CVE-2026-33156: DLL Sideloading in ScreenToGif

• Severity: high (CVSS 7.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-03-20 · updated 2026-06-17
• Weakness: CWE-426

Description

ScreenToGif is a screen recording tool. In versions from 2.42.1 and prior, ScreenToGif is vulnerable to DLL sideloading via version.dll . When the portable executable is run from a user-writable directory, it loads version.dll from the application directory instead of the Windows System32 directory, allowing arbitrary code execution in the user's context. This is especially impactful because ScreenToGif is primarily distributed as a portable application intended to be run from user-writable locations. At time of publication, there are no publicly available patches.
