CVE-2026-91835 — OpenClaw ClawScan File Classifier static_scanner.go IsBinaryFile interpretation conflict

A vulnerability was detected in OpenClaw ClawScan up to 0.1.6. The impacted element is the function IsBinaryFile of the file internal/runner/static_scanner.go of the component File Classifier. The manipulation results in interpretation conflict. Attacking locally is a requirement. The exploit is now public and may be used. Upgrading to version 0.1.7 is sufficient to resolve this issue. The patch is identified as 04401337b3adb9343bd338b21e5e258bf49ca9c8. You should upgrade the affected component.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+1
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Openclaw ClawScan).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.

What should defenders know first?

CVE-2026-91835 is "OpenClaw ClawScan File Classifier static_scanner.go IsBinaryFile interpretation conflict", rated Low. It affects ClawScan (Openclaw); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 2.8 describes technical severity. EPSS 0.16% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
