CVE-2026-75913

8.5 HIGH 0.5% exploit odds Fix listed Other Library

What it is

CodeWhale versions >= 0.3.27 and < 0.8.64 (published as deepseek-tui >= 0.3.27 and < 0.8.41 on npm and 0.3.27 through 0.8.41 on crates.io, and as codewhale / codewhale-tui >= 0.8.41 and < 0.8.64) contain an argument injection vulnerability in the git_show tool. The model-supplied rev parameter is passed unvalidated into the git show argv without an --end-of-options sentinel, so a value beginning with --output= is interpreted as a git flag. Because the tool is registered as auto-approved and advertised as read-only, an attacker (via a malicious repository combined with prompt injection) can cause an unprompted arbitrary file write at the privilege of the invoking user, targeting sensitive files such as ~/.ssh/authorized_keys, ~/.bashrc, or ~/.gitconfig. Fixed in codewhale / codewhale-tui 0.8.64 by adding rev validation; the deprecated deepseek-tui crate has no fixed release.
