Adobe has patched 11 vulnerabilities in Substance 3D Stager 3.1.8 and earlier.

All 11 CVEs carry the same 7.8 score. Adobe, the CVE numbering authority, rates each 7.8 (High) under CVSS 3.1. NVD has not yet published its own scores. The issues affect the same product range and share the same exploitation requirement.
Most flaws enable arbitrary code execution.

Most flaws enable arbitrary code execution. Ten of the CVEs describe stack-based buffer overflows or out-of-bounds write conditions. Successful exploitation grants code execution in the context of the current user.

One CVE involves an out-of-bounds read. CVE-2026-103840 allows an attacker to read past the end of an allocated memory structure when parsing a crafted file. The read can still lead to code execution under the same user context.
Successful exploitation grants code execution in the context of the current user.
Exploitation requires user interaction. Every listed vulnerability states that a victim must open a malicious file. No remote, unauthenticated vectors are described in the NVD records.
