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

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: High: The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques, for example, circumvention of address space randomization (ASLR) or data execution prevention (DEP) must be performed for the attack to be successful; Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
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: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the vulnerable system.
Vulnerable system availability: High: There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the Vulnerable System; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the Vulnerable System (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).
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.

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.

AI-suggested

To mitigate CVE-2025-13433, European organizations should first identify and inventory all systems running MuseHub 2.1.0.1567. Administrators should manually inspect the installation directories for unquoted paths and, if feasible, rename directories or executables to eliminate spaces or apply quotes in service configurations. Employing least privilege principles to limit the permissions of the Muse.Updater.exe service can reduce exploitation impact. Monitoring system logs and file system changes related to MuseHub directories can help detect attempted exploitation. Organizations should also consider isolating systems running MuseHub from critical network segments to contain potential breaches. Finally, maintain vigilance for vendor updates or community patches and plan for timely deployment once available.

Description

A security flaw has been discovered in Muse Group MuseHub 2.1.0.1567. The affected element is an unknown function of the file C:\Program Files\WindowsApps\Muse.MuseHub_2.1.0.1567_x64__rb9pth70m6nz6\Muse.Updater.exe of the component Windows Service. The manipulation results in unquoted search path. The attack is only possible with local access. A high complexity level is associated with this attack. The exploitability is described as difficult. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, the impact of CVE-2025-13433 includes potential local privilege escalation and arbitrary code execution on systems running the vulnerable MuseHub version. This could lead to unauthorized access to sensitive multimedia projects, intellectual property theft, or disruption of creative workflows. Given MuseHub's role in managing multimedia content, exploitation could compromise data integrity and availability, affecting production timelines and business continuity. The requirement for local access limits remote exploitation but increases risk in environments with shared workstations or insufficient endpoint security. Organizations in sectors such as media, entertainment, and digital content creation are particularly at risk. The lack of vendor response and patches increases the window of exposure, necessitating proactive mitigation. Additionally, compromised systems could serve as footholds for lateral movement within corporate networks, amplifying the threat.

Summary

CVE-2025-13433 is an unquoted search path vulnerability identified in Muse Group's MuseHub version 2.1.0.1567, specifically within the Muse.Updater.exe component running as a Windows service. An unquoted search path occurs when an executable path containing spaces is not enclosed in quotes, allowing Windows to incorrectly resolve the path and potentially execute malicious binaries placed in higher-priority directories in the search order. This vulnerability requires local access and low privileges but does not require user interaction or authentication beyond local presence. The attack complexity is high due to the need for local access and precise placement of malicious files. Exploitation could allow an attacker to execute arbitrary code with the privileges of the Muse.Updater.exe service, potentially leading to privilege escalation or system compromise. The vendor has not responded to disclosure requests, and no patches are currently available. The CVSS 4.0 score is 7.3 (high), reflecting the significant impact on confidentiality, integrity, and availability, combined with difficult exploitability. The vulnerability affects a specific version of MuseHub, a multimedia software platform used by creative professionals, which may be installed in environments with sensitive data or critical workflows.
