An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-42850 in the wild and no public exploit code.\n\nAffected product: kovidgoyal 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-2026-42850/ (Markdown: https://insights.sbomify.com/CVE-2026-42850/index.md)","id":"CVE-2026-42850","markdown":"https://insights.sbomify.com/CVE-2026-42850/index.md","name":"CVE-2026-42850","record":{"aliases":["DEBIAN-CVE-2026-42850","GHSA-p64q-59hq-5q65","UBUNTU-CVE-2026-42850"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Kitty terminal emulator","requires_auth":"none","summary":"Attackers can execute arbitrary shell commands on a victim's machine by sending specially crafted escape codes to a Kitty terminal session.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kitty","vendor":"kovidgoyal"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.0, it is possible to inject commands within the subshell through kitty error. A special escape code will make kitty return an error, this error is not escaped and will be correctly echoed back to the terminal with CRLF, as such it will be run by the shell in use. To exploit this bug, the victim must use a netcat or a similar program to connect to the attacker, or else listening for someone to connect. Once this condition is set, an attacker could pwn the computer of the victim using a special kitty's escape code that will run a command in the shell in use. Version 04.7.0 fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Kitty has a shell command injection","id":"CVE-2026-42850","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"@kitty-edit DCS + --color=geninclude vulnerable to Unauthenticated in-process RCE","id":"CVE-2026-42851"},"packages":[],"prev":{"headline":"authentik: Reflected XSS in SFE AutosubmitStage allows IDP account takeover","id":"CVE-2026-42849"},"products":["kitty"],"published":"2026-06-12","related":[{"cvss_score":9.9,"headline":"Kitty has a Heap Buffer Over-Read/Write via Integer Overflow in compose_rectangles Bounds Check","id":"CVE-2026-33642","kev_date_added":null,"published":"2026-05-19"},{"cvss_score":7.8,"headline":"@kitty-edit DCS + --color=geninclude vulnerable to Unauthenticated in-process RCE","id":"CVE-2026-42851","kev_date_added":null,"published":"2026-06-12"},{"cvss_score":7.6,"headline":"Kitty has an arbitrary file overwrite via symlink following in `kitten dnd` remote drop staging","id":"CVE-2026-54056","kev_date_added":null,"published":"2026-06-12"},{"cvss_score":7.5,"headline":"Kitty has a Heap Buffer Overflow in its Graphics Protocol Handler","id":"CVE-2026-33633","kev_date_added":null,"published":"2026-05-19"},{"cvss_score":7.3,"headline":"Kitty vulnerable to command injection via unsanitized OSC 21 query reply","id":"CVE-2026-54057","kev_date_added":null,"published":"2026-06-12"},{"cvss_score":5,"headline":"Kitty has an Arbitrary File Write via Symlink Race Condition in File Transmission Protocol","id":"CVE-2026-54055","kev_date_added":null,"published":"2026-06-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"total"},"state":"PUBLISHED","updated":"2026-06-16","vendors":["kovidgoyal"]},"summary":"Attackers can execute arbitrary shell commands on a victim's machine by sending specially crafted escape codes to a Kitty terminal session.","url":"https://insights.sbomify.com/CVE-2026-42850/"}
