CVE-2026-5493 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Labcenter Electronics Proteus PDSPRJ File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Labcenter Electronics Proteus. EPSS estimates a 0.27% chance of exploitation in the next 30 days.

Description

Labcenter Electronics Proteus PDSPRJ File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Labcenter Electronics Proteus. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PDSPRJ files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25718.
