CVE-2022-21668

pipenv is a Python development workflow tool. Starting with version 2018.10.9 and prior to version 2022.1.8, a flaw in pipenv's parsing of requirements files allows an attacker to insert a specially crafted string inside a comment anywhere within a requirements.txt file, which will cause victims who use pipenv to install the requirements file to download dependencies from a package index server controlled by the attacker. By embedding malicious code in packages served from their malicious index server, the attacker can trigger arbitrary remote code execution (RCE) on the victims' systems. If an attacker is able to hide a malicious `--index-url` option in a requirements file that a victim installs with pipenv, the attacker can embed arbitrary malicious code in packages served from their malicious index server that will be executed on the victim's host during installation (remote code execution/RCE). When pip installs from a source distribution, any code in the setup.py is executed by the install process. This issue is patched in version 2022.1.8. The GitHub Security Advisory contains more information about this vulnerability.

CVE-2024-47590

An unauthenticated attacker can create a malicious link which they can make publicly available. When an authenticated victim clicks on this malicious link, input data will be used by the web site page generation to create content which when executed in the victim's browser (XXS) or transmitted to another server (SSRF) gives the attacker the ability to execute arbitrary code on the server fully compromising confidentiality, integrity and availability.

CVE-2024-39899

PrivateBin is an online pastebin where the server has zero knowledge of pasted data. In v1.5, PrivateBin introduced the YOURLS server-side proxy. The idea was to allow using the YOURLs URL shortener without running the YOURLs instance without authentication and/or exposing the authentication token to the public, allowing anyone to shorten any URL. With the proxy mechanism, anyone can shorten any URL pointing to the configured PrivateBin instance. The vulnerability allowed other URLs to be shortened, as long as they contain the PrivateBin instance, defeating the limit imposed by the proxy. This vulnerability is fixed in 1.7.4.
