Code Injection in october/rain (CVE-2026-25125)
Summary
Code injection in october/rain (CVE-2026-25125). Confidential information can be exposed externally. Exploitable via cms.safe_mode. Mitigation: upgrade to 3.7.14 or later.
Original description
The description as published by the source.
A server-side information disclosure vulnerability was identified in the INI settings parser. PHP's parse_ini_string() function supports ${} syntax for environment variable interpolation. Attackers with Editor access could inject ${APP_KEY}, ${DB_PASSWORD}, or similar patterns into CMS page settings fields, causing sensitive environment variables to be resolved and stored in the template. These values were then returned to the attacker when the page was reopened.
Impact
- Exfiltration of sensitive environment variables (APP_KEY, DB credentials, AWS keys, etc.)
- Could enable further attacks: database access, cookie forgery, AWS resource access
- Requires authenticated backend access with Editor permissions
- Only relevant when
cms.safe_modeis enabled (otherwise direct PHP injection is already possible)
Patches
The vulnerability has been patched in v3.7.14 and v4.1.10. All users are encouraged to upgrade to the latest patched version.
Workarounds
If upgrading immediately is not possible:
- Restrict Editor tool access to fully trusted administrators only
- Ensure database and cloud service credentials are not accessible from the web server's network
