Summary
OpenClaw's sandbox skill mirroring path traversal vulnerability could write outside the sandbox workspace
Details

Overview

In affected versions, OpenClaw’s sandbox skill mirroring used the skill’s frontmatter name as part of the destination path when copying skills into the sandbox workspace. A crafted skill name containing traversal segments (for example ../) or an absolute path could cause the copy to write outside <sandbox_workspace>/skills/.

Impact

  • Files may be written outside the sandbox workspace root (within the permissions of the user running OpenClaw).

Attack Requirements

  • Attacker can provide a skill package (controls SKILL.md frontmatter).
  • Victim runs with sandbox enabled and skill mirroring into the sandbox workspace.

Affected Packages / Versions

  • openclaw (npm): < 2026.2.14

Fixed In

  • openclaw (npm): >= 2026.2.14

Fix Commit(s)

  • 3eb6a31b6fcf8268456988bfa8e3637d373438c2

OpenClaw thanks @1seal for reporting.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
