Attackers, including prompt-injected model turns, can pass identifiers like com.1Password.1Password to get_app_state and action tools to read accessibility trees, capture screenshots, and drive unlocked password manager interfaces.","state":0,"publishedAt":"2026-10-11T12:19:31.981+00:00","modifiedAt":"2026-10-13T17:01:12.777+00:00","affected":[{"ecosystem":"Vendor product","name":"open-computer-use","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"iFurySt\",\n                    \"product\": \"open-computer-use\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"1.0.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:github/iFurySt/open-codex-computer-use\",\n                    \"repo\": \"https://github.com/iFurySt/open-codex-computer-use\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.8,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://hackmd.io/@haind/rJHI_S6IiMl","https://github.com/iFurySt/open-codex-computer-use/blob/8a3a7dec06402db2d760368cb24676ad3ba42c49/packages/OpenComputerUseKit/Sources/OpenComputerUseKit/AppDiscovery.swift#L144-L198","https://github.com/iFurySt/open-codex-computer-use/blob/8a3a7dec06402db2d760368cb24676ad3ba42c49/packages/OpenComputerUseKit/Sources/OpenComputerUseKit/AppDiscovery.swift#L554-L572","https://github.com/iFurySt/open-codex-computer-use","https://www.vulncheck.com/advisories/open-computer-use-through-1.0.0-denylist-bypass-via-case-variant-bundle-id"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-108721","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108721","identifiers":["CVE-2026-108721"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
