CVE-2026-75913 is an argument-injection vulnerability in the auto-approved CodeWhale and codewhale-tui git_show tool in versions 0.8.41 through 0.8.63. The tool passes a model-supplied revision parameter to git show without validating it or placing Git’s end-of-options sentinel before it. A revision value beginning with an option prefix can therefore be parsed as a Git command-line option rather than as a revision. In particular, Git output-redirection options can be injected to write command output to an attacker-selected filesystem location. The tool’s auto-approved, read-only designation permits the operation without an explicit user approval prompt.

An argument-injection vulnerability in the auto-approved, nominally read-only git_show tool in CodeWhale/DeepSeek-TUI. An attacker can supply a --output=<path> value as the revision argument, causing git show to truncate and write attacker-controlled repository output to an arbitrary file writable by the invoking user. A malicious repository and prompt injection through AGENTS.md can trigger this without a user approval prompt.
An argument injection vulnerability in CodeWhale's git_show tool that can let an attacker trigger arbitrary file writes via a malicious rev parameter, potentially overwriting sensitive user files.
