{"id":"CVE-2026-45035","state":"PUBLISHED","title":"Tabby: RCE via `tabby://run` URL Scheme","description":"Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.233, Tabby registers itself as the handler for the tabby:// URL scheme on all platforms. The URL scheme handler supports a run command that directly executes OS commands with no user confirmation, sanitization, or sandboxing. An attacker can craft a malicious link (tabby://run?command=...) and deliver it via a website, email, chat message, or any other medium. When a victim clicks the link, the OS launches Tabby which immediately spawns the specified command as a child process with the user's full privileges. This is a zero-click-after-link-visit RCE vulnerability. This vulnerability is fixed in 1.0.233.","publishedAt":"2026-05-15T16:41:11.422Z","updatedAt":"2026-05-21T03:55:17.500Z","severity":{"score":9.4,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["Eugeny tabby"],"affected":[{"vendor":"Eugeny","product":"tabby","versions":[{"version":"< 1.0.233","status":"affected"}]}],"references":["https://github.com/Eugeny/tabby/security/advisories/GHSA-hf8h-rjrf-3jg6"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/45xxx/CVE-2026-45035.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-45035","state":"PUBLISHED","datePublished":"2026-05-15T16:41:11.422Z","dateUpdated":"2026-05-21T03:55:17.500Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-08T16:58:28.897Z"},"containers":{"cna":{"title":"Tabby: RCE via `tabby://run` URL Scheme","descriptions":[{"lang":"en","value":"Tabby (formerly Terminus) is a highly configurable terminal emulator.
