Detailsinfo A vulnerability classified as problematic has been found in October CMS up to 3.7.13/4.1.9. Affected is the function parse_ini_string of the component Environment Variable Handler. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes: October is a Content Management System (CMS) and web platform. 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 to the attacker when the page was reopened. This could enable exfiltration of credentials and secrets (database passwords, AWS keys, application keys), potentially leading to further attacks such as database access or cookie forgery. The vulnerability is only relevant when cms.safe_mode is enabled, as direct PHP injection is already possible otherwise. This issue has been fixed in versions 3.7.14 and 4.1.10. If users are unable to immediately upgrade, they can workaround this issue 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. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-25125 since 01/29/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are necessary for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1592. Upgrading to version 3.7.14 or 4.1.10 eliminates this vulnerability.
