CVE-2026-95835

Description

A flaw was found in kitty. This vulnerability leads to information disclosure, allowing a local attacker to capture sensitive credentials, such as passwords, entered into terminal prompts. The issue arises because the application's askpass escape sequence handler fails to verify the ownership and permissions of shared memory objects. By displaying a malicious prompt through terminal output, an attacker sharing the local memory space can intercept and read the victim's secret response.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Application Data; Read Files or Directories

An attacker could read sensitive data, either by reading the data directly from a data store that is not restricted, or by accessing insufficiently-protected, privileged functionality to read the data.

Integrity

Technical Impact: Modify Application Data; Modify Files or Directories

An attacker could modify sensitive data, either by writing the data directly to a data store that is not restricted, or by accessing insufficiently-protected, privileged functionality to write the data.

Access Control

Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism

An attacker could gain privileges by modifying or reading critical data directly, or by accessing privileged functionality.

Availability

Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)

An attacker could gain unauthorized access to resources on the system and excessively consume those resources, leading to a denial of service.
