CVE-2026-27219: 
Adobe Substance 3D Painter vulnerability analysis and mitigation

CVE-2026-27219 is an Out-of-bounds Read vulnerability (CWE-125) in Adobe Substance 3D Painter that could lead to memory exposure and disclosure of sensitive information. It affects Substance 3D Painter versions 11.1.2 and earlier, with version 11.1.3 being the first patched release. Adobe disclosed and patched this vulnerability on March 10, 2026, as part of security bulletin APSB26-25. It carries a CVSS v3.1 base score of 5.5 (Medium) (Adobe Advisory).

The vulnerability is classified as CWE-125 (Out-of-bounds Read), where the application reads data beyond the allocated memory buffer boundaries during file parsing. Exploitation requires a local attack vector — an attacker must craft a malicious file and socially engineer a victim into opening it with Substance 3D Painter. No privileges are required by the attacker, but user interaction is mandatory. The out-of-bounds read can expose contents of process memory, potentially including sensitive data loaded by the application (Adobe Advisory).

Successful exploitation results in a high confidentiality impact — an attacker can read sensitive information from the application's memory — while integrity and availability are unaffected. The attack is limited to the local system scope, meaning the attacker cannot directly pivot to remote systems via this vulnerability alone. The primary risk is memory disclosure, which could expose credentials, cryptographic material, or other sensitive data processed by Substance 3D Painter (Adobe Advisory).

Adobe has released Substance 3D Painter version 11.1.3, which addresses this vulnerability. Users should upgrade to version 11.1.3 or later via the Creative Cloud desktop application or Adobe's official download channels. As a general precaution, users should avoid opening Substance 3D Painter project files received from untrusted or unknown sources (Adobe Advisory).

The Center for Internet Security (CIS) published an advisory noting multiple vulnerabilities in Adobe products patched in March 2026, including CVE-2026-27219, flagging potential for arbitrary code execution across the broader Adobe product set. Tenable also added detection coverage for this vulnerability. Community and media attention has been minimal given the medium severity rating and lack of active exploitation (CIS Advisory).
