ansible-core: argument injection in ansible-galaxy role install leads to arbitrary code execution

A flaw was found in ansible-core. The ansible-galaxy role install command processes dependency specifications from a role's meta/requirements.yml file. Due to improper neutralization of argument delimiters, a malicious role author can inject arbitrary git configuration flags through the src field...

github.com/go-git/go-git: github.com/go-git/go-git/v5: go-git: Unauthorized file modification via directory traversal in reference names

A flaw was found in go-git, an extensible Git implementation library. Maliciously crafted reference names, which can contain directory-traversal sequences, are not properly sanitized. This vulnerability allows an attacker to write files outside of the intended reference storage directory,...

github.com/go-git/go-git/v5: go-git: Arbitrary file read/write via symbolic link resolution

A flaw was found in go-git, an extensible Git implementation library. Worktree operations, such as checkout, status, and add, resolve symbolic links within the working tree without proper boundary confinement. This allows a remote attacker to craft a malicious repository containing a symlink,...

GHSA-HR3M-4QWQ-3MGC GitHacker: Path traversal in ref/hash parsing enables existence oracle and hex-fragment exfiltration via malicious .git server

Summary GitHacker through 1.1.7 did not validate path segments parsed from attacker-controlled .git/HEAD before joining them onto its output directory. A malicious server could coerce GitHacker into reading arbitrary local files. Contents do not stream back wholesale, but the recovery loop turns...
