{"id":"UBUNTU-CVE-2026-67214","details":"nanoid (Nano ID) before 3.3.16 and 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module (nanoid/non-secure). When these functions are given a negative size, the loop counter is decremented from a negative value and never reaches its termination condition, spinning indefinitely and hanging the calling thread. An application that passes an unvalidated, attacker-controlled negative size to these functions is exposed to a denial-of-service condition.","modified":"2026-09-02T19:41:32.015669521Z","published":"2026-07-29T14:16:00Z","upstream":["CVE-2026-67214"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-67214"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-67214"}],"affected":[{"package":{"name":"node-postcss","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-postcss?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.23-1","6.0.23-3"],"ecosystem_specific":{"binaries":[{"binary_name":"node-postcss","binary_version":"6.0.23-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67214.json"}},{"package":{"name":"node-postcss","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-postcss?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.2.1+~cs5.3.23-8","8.4.5+~cs7.1.51-2","8.4.6+~cs7.3.21-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-postcss","binary_version":"8.4.6+~cs7.3.21-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67214.json"}},{"package":{"name":"node-postcss","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-postcss?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.4.20+~cs8.0.23-1","8.4.31+~cs8.0.26-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-postcss","binary_version":"8.4.31+~cs8.0.26-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67214.json"}},{"package":{"name":"node-postcss","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-postcss?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.5.6+~cs9.3.28-1","8.5.8+~cs9.3.30-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-postcss","binary_version":"8.5.8+~cs9.3.30-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67214.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
