CVE-2026-45136 · claude-code-cache-fix: Local code execution via Python triple-quote injection in tools/quota-statusline.sh
This page contains facts from public vulnerability sources. Check the original advisory before updating.
claude-code-cache-fix is a cache optimization proxy for Claude Code. From 3.5.0 to before 3.5.2, tools/quota-statusline.sh (introduced in v3.5.0) interpolates Claude Code's hook stdin payload directly into a Python triple-quoted string literal. A ''' byte sequence in any user-controlled field of the payload closes the literal early and lets following bytes execute as Python in the user's Claude Code process. This vulnerability is fixed in 3.5.2.
