CVE-2026-92088 Oct 13, 19:21 HIGH This Week

Privilege escalation in upKeeper Instant Privilege Access through version 1.7.1 lets a local, authenticated low-privileged user gain elevated privileges by triggering improper handling of undefined values during input processing, with user interaction required for the escalation to succeed. The flaw carries a CVSS 4.0 base score of 8.6 (High) driven by total confidentiality, integrity and availability impact across both the vulnerable component and subsequent systems, although local access (AV:L), a valid low-privileged account (PR:L) and mandatory user interaction (UI:A) materially constrain real-world exploitability. There is no public exploit identified at time of analysis, and CISA SSVC assessment records Exploitation: none with Automatable: no, meaning scripted or fully autonomous attacks are not expected.
