- Severity: CVSS 7.0 (High), CNA
- Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total

- Published: 2026-09-18 · Updated: 2026-10-01

## Affected

- Sublime HQ Pty Ltd Sublime Text 4: 4192
- Sublime HQ Pty Ltd Sublime Text 3: 3207

## Description

Sublime Text for Windows through Build 4192 (Sublime Text 4) and Build 3207 (Sublime Text 3) contains a local privilege escalation vulnerability that allows unprivileged local attackers to execute arbitrary code with elevated privileges by abusing the update staging mechanism. Attackers can place a malicious DLL in the user-writable staging directory under %LOCALAPPDATA%, mark it read-only to bypass cleanup, and have the elevated installer copy it into the protected installation directory, causing the DLL to execute in the context of any higher-privileged user who subsequently launches the application.
