- 3.3LowSep 14, 2026Octobercms october DeserializationCVE-2026-49400October System provides the system module for October Content Management System. Prior to versions 3.7.17 and 4.2.21, the backend `SessionMaker` trait stored widget session state as `base64(serialize(...))` and consumed it with `unserialize()` without an `allowed_classes` restriction. Any code path that could write to a `widget.*` session key with attacker-controlled bytes could trigger PHP object injection the next time the widget read its session state, allowing instantiation of arbitrary clas

Versions prior to 3.7.17 and 4.2.21 have a vulnerability in the Twig sandbox security policy that allowed a chained bypass when `cms.safe_mode` is enabled. The Laravel session store was exposed to Twig with unrestricted method access, and raw SQL methods reachable through Eloquent's `__call` forwarding were not blocked across the full builder chain. When combined, a backend user with CMS markup editing access could

Versions prior to 3.7.14 and 4.1.10 contain a stored cross-site scripting (XSS) vulnerability in the SVG sanitization logic. The regex pattern used to strip event handler attributes (such as onclick or onload) could be bypassed using a crafted payload that exploits how the pattern matches attribute boundaries, allowing malicious SVG files to be uploaded through the Media Manager with embedded JavaScript. Exploitation could lead to pr

Versions prior to 3.7.14 and 4.1.10 contain a server-side information disclosure vulnerability in the INI settings parser. Because PHP's parse_ini_string() function supports ${} syntax for environment variable interpolation, attackers with Editor access could inject patterns such as ${APP_KEY} or ${DB_PASSWORD} into CMS page settings fields, causing sensitive environment variables to be resolved, stored in the template, and returned

Versions prior to 3.7.14 and 4.1.10 contain a stored cross-site scripting (XSS) vulnerability in the Event Log mail preview feature. When viewing logged mail messages, HTML content was rendered in an iframe without proper sandboxing, allowing JavaScript execution in the viewer's browser context. This issue has been fixed in versions 3.7.14 and 4.1.10. If users are unable to update immediately, workarounds include restricting mail tem

Versions prior to 3.7.14 and 4.1.10 contain a Stored Cross-Site Scripting (XSS) vulnerability in the Backend Editor Settings. The Markup Classes fields (used for paragraph styles, inline styles, table styles, etc.) did not sanitize input to valid CSS class name characters. Malicious values were rendered unsanitized in Froala editor dropdown menus, allowing JavaScript execution when any user opened a RichEditor. Exploitation could lea
