{"id":"UBUNTU-CVE-2026-120194","details":"A flaw was found in json-glib. The JSONPath slice evaluator used by json_path_query() can enter an infinite loop when given a slice expression with a negative step. An application that evaluates attacker-controlled JSONPath expressions can be forced into a hang, leading to a denial of service.","modified":"2026-11-04T03:30:35.365870233Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-120194"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-120194"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-120194"},{"type":"REPORT","url":"https://gitlab.gnome.org/GNOME/json-glib/-/issues/96"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-120194"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2564418"}],"affected":[{"package":{"name":"json-glib","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.4-2","1.1.2-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-json-1.0","binary_version":"1.1.2-0ubuntu1"},{"binary_version":"1.1.2-0ubuntu1","binary_name":"json-glib-tools"},{"binary_name":"libjson-glib-1.0-0","binary_version":"1.1.2-0ubuntu1"},{"binary_name":"libjson-glib-1.0-common","binary_version":"1.1.2-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-120194.json"}},{"package":{"name":"json-glib","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.8-1","1.4.2-2","1.4.2-3","1.4.2-3ubuntu0.18.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.4.2-3ubuntu0.18.04.1","binary_name":"gir1.2-json-1.0"},{"binary_name":"json-glib-tools","binary_version":"1.4.2-3ubuntu0.18.04.1"},{"binary_version":"1.4.2-3ubuntu0.18.04.1","binary_name":"libjson-glib-1.0-0"},{"binary_version":"1.4.2-3ubuntu0.18.04.1","binary_name":"libjson-glib-1.0-common"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-120194.json"}},{"package":{"name":"json-glib","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.4-2","1.4.4-2ubuntu1","1.4.4-2ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-json-1.0","binary_version":"1.4.4-2ubuntu2"},{"binary_version":"1.4.4-2ubuntu2","binary_name":"json-glib-tools"},{"binary_name":"libjson-glib-1.0-0","binary_version":"1.4.4-2ubuntu2"},{"binary_version":"1.4.4-2ubuntu2","binary_name":"libjson-glib-1.0-common"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-120194.json"}},{"package":{"name":"json-glib","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.2-1","1.6.2-1build1","1.6.6-1","1.6.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"gir1.2-json-1.0","binary_version":"1.6.6-1build1"},{"binary_name":"json-glib-tools","binary_version":"1.6.6-1build1"},{"binary_name":"libjson-glib-1.0-0","binary_version":"1.6.6-1build1"},{"binary_name":"libjson-glib-1.0-common","binary_version":"1.6.6-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-120194.json"}},{"package":{"name":"json-glib","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.0-1","1.8.0-2","1.8.0-2build1","1.8.0-2build2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.0-2build2","binary_name":"gir1.2-json-1.0"},{"binary_name":"json-glib-tools","binary_version":"1.8.0-2build2"},{"binary_name":"libjson-glib-1.0-0","binary_version":"1.8.0-2build2"},{"binary_name":"libjson-glib-1.0-common","binary_version":"1.8.0-2build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-120194.json"}},{"package":{"name":"json-glib","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.8+ds-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.10.8+ds-2","binary_name":"gir1.2-json-1.0"},{"binary_name":"json-glib-tools","binary_version":"1.10.8+ds-2"},{"binary_name":"libjson-glib-1.0-0","binary_version":"1.10.8+ds-2"},{"binary_name":"libjson-glib-1.0-common","binary_version":"1.10.8+ds-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-120194.json"}},{"package":{"name":"json-glib","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/json-glib?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.8+ds-1","1.10.8+ds-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.10.8+d
