CVE-2026-80432 Vulnerability Summary

CVE-2026-80432: Missing Authorization in the drop handling path of the drag and drop protocol in kitty from 0.47.0 before 0.49.0 allows a program writing to the terminal to obtain the contents of files dragged over the window even when the user never completes the drop, because drop_enqueue_request() in kitty/dnd.c serves a drag data request without first checking the drop state of the window, so a client that issues the request while a drag is merely hovering receives the data offered for the drag. In the same file, drop_left_child(), which runs when the drag leaves the window without a drop having occurred, releases the offered MIME list but retains the pending request state, the open file descriptor and its main loop transfer timer, the directory handles, the URI list and the pending MIME name, so a client can continue to read through a retained directory handle, and an in-flight file transfer continues to stream, when no drag is in progress. The file contents are read from the filesystem by the kitty process itself using the paths the drag source offered. This results in disclosure of the contents of files the user moved over the window without ever releasing them into it.

Assessing the Risk of CVE-2026-80432

Access Complexity Graph

The exploitability of CVE-2026-80432 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-2026-80432

No exploitability data is available for CVE-2026-80432.

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-2026-80432, 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

Below is the Impact Analysis for CVE-2026-80432, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

Confidentiality: None
CVE-2026-80432 does not compromise confidentiality.
Integrity: None
CVE-2026-80432 does not impact data integrity.
Availability: None
CVE-2026-80432 does not affect system availability.

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.
