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

Description

An insecure permissions vulnerability exists in the ActivityMain component of the M66B/Marcel Bokhorst NetGuard no-root firewall (versionCode 2026080101/versionName 2.337). This flaw allows unauthorized attackers to force a device reset or cause a Denial of Service (DoS).

Impact

Unauthorized attackers can exploit insecure permissions to force a device reset or cause a Denial of Service, potentially disrupting device availability and user operations.

Summary

The vulnerability in the ActivityMain component of the specified NetGuard no-root firewall version involves insecure permissions that permit unauthorized actors to arbitrarily trigger a device reset or cause a Denial of Service condition. No CVSS score or detailed technical exploit information is provided. There is no indication of known exploitation in the wild or available patches.
