SCA: security update for privatebin/privatebin (GHSA-r9x7-7ggj-fx9f)

medium Tenable Self-Hosted Container Security Plugin ID 436068

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PrivateBin is an online pastebin where the server has zero knowledge of pasted data. Starting in version
 1.7.7 and prior to version 2.0.3, dragging a file whose filename contains HTML is reflected verbatim into
 the page via the drag-and-drop helper, so any user who drops a crafted file on PrivateBin will execute
 arbitrary JavaScript within their own session (self-XSS). This allows an attacker who can entice a victim
 to drag or otherwise attach such a file to exfiltrate plaintext, encryption keys, or stored pastes before
 they are encrypted or sent. Certain conditions must exist for the vulnerability to be exploitable. Only
 macOS or Linux users are affected, due to the way the `>` character is treated in a file name on Windows.
 The PrivateBin instance needs to have file upload enabled. An attacker needs to have access to the local
 file system or somehow convince the user to create (or download) a malicious file (name). An attacker
 needs to convince the user to attach that malicious file to PrivateBin. Any Mac / Linux user who can be
 tricked into dragging a maliciously named file into the editor is impacted; code runs in the origin of the
 PrivateBin instance they are using. Attackers can steal plaintext, passphrases, or manipulate the UI
 before data is encrypted, defeating the zero-knowledge guarantees for that victim session, assuming
 counter-measures like Content-Security-Policy (CSP) have been disabled. If CSP is not disabled, HTML
 injection attacks may be possible - like redirecting to a foreign website, phishing etc. As the whole
 exploit needs to be included in the file name of the attached file and only affects the local session of
 the user (aka it is neither persistent nor remotely executable) and that user needs to interact and
 actively attach that file to the paste, the impact is considered to be practically low. Version 2.0.3
 patches the issue. (CVE-2025-64711)
