The Trix editor, versions prior to 2.1.4, is vulnerable to XSS when pasting malicious code. This vulnerability is a bypass of the fix put in place for GHSA-qjqp-xr96-cj99. In pull request 1149, sanitation was added for Trix attachments with a text/html content type. However, Trix only checks the content type on the paste event's dataTransfer object. As long as the dataTransfer has a content type of text/html, Trix parses its contents and creates an Attachment with them, even if the attachment itself doesn't have a text/html content type. Trix then uses the attachment content to set the attachment element's innerHTML. An attacker could trick a user to copy and paste malicious code that would execute arbitrary JavaScript code within the context of the user's session, potentially leading to unauthorized actions being performed or sensitive information being disclosed. This vulnerability was fixed in version 2.1.4.
CVE-2024-43368
This medium-severity CVE scores 6.5 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 61% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
