModifiedAt":"2026-08-13T19:17:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73648","cvssScore":5.1,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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","epssProbability":0.00396,"riskScore":0.53,"affectedProduct":"rails-html-sanitizer","affectedVersions":">=1.0.3,<1.7.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73648","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73648","en":"https://www.redsauce.net/en/cves/CVE-2026-73648","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73648","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73648","de":"https://www.redsauce.net/de/cves/CVE-2026-73648","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73648","el":"https://www.redsauce.net/el/cves/CVE-2026-73648"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73648"}}
