Lifecycle Timeline
2DescriptionCVE.org
OpenClaw versions before 2026.6.1 contain a denial of service vulnerability where remote media URLs can trigger slow-read attacks that exhaust gateway worker resources. Attackers with access to configured input paths can supply remote media URLs that consume gateway resources and reduce availability.
AnalysisAI
Denial of service in OpenClaw gateway via slow-read attacks against remote media URL processing affects all versions before 2026.6.1. Attackers with access to configured input paths can supply crafted remote media URLs that hold gateway worker connections open indefinitely, gradually exhausting the worker pool and degrading availability for legitimate requests. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have been granted access to OpenClaw's 'configured input paths' - the application-level mechanism through which users submit remote media URLs for gateway processing. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.0 accurately reflects the constrained attack surface: AT:P (specific attack preconditions - access to configured input paths) and PR:L (low privilege required) prevent unauthenticated exploitation, meaningfully reducing the population of potential attackers compared to a fully open network attack. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privileged access to OpenClaw's media input paths submits a URL pointing to an attacker-controlled server configured to respond at one byte per second. The gateway opens a connection, begins reading the response, and holds the worker thread open for the full duration of the artificially slow transfer. … |
| Remediation | Upgrade to OpenClaw version 2026.6.1 or later, which resolves the resource exhaustion condition. … Detailed patch versions, workarounds, and compensating controls in full report. |
