Summary
OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation
Details

Summary

Windows local-media handling accepted remote-host file URLs and UNC-style paths before local-path validation, so network-hosted file targets could be treated as local content.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: < 2026.3.22
  • Fixed: >= 2026.3.22
  • Latest released tag checked: v2026.3.23-2 (630f1479c44f78484dfa21bb407cbe6f171dac87)
  • Latest published npm version checked: 2026.3.23-2

Fix Commit(s)

  • 4fd7feb0fd4ec16c48ed983980dba79a09b3aaf5
  • 93880717f1cd34feaa45e74e939b7a5256288901

Release Status

The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

  • src/infra/local-file-access.ts now rejects remote-host file: URLs and UNC/network paths as non-local input.
  • src/media/web-media.ts, src/media-understanding/attachments.normalize.ts, and src/agents/sandbox-paths.ts all route through the shared local-file guard.

OpenClaw thanks @RacerZ-fighting, @Fushuling for reporting.

Taxonomy of the tags.




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.

Sightings

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.
