CVE-2026-95835 Vulnerability Summary

CVE-2026-95835: Missing Authorization in the askpass escape code handler in kitty from 0.25.0 before 0.49.0 allows a local user other than the one running the terminal to obtain the text typed into a prompt that kitty itself displays, because handle_remote_askpass() in kitty/window.py opens the POSIX shared memory object named in the escape code, parses a prompt definition out of it, and writes the user's answer back into an object of that same name, without at any point checking that the object is owned by the user running kitty or that its permissions exclude other users. The equivalent consumer of the same SharedMemory class in the ssh kitten performs exactly that check; the askpass path did not. The handler is reached through a device control string processed from the byte stream of the window, so the attacker must also cause bytes of their choosing to be displayed by the victim's terminal. Where the POSIX shared memory namespace is shared between the two users, a second local user can create an object with permissions that allow the victim to read and write it, cause the victim's kitty to render a prompt of the attacker's choosing, including a masked password prompt, and read the typed secret back out of the object afterwards. The prompt text is additionally passed to the display without control character sanitisation, so it can overwrite the warning line kitty prints above it. The answer is written by reopening an object of that name when the user answers, rather than through the handle already held. This results in disclosure of a secret typed by the victim to a second local user, and does not require any privilege on the victim's account.

Assessing the Risk of CVE-2026-95835

Access Complexity Graph

The exploitability of CVE-2026-95835 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-95835

No exploitability data is available for CVE-2026-95835.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-95835, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

CAPEC Common Attack Pattern Enumeration and Classification

  • Exploitation of Thunderbolt Protection Flaws CAPEC-665 An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
