- Masato Kinugawa
- Impact
- high
Description
An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the resource://pdf.js origin. This could allow them to access cross-origin PDF content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions.
