Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 7 May 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: evidence found.
CVSS exploit maturity: proof of concept public
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), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 30 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.

AI-suggested

A patch identified by commit e8bd4e17e9428260f2161378356affc5ce90d6ed is available and should be applied to remediate this vulnerability. Due to the rolling release model of the product, users should update to the latest release that includes this patch. Patch status is not explicitly confirmed beyond this patch reference; therefore, users should verify with the vendor or official repository for the latest updates and apply them promptly.

Description

CVE-2026-8113 is a path traversal vulnerability in the 8421bit MiniClaw product affecting the isPathInside function in src/kernel.ts within the executeSkillScript component. This vulnerability allows remote attackers to manipulate file paths, potentially accessing unauthorized files. The vulnerability has a medium severity with a CVSS 4.0 score of 5.3. The product uses a rolling release model, so specific affected and patched version details are not available. A patch identified by commit e8bd4e17e9428260f2161378356affc5ce90d6ed is recommended to fix the issue. There are no known exploits in the wild at this time.

Impact

Successful exploitation of this vulnerability could allow remote attackers to perform path traversal, potentially accessing files outside the intended directory structure. This could lead to unauthorized information disclosure. The CVSS score of 5.3 (medium severity) reflects limited impact on confidentiality and no impact on integrity or availability. There are currently no known exploits in the wild.

Summary

The vulnerability CVE-2026-8113 in 8421bit MiniClaw involves a path traversal flaw in the isPathInside function of src/kernel.ts, part of the executeSkillScript component. This flaw allows remote attackers to manipulate file paths to access files outside the intended directory. The product's rolling release approach means version numbers are not fixed, but a patch commit e8bd4e17e9428260f2161378356affc5ce90d6ed addresses the issue. The CVSS 4.0 vector indicates network attack vector, low complexity, no privileges required, no user interaction, and low impact on confidentiality, with no impact on integrity or availability.
