zrok copy writes attacker-controlled WebDAV paths outside the destination root

Summary Alice runs zrok2 copy from a WebDAV or zrok drive controlled by Bob into a local filesystem target. Bob returns a DAV href such as /../outside.txt. The sync pipeline stores that path in the source inventory and passes it to FilesystemTarget.WriteStream, which joins it with the target root...

OpenTelemetry eBPF Instrumentation: Log enricher writev path can overread and overwrite user buffers

Summary OBI's log enricher mishandles writev buffers by reading only the first iovec entry but using the total ioviter.count as the copy length. When log injection is enabled, a crafted multi-segment writev call can make OBI read and overwrite memory beyond the first segment. Details In...

When sed is invoked with both -i in-place edit and --follow-symlinks, the function opennextfile performs two separate, non-atomic filesystem operations on the same path: 1. resolves symlink to its target and stores the resolved path for determining when output is written, 2. opens the original...

UBUNTU-CVE-2026-31802

node-tar is a full-featured Tar for Node.js. Prior to version 7.5.11, tar npm can be tricked into creating a symlink that points outside the extraction directory by using a drive-relative symlink target such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x...

Important: nodejs24

Issue Overview: node-tar is a Tar for Node.js. The node-tar library = 7.5.2 fails to sanitize the linkpath of Link hardlink and SymbolicLink entries when preservePaths is false the default secure behavior. This allows malicious archives to bypass the extraction root restriction, leading to...

GHSA-4FQP-R85R-HXQH Copier safe template has arbitrary filesystem write access via directory symlinks when _preserve_symlinks: true

Impact Copier suggests that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like custom Jinja extensions which would require passing the --UNSAFE,--trust flag. As it turns out, a safe template can currently write to arbitrary directories outside the...
