{"id":"CVE-2026-72913","summary":"Kitty: Command injection into the child shell via chained @kitty-echo + @kitty-ssh DCS escape sequences","details":"Kitty is a cross-platform GPU based terminal. Prior to 0.48.2, the @kitty-echo and @kitty-ssh DCS handlers in kitty/window.py write unauthenticated data to the child shell's stdin, where handle_remote_echo accepts printable shell command characters and handle_remote_ssh calls get_ssh_data in kittens/ssh/utils.py, which emits a newline; chaining the handlers can execute attacker-controlled commands when a user displays untrusted terminal data. This issue is fixed in version 0.48.2.","aliases":["GHSA-ccp2-q4v6-rw94"],"modified":"2026-08-12T04:24:51.966771325Z","published":"2026-08-10T21:07:29.557Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-150","CWE-77","CWE-93"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72913.json"},"references":[{"type":"WEB","url":"https://github.com/kovidgoyal/kitty/releases/tag/v0.48.2"},{"type":"WEB","url":"https://sw.kovidgoyal.net/kitty/changelog/#id1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72913.json"},{"type":"ADVISORY","url":"https://github.com/kovidgoyal/kitty/security/advisories/GHSA-ccp2-q4v6-rw94"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72913"},{"type":"FIX","url":"https://github.com/kovidgoyal/kitty/commit/9dca948e9bec3c926ab3370f2cd10f9b9b10821f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kovidgoyal/kitty","events":[{"introduced":"0"},{"fixed":"9dca948e9bec3c926ab3370f2cd10f9b9b10821f"},{"fixed":"2cb1d95c3accadd536bd66ba6bda044973440177"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.48.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.47.0","v0.48.1","v0.48.0","v0.47.4","v0.47.3","v0.47.2","v0.47.1","v0.46.2","v0.46.1","v0.46.0","nightly","v0.45.0","v0.44.0","v0.43.1","v0.43.0","v0.42.2","v0.42.1","v0.42.0","v0.41.1","v0.41.0","v0.40.1","v0.40.0","v0.39.1","v0.39.0","v0.38.1","v0.38.0","v0.37.0","v0.36.4","v0.36.3","v0.36.2","v0.36.1","v0.36.0","v0.35.2","v0.35.1","v0.35.0","v0.34.1","v0.34.0","v0.33.1","v0.33.0","v0.32.2","v0.32.1","v0.32.0","v0.31.0","v0.30.1","v0.30.0","v0.29.2","v0.29.1","v0.29.0","v0.28.1","v0.28.0","v0.27.1","v0.27.0","v0.26.5","v0.26.4","v0.26.3","v0.26.2","v0.26.1","v0.26.0","v0.25.2","v0.25.1","v0.25.0","v0.24.4","v0.24.3","v0.24.2","v0.24.1","v0.24.0","v0.23.1","v0.23.0","v0.22.2","v0.22.1","v0.22.0","v0.21.2","v0.21.1","v0.21.0","v0.20.3","v0.20.2","v0.20.1","v0.20.0","v0.19.3","v0.19.2","v0.19.1","v0.19.0","v0.18.3","v0.18.2","v0.18.1","v0.18.0","v0.17.4","v0.17.3","v0.17.2","v0.17.1","v0.17.0","v0.16.0","v0.15.1","v0.15.0","v0.14.6","v0.14.5","v0.14.4","v0.14.3","v0.14.2","v0.14.1","v0.14.0","v0.13.3","v0.13.2","v0.13.1","v0.13.0","v0.12.3","v0.12.2","v0.12.1","v0.12.0","v0.11.3","v0.11.2","v0.11.1","v0.11.0","v0.10.1","v0.10.0","v0.9.1","v0.9.0","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.1","v0.7.0","v0.6.1","v0.6.0","v0.5.1","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.8","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-72913.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
