CVE-2026-41335

Status: AnalyzedMedium (6.9)—

OpenClaw before 2026.3.31 contains an information disclosure vulnerability in the Control Interface bootstrap JSON that exposes version and assistant agent identifiers. Attackers can extract sensitive fingerprinting information from the Control UI bootstrap payload to identify system versions and agent configurations.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
