PYSEC-2026-3433 yt-dlp: Arbitrary code execution via manifest downloads with aria2c

Summary If aria2c is used as an external downloader for a fragmented manifest format such as an HLS/DASH stream, yt-dlp passes insufficiently sanitized input to aria2c that allows an attacker to perform an arbitrary file write. On Windows platforms, this can lead to immediate arbitrary code...

PDM: Project-Local State and Config Writes Follow Symlinks

SummaryPDM writes several project-local state or configuration files without symlink protection. If a malicious repository places those files as symlinks, local PDM operations can overwrite the symlink targets.This creates an arbitrary file clobber primitive relative to the privileges of the...

PDM: Project-Controlled `.pdm-plugins` Content Executes Before CLI Parsing

SummaryPDM automatically loads project-local plugin paths from .pdm-plugins during Core initialization. Because this path is added via site.addsitedir, attacker-controlled .pth files inside the project plugin directory are processed and can execute Python code before normal CLI handling begins.Th...
