Greenshot had a code execution vulnerability. Here is what IT teams switched to.
CVE-2025-59050 — a high-severity deserialization flaw — was disclosed in September 2025. A PoC was published two days later. Many teams are still auditing or replacing Greenshot. Nabist covers everything Greenshot does, adds video recording and better annotations, and has no known CVEs.

Nabist vs. Greenshot: Side by Side
Greenshot does screenshots well. The gaps show up when you need more.
Greenshot features and status based on publicly available information as of early 2026.
Where Greenshot Wins (and Where It Falls Short)
An honest look at what Greenshot does well and where you will hit a wall.
Greenshot is genuinely good
Free, lightweight, and fast. The core screenshot workflow is solid: hotkey, region select, annotate, copy. If screenshots are your entire need, Greenshot earns its reputation and costs nothing.
No video at all
Greenshot has zero video capability. No recording, no trimming, no voiceover. The moment a teammate asks for a screencast walkthrough instead of a screenshot, you need a different tool entirely.
Practically Windows-only
There is a macOS App Store version, but it is a third-party port not maintained by the Greenshot team and last updated in 2019. Mixed-OS teams end up with a fragmented toolset.
A real CVE in 2025
CVE-2025-59050 (CVSS 8.4) allowed local code execution inside the signed Greenshot.exe process with no elevated privileges required. The fix is in v1.3.301. Nabist has no known CVEs.

"I used Greenshot for years and liked it. The problem was the moment I needed to record a walkthrough I had to switch to a different tool. Nabist handles both, and the annotation is genuinely better. $80 once was an easy call."Nabist user, software engineer
