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 2026-10-25.

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

European organizations should implement the following specific measures: 1) Restrict and monitor the use of Adobe Substance3D - Painter to trusted users and environments, minimizing exposure. 2) Educate users on the risks of opening files from untrusted sources, emphasizing the need for caution with files received via email or external media. 3) Employ application whitelisting and sandboxing to limit the impact of malicious files. 4) Monitor network and endpoint logs for unusual activity related to Substance3D - Painter processes. 5) Coordinate with Adobe for timely updates and patches; apply them promptly once available. 6) Use Data Loss Prevention (DLP) tools to detect potential leakage of sensitive data. 7) Implement strict access controls and segmentation for systems running this software to reduce lateral movement in case of compromise. 8) Consider file integrity monitoring on directories where Substance3D - Painter project files are stored to detect unauthorized modifications.

Description

Substance3D - Painter versions 11.0.2 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 impact of this vulnerability depends on the extent of Adobe Substance3D - Painter usage within creative, design, gaming, and media production sectors. Disclosure of sensitive memory could lead to leakage of proprietary design assets, intellectual property, or user credentials stored in memory, potentially resulting in competitive disadvantage or data breaches. Since exploitation requires user interaction and opening a malicious file, targeted spear-phishing or supply chain attacks could be vectors. Organizations handling sensitive or regulated data (e.g., GDPR-protected personal data) could face compliance risks if confidential information is exposed. The medium severity score indicates a moderate risk, but the confidentiality impact is high, which is critical for industries relying on confidentiality of digital assets. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

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.
