It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-80430 in the wild and no public exploit code.\n\nAffected product: Kovid Goyal kitty. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-80430/ (Markdown: https://insights.sbomify.com/CVE-2026-80430/index.md)","id":"CVE-2026-80430","markdown":"https://insights.sbomify.com/CVE-2026-80430/index.md","name":"CVE-2026-80430","record":{"aliases":["DEBIAN-CVE-2026-80430","GHSA-phg7-mgrc-j9pj","UBUNTU-CVE-2026-80430"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"kitty terminal emulator","requires_auth":"none","summary":"A path traversal vulnerability in kitty allows a malicious program to create files and directories outside the intended staging directory via symlink manipulation.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Secur0","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Path traversal in kitty","id":"CVE-2026-80430","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Out-of-bounds write in the kitty text sizing protocol allows termination of the terminal process","id":"CVE-2026-80431"},"packages":[],"prev":{"headline":"ILIAS PHP Object Injection via Shibboleth Logout","id":"CVE-2026-80428"},"products":["kitty"],"published":"2026-09-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-25","vendors":["Kovid Goyal"]},"summary":"A path traversal vulnerability in kitty allows a malicious program to create files and directories outside the intended staging directory via symlink manipulation.","url":"https://insights.sbomify.com/CVE-2026-80430/"}
