{"id":"GHSA-3jx4-q2m7-r496","aliases":[],"url":"https://o3.security/vulnerability/GHSA-3jx4-q2m7-r496","summary":"OpenClaw: Hardlink alias checks could bypass workspace-only file boundaries in specific configurations","details":"### Summary\nIn certain workspace-restricted configurations, OpenClaw could follow hardlink aliases inside the workspace that reference files outside the workspace boundary.\n\nBy default, `tools.fs.workspaceOnly` is off. This primarily affects deployments that intentionally enable workspace-only filesystem restrictions (and workspace-only `apply_patch` checks).\n\n### Impact\n- Confidentiality: out-of-workspace files could be read through in-workspace hardlink aliases.\n- Integrity: out-of-workspace files could be modified through in-workspace hardlink aliases.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published version at triage time: `2026.2.24`\n- Affected range: `<= 2026.2.24`\n- Planned patched version: `2026.2.25`\n\n### Fix Commit(s)\n- `04d91d0319b82fd4de91ed05e9fc5219ff2ab64e` (main)\n\n### Remediation\nOpenClaw now rejects hardlinked final-file aliases during workspace boundary validation for:\n- workspace-only path checks (`read` / `write` / `edit`)\n- workspace-only `apply_patch` read/write paths\n- sandbox mount-root path-safety checks\n\nRegression tests were added for `apply_patch`, workspace fs tools, and sandbox fs bridge hardlink alias escapes.\n\nOpenClaw thanks @tdjackey for reporting.","published":"2026-03-04T19:21:04Z","modified":"2026-03-04T19:31:14.688060Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.25"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/04d91d0319b82fd4de91ed05e9fc5219ff2ab64e","label":"openclaw/openclaw@04d91d0"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-3jx4-q2m7-r496"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/04d91d0319b82fd4de91ed05e9fc5219ff2ab64e"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-03-04T19:31:14.688060Z"}}
