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-2025-27506 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 379,145 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.

Summary
The API endpoint related to the password reset function is vulnerable to Reflected Cross-Site-Scripting.
Details
Throughout the source-code analysis, it has been found that the endpoint /api/v1/db/auth/password/reset/:tokenId is vulnerable to Reflected Cross-Site-Scripting.
The flaw occurs due to implementation of the client-side template engine ejs, specifically on file resetPassword.ts where the template is using the insecure function “<%-“

which is rendered by the function renderPasswordReset:

PoC
Send the request below to a vulnerable instance:
/api/v1/db/auth/password/reset/asdsad%3C%2F%73%63%72%69%70%74%3E%3C%73%63%72%69%70%74%3E%61%6C%65%72%74%28%31%29%3C%2F%73%63%72%69%70%74%3E/
Impact

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update nocodb to 0.258.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-27506 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-2025-27506 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-27506. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
