Exploitation evidence

Disclosed: evidence found.
Public on cve.org; its publication date is not in this record
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

An official fix is available from OpenClaw. Users should apply the update provided in the OpenClaw security advisory (https://github.com/openclaw/openclaw/security/advisories/GHSA-jq4x-98m3-ggq6) to remediate this vulnerability. Since authentication is required for exploitation, ensuring strong access controls and credential management is also advisable.

Description

This vulnerability allows remote attackers to disclose sensitive information on affected installations of OpenClaw. Authentication is required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 6.5. The following CVEs are assigned: CVE-2026-3689.

Impact

Successful exploitation allows an authenticated remote attacker to disclose sensitive information within the context of the OpenClaw service account. This could lead to exposure of confidential data but does not affect integrity or availability. There are no reports of active exploitation in the wild.

Summary

This vulnerability in OpenClaw involves insufficient validation of path parameters supplied to the canvas gateway endpoint. An authenticated remote attacker can exploit this path traversal flaw to access sensitive information accessible to the service account. The vulnerability is classified under CVE-2026-3689 with a CVSS score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). OpenClaw has released an official update to remediate the issue, as detailed in their security advisory.
