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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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

CVE published 26 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed

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 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.

AI-suggested

Until an official fix is available, users should consider implementing input validation or filtering on the Platform parameter to prevent path traversal characters and sequences. Monitoring for unusual access patterns related to this parameter is advisable. Avoid exposing the vulnerable versions in untrusted network environments.

Description

CVE-2026-7059 is a path traversal vulnerability in the 666ghj MiroFish application versions up to 0.1.2. It affects the get_simulation_posts function in the backend/app/api/simulation.py file, specifically the Query Parameter Handler component. An attacker can remotely manipulate the Platform argument to perform path traversal. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity. No official patch or remediation guidance is currently available, and no known exploits are reported in the wild.

Impact

Successful exploitation of this vulnerability could allow an attacker to read arbitrary files on the server hosting the vulnerable MiroFish application by manipulating the Platform parameter. This could lead to unauthorized disclosure of sensitive information. The CVSS score of 6.9 reflects a medium severity impact primarily due to confidentiality impact. There is no indication of integrity or availability impact. No known active exploitation has been reported.

Summary

The vulnerability CVE-2026-7059 exists in 666ghj MiroFish versions 0.1.0 through 0.1.2. It is a path traversal issue in the get_simulation_posts function within backend/app/api/simulation.py, where manipulation of the Platform query parameter allows an attacker to access unintended file system paths. The attack can be executed remotely without authentication. The CVSS 4.0 vector indicates network attack vector, low complexity, no privileges required, no user interaction, and low impact on confidentiality.
