Exploitation and automatability from CISA’s SSVC triage for GHSA-m5qg-jc75-4jp6.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-m5qg-jc75-4jp6 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
october/rain🐘october/rainReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
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.
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
Patches
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.
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

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for october/rain, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update october/rain to 4.1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m5qg-jc75-4jp6 is resolved across your whole dependency graph.
Workarounds
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-m5qg-jc75-4jp6 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-m5qg-jc75-4jp6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m5qg-jc75-4jp6 in your dependencies?
O3 Security finds GHSA-m5qg-jc75-4jp6 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
