{"id":"CVE-2026-108721","summary":"Open Computer Use through 1.0.0 Denylist Bypass via Case-Variant Bundle ID","details":"Open Computer Use through 1.0.0 on macOS contains an improper case sensitivity handling vulnerability that allows local MCP callers to bypass the password-manager denylist using case-variant bundle identifiers. 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.","modified":"2026-10-13T02:46:19.311436436Z","published":"2026-10-11T12:19:31.981Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108721.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-178"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108721.json"},{"type":"ADVISORY","url":"https://hackmd.io/@haind/rJHI_S6IiMl"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-108721"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/open-computer-use-through-1.0.0-denylist-bypass-via-case-variant-bundle-id"},{"type":"PACKAGE","url":"https://github.com/iFurySt/open-codex-computer-use"},{"type":"ARTICLE","url":"https://github.com/iFurySt/open-codex-computer-use/blob/8a3a7dec06402db2d760368cb24676ad3ba42c49/packages/OpenComputerUseKit/Sources/OpenComputerUseKit/AppDiscovery.swift#L144-L198"},{"type":"ARTICLE","url":"https://github.com/iFurySt/open-codex-computer-use/blob/8a3a7dec06402db2d760368cb24676ad3ba42c49/packages/OpenComputerUseKit/Sources/OpenComputerUseKit/AppDiscovery.swift#L554-L572"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ifuryst/open-codex-computer-use","events":[{"introduced":"0"},{"fixed":"8a3a7dec06402db2d760368cb24676ad3ba42c49"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.0.0"},{"fixed":"1.0.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.1","v0.2.0","v0.1.54","v0.1.53","v0.1.52","v0.1.51","v0.1.50","v0.1.49","v0.1.48","v0.1.47","v0.1.46","v0.1.45","v0.1.44","v0.1.43","v0.1.42","v0.1.41","v0.1.40","v0.1.39","v0.1.38","v0.1.37","v0.1.36","v0.1.35","v0.1.34","v0.1.33","v0.1.32","v0.1.31","v0.1.30","v0.1.29","v0.1.28","v0.1.27","v0.1.26","v0.1.25","v0.1.24","v0.1.23","v0.1.22","v0.1.21","v0.1.20","v0.1.19","v0.1.18","v0.1.17","v0.1.16","v0.1.15","v0.1.14","v0.1.13","v0.1.12","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","0.1.6","0.1.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-108721.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:L/VA:N/SC:N/SI:N/SA:N"}]}
