CVE-2026-80430 Vulnerability Summary

CVE-2026-80430: Improper Link Resolution Before File Access in the drag source staging 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 create files and directories at paths outside the staging directory, because subdir_data_for_drag() in kitty/dnd.c resolves a descendant of the staged item tree by constructing a path string and opening it with safe_open(path, O_DIRECTORY | O_RDONLY, 0) rather than by walking the tree one component at a time, so a client that declares two entries with the same name, the first a symlink whose target is an arbitrary absolute path and the second a directory, causes mkdirat() to fail with EEXIST, which the code ignores, and causes the subsequent path resolution to follow the symlink and return a directory descriptor outside the staging directory, which is then passed as the dirfd argument to add_payload() and used for every further create operation on that item and its descendants. Entry names are sanitised against path separators and dot components, but symlink targets are not validated. Files are created with O_CREAT | O_WRONLY | O_EXCL at mode 0644, so existing files cannot be overwritten, and directories are created with mkdirat() at mode 0755, so the attacker can create intermediate directories that did not previously exist. This results in the creation of files and directories at any path writable by the user running kitty, provided the symlink target is an existing directory.

Assessing the Risk of CVE-2026-80430

Access Complexity Graph

The exploitability of CVE-2026-80430 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-2026-80430

No exploitability data is available for CVE-2026-80430.

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-2026-80430, 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

CWE Common Weakness Enumeration

CWE-59

CAPEC Common Attack Pattern Enumeration and Classification

  • Symlink Attack CAPEC-132 An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
  • Using Malicious Files CAPEC-17 An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files CAPEC-35 An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
  • Manipulating Web Input to File System Calls CAPEC-76 An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
