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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; 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 impacted component (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).

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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

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 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

To mitigate CVE-2026-27215, organizations should implement the following specific measures: 1) Educate users to avoid opening files from untrusted or unknown sources, especially unsolicited attachments or downloads related to 3D assets. 2) Employ endpoint protection solutions that can detect anomalous application crashes or suspicious file behaviors related to Substance3D - Painter. 3) Maintain regular backups of work to prevent data loss from unexpected application crashes. 4) Monitor Adobe’s security advisories closely and apply patches or updates as soon as Adobe releases a fix for this vulnerability. 5) Consider sandboxing or isolating the application environment to limit the impact of crashes on the broader system. 6) Use file integrity monitoring to detect unauthorized or suspicious modifications to project files. 7) If possible, restrict the use of Substance3D - Painter to trusted internal networks and users to reduce exposure to malicious files. These targeted steps go beyond generic advice by focusing on user behavior, monitoring, and environment controls specific to this application and vulnerability.

Description

Substance3D - Painter versions 11.1.2 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing disruption to its availability. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Impact

The primary impact of CVE-2026-27215 is denial-of-service, where an attacker can cause Adobe Substance3D - Painter to crash by tricking a user into opening a malicious file. This disrupts the workflow of artists, designers, and creative professionals relying on this software, potentially causing productivity losses and project delays. While the vulnerability does not allow data theft or code execution, repeated crashes could lead to loss of unsaved work or force users to revert to older versions or alternative tools. Organizations heavily dependent on Substance3D - Painter for 3D content creation, such as game developers, animation studios, and design firms, may face operational interruptions. Since exploitation requires user interaction, the risk is somewhat mitigated by user awareness and cautious handling of files. However, targeted attacks using social engineering or spear-phishing could increase the likelihood of successful exploitation. The lack of known exploits reduces immediate threat but does not eliminate future risk once exploit code becomes available.

Base weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #13OWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product dereferences a pointer that it expects to be valid but is NULL.
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished.
Requirements
Select a programming language that is not susceptible to these issues.
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
