OpenClaw versions prior to 2026.2.14 contain a denial of service vulnerability in the extractArchive function within src/infra/archive.ts that allows attackers to consume excessive CPU, memory, and disk resources through high-expansion ZIP and TAR archives. Remote attackers can trigger resource exhaustion by providing maliciously crafted archive files during install or update operations, causing service degradation or system unavailability.

OpenClaw versions prior to 2026.2.15 contain a denial of service vulnerability in the web_fetch tool that allows attackers to crash the Gateway process through memory exhaustion by parsing oversized or deeply nested HTML responses. Remote attackers can social-engineer users into fetching malicious URLs with pathological HTML structures to exhaust server memory and cause service unavailability.

OpenClaw before 2026.5.6 contains an improper access control vulnerability in Mattermost event handlers that fails to validate channel type metadata. Attackers can bypass intended DM policy decisions by sending crafted Mattermost events missing channel type information to process restricted content.

OpenClaw before 2026.4.25 contains a scope containment bypass vulnerability in device re-pairing that allows authenticated operators to restore broader scopes than intended by submitting empty-scope re-pairing requests. Attackers can exploit this by sending re-pairing requests with empty scope sets to skip containment guards and retain unauthorized device access.

OpenClaw before 2026.4.8 contains an approval-timeout fallback mechanism that bypasses strictInlineEval explicit-approval requirements on gateway and node exec hosts. Attackers can exploit this timeout fallback to execute inline eval commands that should require explicit user approval, circumventing the intended security boundary.

OpenClaw before 2026.3.31 contains a fail-open vulnerability in the plugin installation flow where security scan failures do not block installation. Attackers can exploit scan failures to install untrusted plugins when operators proceed despite visible scan warnings.

OpenClaw before 2026.3.11 contains a credential fallback vulnerability where unavailable local gateway.auth.token and gateway.auth.password SecretRefs are treated as unset, allowing fallback to remote credentials in local mode. Attackers can exploit misconfigured local auth references to cause CLI and helper paths to select incorrect credential sources, potentially bypassing intended local authentication boundaries.
