CVE-2026-25125 (opens in a new tab)How to fix?
Upgrade october/october to version 3.7.14, 4.1.10 or higher.
Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection in the INI settings parser when environment variable interpolation is processed via the parse_ini_string function. An attacker with Editor permissions can retrieve sensitive environment variables by injecting patterns such as ${APP_KEY} or ${DB_PASSWORD} into CMS page settings fields, which are then resolved and stored in the template. These values are subsequently exposed to the attacker upon reopening the page. This is only exploitable if cms.safe_mode is enabled and the attacker has authenticated backend Editor access.
Workaround
This vulnerability can be mitigated by restricting Editor tool access to fully trusted administrators only and ensuring database and cloud service credentials are not accessible from the web server's network.
