Summary CryptoJS.lib.WordArray.random in affected versions is not a cryptographically secure random number generator. Nominal requests for 128 or 256 bits of entropy produce effective search spaces of approximately 2^39 and 2^47 possibilities — small enough to enumerate on commodity hardware...

GHSA-F23P-VX2J-J53R Hono: `memo()` retains SSR output across requests, leading to cross-user data disclosure

Summary memo from hono/jsx retains the result of a server-side render and reuses it for later renders with comparator-equal props. Request-scoped values read inside the component take no part in that comparison, so a response can contain HTML rendered for another user's request. Details Component...

GHSA-79QM-7RJ5-M7R9 Hono: Proxy Helper does not remove response headers listed in the `Connection` header

Summary The Proxy Helper hono/proxy does not remove response headers named by the origin's Connection header. Headers that the origin marked as connection-scoped are therefore forwarded to clients. Details Per RFC 9110 Section 7.6.1, an intermediary must remove the header fields listed in a...

GHSA-HC8V-WWC9-VGXM go-git: Worktree operations may follow symlinks

Impact A symlink traversal issue in go-git could allow worktree operations to modify files outside the intended worktree path. The worktreeFilesystem wrapper rejected dangerous path strings, including paths containing .git, parent-directory components, or control characters. However, it did not...

GHSA-WVPP-8HX9-P66J GitPython: Unsafe git option guard bypass via split_single_char_options=False short-option token smuggling enables command execution

Summary The checkunsafeoptions guard can be bypassed on every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by combining a single-character kwarg with splitsinglecharoptions=False. The guard's candidate list omits the smuggled option, but transformkwarg...

GHSA-JM78-9FVV-MHGR GitPython: git-config OPTION-name injection via =/#/whitespace bypasses name validator, enabling forged core.sshCommand/hooksPath (RCE)

Summary GitPython's config-name validator only neutralizes CR/LF/NUL for the "option" label; it does not reject =, , ;, , , or whitespace in an option name. writesection writes the option name verbatim into the config file, so an option name such as sshCommand = touch is written as \tsshCommand =...

GHSA-HMQ2-W58F-27JC GitPython: Arbitrary Git Repository Creation Outside the Working Tree via Unvalidated .gitmodules Submodule Name in GitPython

Summary GitPython computes the on-disk location of a submodule's separate Git directory .git/modules/ from the submodule's .gitmodules section name with no validation. Because that name is fully attacker-controlled content of a cloned repository, a malicious repository can set a submodule name to...

GHSA-HH9P-6WH2-4MFC GitPython: Arbitrary file read via --pathspec-from-file in IndexFile.remove() and Head.checkout()

Summary IndexFile.remove and Head.checkout forward kwargs into git rm and git checkout with no guard. Passing --pathspec-from-file= together with --pathspec-file-nul makes Git treat the whole file as a single NUL-delimited pathspec, and the unmatched-pathspec error quotes it verbatim. GitPython...

GHSA-9RJ7-RF2P-W77R GitPython: Unguarded git option forwarding in Repo.init enables arbitrary command execution via --template clone hooks

Summary Repo.init forwards kwargs verbatim to git init with no unsafe-option guard and no allowunsafeoptions parameter. git init --template= copies /hooks/ into the new repo's .git/hooks, so an attacker-controlled template kwarg plants a hook that executes on the next git operation → arbitrary co...
