Persistent Cross-site Scripting vulnerability in PrivateBin
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
In PrivateBin < v1.4.0 a cross-site scripting (XSS) vulnerability was found. The vulnerability is present since attachments with image preview got introduced in v0.21 of the project, which was at the time still called ZeroBin. The issue is caused by the fact that SVGs can contain JavaScript. This can allow an attacker to execute code, if the user opens a paste with a specifically crafted SVG attachment, and interacts with the preview image and the instance isn't protected by an appropriate content security policy.
