go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, worktree operations (including checkout, status, and add) resolve symbolic links inside the working tree without confining resolution to the worktree boundary, so a maliciously crafted repository containing a symlink can cause go-git to read from or write to files outside the intended working …

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link("victim.secret", "/payload.tar.gz/evil_cwd_link") to resolve header.Linkname against the process current working directory for a Typeflag=TypeLink entry such as N…

Microsoft AVML before 0.17.0 could follow a symlink when opening a destination output path on Unix, allowing truncation/overwrite of the symlink target. The destructive effect is performed at open-time via O_TRUNC, and can happen before full input validation completes (“truncation-before-validation”).

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, with -l/--links, rclone serializes symlinks as .rclonelink text objects and recreates them on a local destination without validating the target, allowing an attacker-controlled remote to plant an escaping symlink and cause a following object write to land outside the desti…

DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location. The complete_table_name method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data directory can point to a table file at any path outside of the configured f_dir and f_dir_search directories. Callers of file-based drivers c…
