Summary
A sandbox bypass vulnerability was identified in the optional Twig safe mode feature (CMS_SAFE_MODE). Certain methods on the collect() helper were not properly restricted, allowing authenticated users with template editing permissions to bypass sandbox protections.
Workarounds
If upgrading immediately is not possible:
- Disable
CMS_SAFE_MODEif untrusted template editing is not required - Restrict CMS template editing permissions to fully trusted administrators only

Impact
- Bypass of Twig sandbox restrictions
- Only affects installations with
CMS_SAFE_MODEenabled (disabled by default) - Requires authenticated backend access with CMS template editing permissions
CVE-2026-22692 has a CVSS score of 4.9 (Medium). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.1.5, 3.7.13); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
The vulnerability has been patched in v4.1.5 and v3.7.13. All users who have enabled safe mode are encouraged to upgrade to the latest patched version.

- What is CVE-2026-22692? CVE-2026-22692 is a medium-severity security vulnerability in october/rain (composer), affecting versions >= 4.0.0, <= 4.1.4. It is fixed in 4.1.5, 3.7.13.
- How severe is CVE-2026-22692? CVE-2026-22692 has a CVSS score of 4.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of october/rain are affected by CVE-2026-22692? october/rain (composer) versions >= 4.0.0, <= 4.1.4 is affected.
- Is there a fix for CVE-2026-22692? Yes. CVE-2026-22692 is fixed in 4.1.5, 3.7.13. Upgrade to this version or later.
- Is CVE-2026-22692 exploitable, and should I be worried? Whether CVE-2026-22692 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-22692 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
