CVE-2026-111045— CLI Bridge: High-severity sandbox escape via dangling symlink

Quick assessment

Affected
anshupriyan cli-bridge
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

CLI Bridge 提供对工作区根目录内文件系统的访问权限。在 0.0.2 版本之前，若存在一个指向工作区根目录之外的悬空符号链接（dangling symlink），当 因目标不存在而抛出 错误时， 会被绕过。此时，回退机制仅解析父目录，并将符号链接路径本身判定为安全，导致 函数跟随该链接，从而能够向工作区根目录之外写入任意文件。该问题已在 0.0.2 版本中修复。

Vulnerability Title
CLI Bridge: High-severity sandbox escape via dangling symlink
Source: CVE Program / CVE List V5
Vulnerability Description
CLI Bridge provides filesystem access within a workspace root. Prior to 0.0.2, a dangling symlink pointing outside the workspace root bypasses resolveSafePath when fs.realpathSync throws ENOENT for a nonexistent target. The fallback resolves only the parent directory and returns the symlink path as safe, so write_file follows the link and can write arbitrary files outside the workspace root. This issue is fixed in version 0.0.2.
