CVE-2026-55607 Claude Code: Sandbox Escape via Git Worktree Path Confusion Allows Unsandboxed Code Execution

Claude Code is an agentic coding tool. From 2.1.38 until 2.1.163, Claude Code's worktree handling allowed creation of worktrees named ".git" and navigation to worktrees outside the sandbox context, enabling git directory confusion attacks. By exploiting symlink manipulation and git fsmonitor...

CVE-2026-46406

CVE-2026-46406 affects @anthropic-ai/claude-code versions 2.1.59 through 2.1.128. The /copy command writes responses to a hardcoded, predictable path (/tmp/claude/response.md) with UID isolation, randomness, and symlink protections missing. The file is world-readable (0644) in a world-traversable...

CVE-2026-54371

A flaw was found in the attr package. This vulnerability allows a local attacker to perform a symlink traversal attack by replacing a pathname component with a symbolic link - either during directory hierarchy traversal by getfattr or during backup restoration by setfattr, which reads and resolve...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview acl is a None Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition. in the getfacl or setfacl process. An attacker can gain unauthorized access to files or escalate privileges by exploiting a race condition where a symbolic link replaces a...

Symlink Attack

Overview acl is a None Affected versions of this package are vulnerable to Symlink Attack. via the libacl functions. An attacker can gain unauthorized access to or modify access control lists by replacing a pathname component with a symbolic link, redirecting ACL read or write operations to...

CVE-2026-54371

The CVE affects the attr utilities (getfattr/setfattr) with versions before 2.6.0. Root cause is a symlink traversal during directory hierarchy traversal, enabling local privilege escalation when a privileged process uses getfattr/setfattr on attacker-controlled paths. The documents do not provid...
