CVE-2026-49033 is a stack-based buffer overflow vulnerability in Labcenter Proteus 9.1_SP4_Build-42914. This vulnerability allows an attacker to execute arbitrary code by exploiting improper handling of stack memory. The CVSS 4.0 vector indicates local attack vector, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. No official remediation or patch has been announced by the vendor, and no known exploits have been reported.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system, potentially leading to full compromise of the application and underlying system. The high CVSS score reflects significant impact on confidentiality, integrity, and availability. However, exploitation requires local access and user interaction, which may limit the attack surface.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should limit local access to trusted users only and avoid executing untrusted files or inputs within the affected version. Monitor vendor communications for updates on patches or mitigations.
