{"id":"UBUNTU-CVE-2026-72556","details":"A remote code execution vulnerability in ZoneMinder 1.39.17 allows any authenticated user to execute OS commands by exploiting a broken permission check in the Filter class. The canEdit() and canDelete() methods invoke nonexistent methods on the ZM\\User class, causing PHP __call() to return a truthy value that bypasses the permission check for all users. Any authenticated user can trigger filter-based OS command execution regardless of their assigned role.","modified":"2026-08-19T11:11:14Z","published":"2026-08-11T12:17:00Z","upstream":["CVE-2026-72556"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-72556"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-72556"},{"type":"REPORT","url":"https://github.com/ZoneMinder/zoneminder"}],"affected":[{"package":{"name":"zoneminder","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/zoneminder?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.28.1-8","1.29.0+dfsg-1","1.29.0+dfsg-1ubuntu1","1.29.0+dfsg-1ubuntu2","1.29.0+dfsg-1ubuntu2+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.29.0+dfsg-1ubuntu2+esm1","binary_name":"zoneminder"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-72556.json"}},{"package":{"name":"zoneminder","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/zoneminder?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.32.3-2build1","1.32.3-2ubuntu1","1.32.3-2ubuntu2","1.32.3-2ubuntu2+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.32.3-2ubuntu2+esm1","binary_name":"zoneminder"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-72556.json"}},{"package":{"name":"zoneminder","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/zoneminder?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.36.7+dfsg1-1","1.36.10+dfsg1-1","1.36.11+dfsg1-1","1.36.12+dfsg1-1","1.36.12+dfsg1-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"zoneminder","binary_version":"1.36.12+dfsg1-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-72556.json"}},{"package":{"name":"zoneminder","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/zoneminder?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.36.33+dfsg1-1build1","1.36.33+dfsg1-1build2","1.36.33+dfsg1-1build3","1.36.33+dfsg1-1build4"],"ecosystem_specific":{"binaries":[{"binary_version":"1.36.33+dfsg1-1build4","binary_name":"zoneminder"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-72556.json"}},{"package":{"name":"zoneminder","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/zoneminder?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.36.35+dfsg1-1","1.36.37+dfsg1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.36.37+dfsg1-1","binary_name":"zoneminder"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-72556.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
