OpenClaw: OpenShell FS bridge reads pin and verify the opened file before returning bytes

發布日:2026/5/4修改日:2026/5/12

描述

## Summary OpenShell FS bridge reads pin and verify the opened file before returning bytes ## Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.4.21 - Fixed version: 2026.4.22 ## Impact A time-of-check/time-of-use race around OpenShell sandbox filesystem reads could let a symlink swap cause bytes outside the intended mount root to be read. ## Fix OpenShell reads now open the file with no-follow semantics where available, validate the pinned file descriptor against the canonical mount root, reject unsafe hardlink/symlink cases, and use a strict fallback ancestor walk on platforms without fd-path readback. ## Fix Commit(s) - 95119017c847c737bd113f0bff728c4666d79c45 ## Verification - The fix commit is contained in the public v2026.4.22 tag. - [email protected] is published on npm and the compiled package contains the fix. - Focused regression coverage for this path passed before publication. Thanks @VladimirEliTokarev for reporting.
