Advisories for Npm/Trix package

The Trix editor, in versions prior to 2.1.18, is vulnerable to XSS when crafted HTML is pasted into the editor. The HTMLParser processed a mock attachment, a <span> carrying an empty data-trix-attachment="{}". The empty attachment object caused the element to bypass attachment handling, so its data-trix-attributes were applied to a plain string piece. The pre-2.1.18 StringPiece.fromJSON accepted the href without validation, so an attacker-supplied javascript: URI was carried into the …

The Trix editor, in versions prior to 2.1.18, is vulnerable to XSS when a crafted application/x-trix-document JSON payload is dropped into the editor in environments using the fallback Level0InputController (e.g., embedded WebViews lacking Input Events Level 2 support). The StringPiece.fromJSON method trusted href attributes from the JSON payload without sanitization. An attacker could craft a draggable element containing a javascript: URI in the href attribute that, when dropped into a …

The Trix editor, in versions prior to 2.1.17, is vulnerable to XSS attacks when a data-trix-serialized-attributes attribute bypasses the DOMPurify sanitizer. An attacker could craft HTML containing a data-trix-serialized-attributes attribute with a malicious payload that, when the content is rendered, could execute arbitrary JavaScript code within the context of the user's session, potentially leading to unauthorized actions being performed or sensitive information being disclosed.

The Trix editor, in versions prior to 2.1.16, is vulnerable to XSS attacks through attachment payloads. An attacker could inject malicious code into a data-trix-attachment attribute that, when rendered as HTML and clicked on, could execute arbitrary JavaScript code within the context of the user's session, potentially leading to unauthorized actions being performed or sensitive information being disclosed.

The Trix editor, in versions prior to 2.1.15, is vulnerable to XSS attacks when pasting malicious code. 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.

The Trix editor, versions prior to 2.1.11, is vulnerable to XSS when pasting malicious code in the link field.

The Trix editor, in versions prior to 2.1.9 and 1.3.3, is vulnerable to XSS + mutation XSS attacks when pasting malicious code.

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 https://github.com/basecamp/trix/security/advisories/GHSA-qjqp-xr96-cj99. In https://github.com/basecamp/trix/pull/1149, we added sanitation 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 …

The Trix editor, versions prior to 2.1.1, is vulnerable to arbitrary code execution when copying and pasting content from the web or other documents with markup into the editor. The vulnerability stems from improper sanitization of pasted content, allowing an attacker to embed malicious scripts which are executed within the context of the application. Vulnerable Versions: Up to 2.1.0 Fixed Version: 2.1.1 Vector: Bug 1: When copying content manipulated by …
