Linux Distros Unpatched Vulnerability : CVE-2026-26982

high Nessus Plugin ID 326430

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- Ghostty is a cross-platform terminal emulator. Ghostty allows control characters such as 0x03 (Ctrl+C) in pasted and dropped text. These can be used to execute arbitrary commands in some shell environments. This attack requires an attacker to convince the user to copy and paste or drag and drop malicious text. The attack requires user interaction to be triggered, but the dangerous characters are invisible in most GUI environments so it isn't trivially detected, especially if the string contents are complex. Fixed in Ghostty v1.3.0. (CVE-2026-26982)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
