CVE-2026-55696 1 Privatebin 1 Privatebin 2026-08-31 4.3 Medium
PrivateBin is an online pastebin where the server has zero knowledge of pasted data. Prior to 2.0.5, AttachmentViewer.setAttachment in js/privatebin.js uses getAttachmentMimeType to accept attacker-controlled MIME types and uses getBlobUrl to create a same-origin blob before setting attachmentLink's href for the Download attachment link. The SVG-only sanitization branch updates only the preview blob, so text/html, image/svg, application/xhtml+xml, and text/xml attachments can remain active in the download blob. On an instance with fileupload = true and a weakened, stripped, or absent Content Security Policy, an anonymous attacker can create such an attachment, and a victim who opens the link in a new tab causes inline JavaScript to execute in the PrivateBin origin. The script can read origin-scoped local storage and issue same-origin requests, including requests to applications co-hosted on the same domain. This issue is fixed in version 2.0.5.
CVE-2020-5223 1 Privatebin 1 Privatebin 2024-11-21 6.1 Medium
In PrivateBin versions 1.2.0 before 1.2.2, and 1.3.0 before 1.3.2, a persistent XSS attack is possible. Under certain conditions, a user provided attachment file name can inject HTML leading to a persistent Cross-site scripting (XSS) vulnerability. The vulnerability has been fixed in PrivateBin v1.3.2 & v1.2.2. Admins are urged to upgrade to these versions to protect the affected users.
