CVE-2026-75137 Septeo IT Solutions CVE debrief

Who should care

Security teams responsible for Windows systems, particularly those using UpSignOn for authentication, should review and apply patches or updates to mitigate this vulnerability. Additionally, teams should monitor system logs for suspicious activity related to PROCESS_VM_READ permission usage and consider alternative authentication methods that do not store sensitive data in process memory. This vulnerability affects UpSignOn for Windows versions before 7.19.0 and has a medium-priority defensive review recommendation due to its local attack vector and sensitive data exposure.

Technical summary

UpSignOn for Windows before 7.19.0 contains a sensitive data exposure vulnerability that allows local attackers with PROCESS_VM_READ permission to recover cleartext vault data from process memory even after the application has been locked. The exposed data includes entry names, URLs, usernames, passwords, TOTP secrets, and notes. This vulnerability has a CVSS score of 6.9 and a severity rating of MEDIUM. Security teams should review and apply patches or updates to mitigate this vulnerability.
