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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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

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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

European organizations should immediately conduct a thorough audit of their 猫宁i Morning deployments to identify if the affected Shiro Configuration component is in use. Since no official patches or version details are available due to the rolling release model, organizations should: 1) Implement strict input validation and sanitization on all parameters that interact with file paths to prevent traversal sequences such as '../'. 2) Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attack patterns targeting the /index endpoint. 3) Restrict file system permissions to limit the web server's access to only necessary directories, minimizing potential damage from traversal. 4) Monitor logs for suspicious access patterns indicative of path traversal attempts. 5) Engage with the vendor for timely updates or patches and track their release channels closely. 6) Consider isolating the affected service in a segmented network zone to reduce lateral movement risk. 7) If possible, deploy runtime application self-protection (RASP) solutions to detect and block exploitation attempts in real time. These measures go beyond generic advice by focusing on compensating controls and proactive detection in the absence of immediate patches.

Description

A vulnerability was found in 猫宁i Morning up to bc782730c74ff080494f145cc363a0b4f43f7d3e. It has been classified as critical. Affected is an unknown function of the file /index of the component Shiro Configuration. The manipulation leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available.

Impact

For European organizations using 猫宁i Morning, this vulnerability poses a risk of unauthorized disclosure of sensitive configuration files or other critical data stored on affected servers. This could lead to leakage of credentials, internal network information, or other confidential data, undermining the confidentiality and integrity of systems. If attackers gain access to configuration files, they might escalate privileges or pivot within the network, increasing the risk of broader compromise. The remote and unauthenticated nature of the vulnerability means attackers can exploit it without prior access, raising the threat level. Organizations in sectors with strict data protection regulations such as GDPR may face compliance risks and potential fines if sensitive personal data is exposed. Additionally, disruption or manipulation of configuration files could impact service availability or reliability. Given the rolling release model and lack of clear patch information, organizations may find it challenging to verify if their deployments are secure, increasing exposure duration.
