Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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
CVE-2025-23061 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 378,156 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
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
mongoosenpmDescription
Mongoose versions prior to 8.9.5, 7.8.4, and 6.13.6 are vulnerable to improper use of the $where operator. This vulnerability arises from the ability of the $where clause to execute arbitrary JavaScript code in MongoDB queries, potentially leading to code injection attacks and unauthorized access or manipulation of database data.
NOTE: this issue exists because of an incomplete fix for CVE-2024-53900.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mongoose, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update mongoose to 8.9.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-23061 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 CVE-2025-23061 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-23061. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect CVE-2025-23061
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id cve-2025-23061 -u https://target- Template
- Mongoose - NoSQL Injection
- Severity
- critical
- Impact
- Attackers can bypass authentication and execute arbitrary JavaScript code on MongoDB servers through nested $where operators in the populate() function, potentially accessing sensitive administrative data and compromising database integrity.
- Remediation
- Upgrade to Mongoose version 8.9.5 or later that properly blocks nested $where operators.
