Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-25125 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-25125 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-25125. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
