What is CVE-2025-22136?
CVE-2025-22136 is a high-severity code injection vulnerability in Eugeny tabby, published on 8 Jan 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.217 , Tabby enables several high-risk Electron Fuses, including RunAsNode, EnableNodeCliInspectArguments, and EnableNodeOptionsEnvironmentVariable. These fuses create potential code injection vectors even though the application is signed with hardened runtime and lacks dangerous entitlements such as com.apple.security.cs.disable-library-validation and com.apple.security.cs.allow-dyld-environment-variables. This vulnerability is fixed in 1.0.217.
Weakness: CWE-94
