{"id":"UBUNTU-CVE-2026-62996","details":"Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. From 5.0.0 until 5.8.4, Smarty's stream: resource-name handling does not adequately restrict which PHP stream wrappers and filter chains can be referenced from a template, allowing a php://filter-wrapped resource name to be used to read the contents of arbitrary local files accessible to the PHP process. An attacker able to author or influence a template's resource reference could exploit this to disclose sensitive file contents outside the intended template/config scope. This issue is fixed in version 5.8.4.","modified":"2026-08-13T00:10:36Z","published":"2026-08-07T16:17:00Z","upstream":["CVE-2026-62996"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-62996"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-62996"},{"type":"REPORT","url":"https://github.com/smarty-php/smarty/commit/3c9f77a2e06ce319ae0092496af32cc8f3adc52e"},{"type":"REPORT","url":"https://github.com/smarty-php/smarty/pull/1195"},{"type":"REPORT","url":"https://github.com/smarty-php/smarty/releases/tag/v5.8.4"},{"type":"REPORT","url":"https://github.com/smarty-php/smarty/security/advisories/GHSA-rjhh-76wf-8xmw"}],"affected":[{"package":{"name":"smarty3","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/smarty3?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.21-1","3.1.21-1ubuntu1","3.1.21-1ubuntu1+esm1","3.1.21-1ubuntu1+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.21-1ubuntu1+esm2","binary_name":"smarty3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty3","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/smarty3?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.31+20161214.1.c7d42e4+selfpack1-2","3.1.31+20161214.1.c7d42e4+selfpack1-3","3.1.31+20161214.1.c7d42e4+selfpack1-3ubuntu0.1","3.1.31+20161214.1.c7d42e4+selfpack1-3ubuntu0.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"smarty3","binary_version":"3.1.31+20161214.1.c7d42e4+selfpack1-3ubuntu0.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty3","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/smarty3?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.33+20180830.1.3a78a21f+selfpack1-1","3.1.34+20190228.1.c9f0de05+selfpack1-1","3.1.34+20190228.1.c9f0de05+selfpack1-1ubuntu0.1~esm1","3.1.34+20190228.1.c9f0de05+selfpack1-1ubuntu0.1","3.1.34+20190228.1.c9f0de05+selfpack1-1ubuntu0.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.34+20190228.1.c9f0de05+selfpack1-1ubuntu0.1+esm1","binary_name":"smarty3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty3","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/smarty3?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.39-2","3.1.39-2ubuntu1","3.1.39-2ubuntu1.22.04.1","3.1.39-2ubuntu1.22.04.2"],"ecosystem_specific":{"binaries":[{"binary_name":"smarty3","binary_version":"3.1.39-2ubuntu1.22.04.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty3","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/smarty3?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.48-1","3.1.48-1ubuntu0.24.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.48-1ubuntu0.24.04.1","binary_name":"smarty3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty4","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/smarty4?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.1-1","4.3.1-1ubuntu0.24.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"smarty4","binary_version":"4.3.1-1ubuntu0.24.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty3","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/smarty3?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.48-2","3.1.48-2build1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.48-2build1","binary_name":"smarty3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}},{"package":{"name":"smarty4","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/smarty4?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.5.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"smarty4","binary_version":"4.5.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62996.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC
