CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N

Attack Vector: Local
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

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

Attack Vector: Local: The vulnerable component 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 remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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

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 2026-10-26.

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 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 the risk posed by CVE-2025-54204, European organizations should implement the following specific measures: 1) Restrict the use of Adobe Substance3D - Modeler to trusted users and environments, minimizing exposure to untrusted files. 2) Educate users on the risks of opening files from unknown or untrusted sources, emphasizing caution with email attachments and downloads. 3) Implement application whitelisting and sandboxing for Adobe Substance3D - Modeler to contain potential exploitation attempts and prevent unauthorized data access. 4) Monitor and control file sharing channels to detect and block malicious files targeting this vulnerability. 5) Maintain up-to-date backups and incident response plans tailored to potential data leakage incidents. 6) Engage with Adobe for timely updates and patches; once available, prioritize deployment of security updates for Substance3D - Modeler. 7) Use endpoint detection and response (EDR) tools to identify anomalous behaviors related to file opening or memory access within the application. 8) Consider network segmentation to isolate systems running Substance3D - Modeler from critical infrastructure to limit lateral movement in case of exploitation.

Description

Substance3D - Modeler versions 1.22.0 and earlier are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Impact

For European organizations, the primary impact of CVE-2025-54204 is the potential leakage of sensitive information through memory disclosure when users open malicious files in Adobe Substance3D - Modeler. Organizations in sectors such as media, entertainment, design, and digital content creation that rely on this software could face confidentiality breaches, potentially exposing intellectual property, proprietary designs, or personal data. While the vulnerability does not affect system integrity or availability, the exposure of sensitive memory contents could facilitate further attacks or data leaks. Given that exploitation requires user interaction, targeted phishing or social engineering campaigns could be used to deliver malicious files. The medium severity rating suggests a moderate risk; however, the impact could be significant for organizations handling sensitive or regulated data. Additionally, the lack of known exploits currently reduces immediate risk but does not eliminate the threat as attackers may develop exploits over time. European organizations must be vigilant, especially those with creative teams using Adobe Substance3D - Modeler, to prevent potential data leakage and comply with data protection regulations such as GDPR.

Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
