{"apiVersion":"1.0","identifier":"CVE-2026-73428","description":"Trix is a what-you-see-is-what-you-get rich text editor for everyday writing. Prior to 2.1.18, Trix is vulnerable to stored cross-site scripting when crafted HTML is pasted into the editor. HTMLParser processes a mock attachment in a `<span>` with an empty `data-trix-attachment=-{}-` value, causing data-trix-attributes to be applied to a plain string piece. StringPiece.fromJSON accepts an unvalidated href, allowing a javascript: URI to enter the document model and serialized HTML and execute when another user renders and clicks the content. Applications that apply server-side HTML sanitization can neutralize the payload on save. This issue is fixed in version 2.1.18.","publishedAt":"2026-08-13T22:17:26","lastModifiedAt":"2026-08-14T18:19:09","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73428","cvssScore":4.6,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","epssProbability":0.00171,"riskScore":0.47,"affectedProduct":"Trix","affectedVersions":"<2.1.18","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73428","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73428","en":"https://www.redsauce.net/en/cves/CVE-2026-73428","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73428","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73428","de":"https://www.redsauce.net/de/cves/CVE-2026-73428","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73428","el":"https://www.redsauce.net/el/cves/CVE-2026-73428"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73428"}}
