CVSS: 6.7EPSS: 0%CPEs: 2EXPL: 0CVE-2020-26231 – Bypass of fix for CVE-2020-15247, Twig sandbox escape
https://notcve.org/view.php?id=CVE-2020-26231
October is a free, open-source, self-hosted CMS platform based on the Laravel PHP Framework. A bypass of CVE-2020-15247 (fixed in 1.0.469 and 1.1.0) was discovered that has the same impact as CVE-2020-15247. An authenticated backend user with the cms.manage_pages, cms.manage_layouts, or cms.manage_partials permissions who would normally not be permitted to provide PHP code to be executed by the CMS due to cms.enableSafeMode being enabled is able to write specific Twig code to escape the Twig sandbox and execute arbitrary PHP. This is not a problem for anyone that trusts their users with those permissions to normally write & manage PHP within the CMS by not having cms.enableSafeMode enabled, but would be a problem for anyone relying on cms.enableSafeMode to ensure that users with those permissions in production do not have access to write & execute arbitrary PHP. Issue has been patched in Build 470 (v1.0.470) and v1.1.1. • https://github.com/octobercms/october/commit/d34fb8ab51108495a9a651b841202d935f4e12f7 https://github.com/octobercms/october/security/advisories/GHSA-r89v-cgv7-3jhx • CWE-862: Missing Authorization •
CVSS: 5.4EPSS: 0%CPEs: 1EXPL: 0CVE-2020-15249 – Stored XSS by authenticated backend user with access to upload files
https://notcve.org/view.php?id=CVE-2020-15249
October is a free, open-source, self-hosted CMS platform based on the Laravel PHP Framework. In October CMS from version 1.0.319 and before version 1.0.469, backend users with access to upload files were permitted to upload SVG files without any sanitization applied to the uploaded files. Since SVG files support being parsed as HTML by browsers, this means that they could theoretically upload Javascript that would be executed on a path under the website's domain (i.e. /storage/app/media/evil.svg), but they would have to convince their target to visit that location directly in the target's browser as the backend does not display SVGs inline anywhere, SVGs are only displayed as image resources in the backend and are thus unable to be executed. Issue has been patched in Build 469 (v1.0.469) & v1.1.0. • https://github.com/octobercms/library/commit/80aab47f044a2660aa352450f55137598f362aa4 https://github.com/octobercms/october/security/advisories/GHSA-fx3v-553x-3c4q • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2020-15248
October is a free, open-source, self-hosted CMS platform based on the Laravel PHP Framework. In October CMS from version 1.0.319 and before version 1.0.470, backend users with the default "Publisher" system role have access to create & manage users where they can choose which role the new user has.
