OpenClaw < 2026.3.11 - Sandbox Boundary Bypass via Unanchored writeFile Commit Path
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
openclawnpmDescription
Summary
In affected versions of openclaw, the sandbox fs-bridge writeFile commit step used an unanchored container path during the final move into place. An attacker racing parent-path changes inside the sandbox could redirect the committed file outside the validated sandbox path.
Impact
This is a sandbox boundary bypass. In-sandbox code could win a time-of-check-time-of-use race and cause host-approved writeFile operations to land outside the validated writable path within the container mount namespace.
Affected Packages and Versions
- Package:
openclaw(npm) - Affected versions:
< 2026.3.11 - Fixed in:
2026.3.11
Technical Details
The hardening work for anchored remove, rename, and mkdir operations did not fully cover the writeFile commit path. The final mv still used the raw target path, leaving a race window between safety revalidation and the in-container commit step.
Fix
OpenClaw now anchors the writeFile commit path to the canonical parent directory before the final move. The fix shipped in [email protected].
Workarounds
Upgrade to 2026.3.11 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update openclaw to 2026.3.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32977 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-32977 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-32977. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-32977 in your dependencies?
O3 Security finds CVE-2026-32977 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
