CVE-2026-32036: OpenClaw < 2026.2.26- Authentication Bypass via Encoded Dot-Segment Traversal in /api/channels

• Severity: high (CVSS 8.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-03-19 · updated 2026-06-17
• Weakness: CWE-289

Description

OpenClaw gateway plugin versions prior to 2026.2.26 contain a path traversal vulnerability that allows remote attackers to bypass route authentication checks by manipulating /api/channels paths with encoded dot-segment traversal sequences. Attackers can craft alternate paths using encoded traversal patterns to access protected plugin channel routes when handlers normalize the incoming path, circumventing security controls.

Affected products

• OpenClaw: before 2026.2.6 — fixed in 2026.2.6

How to fix

Upgrade to a fixed version: OpenClaw 2026.2.6. Check the vendor advisory for mitigations.
