js-yaml: Exponential parsing time in flow collections leads to denial of service

Summary Parsing a small YAML document can take exponential time. An application that calls load or loadAll on untrusted input can be hung by a payload under 200 bytes. Details When an entry in a flow sequence turns out to be a key: value pair, the parser rewinds and parses that entry a second tim...

GitPython: Unsafe git option guard bypass via single-character kwarg value token smuggling enables arbitrary command execution

Summary GitPython's checkunsafeoptions guard the control introduced by CVE-2026-42215 / GHSA-2f96 and hardened since can be bypassed for every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by smuggling an option token inside the VALUE of a single-character...

GitPython: Incomplete unsafe_git_clone_options denylist omits --template enabling arbitrary command execution via clone hooks

Summary GitPython's unsafegitcloneoptions denylist omits --template. git clone --template= copies /hooks/ into the new repository and runs them post-checkout fires during clone, so a caller who can influence clone options can achieve arbitrary command execution in the default...

GitPython: Arbitrary file overwrite via git diff --output argument injection in Diffable.diff (key- and value-controlled)

Summary Diffable.diff forwards kwargs straight into diff/difftree with no checkunsafeoptions guard. Diffable is mixed into Commit, Tree, IndexFile, and Submodule, giving a broad surface. git diff --output= writes real patch content to an attacker-chosen path, enabling arbitrary file overwrite. Ro...
