GHSA-hmcr-rmjq-47qr
GHSA-hmcr-rmjq-47qr is a CWE-441 vulnerability in nocodb. O3 Security confirms whether GHSA-hmcr-rmjq-47qr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
NocoDB: Server-Side Request Forgery via Spreadsheet Import Endpoint
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- 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.
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.
nocodbnpmDescription
Summary
The spreadsheet-import endpoint axiosRequestMake could be used as a generic
HTTP proxy. Before the fix it was reachable unauthenticated, and its
URL-extension allowlist was a regex tested against the full URL string, so
URLs whose query string ended in .csv (for example
https://example.com/robots.txt?.csv) satisfied the gate even though the
underlying request was for robots.txt.
Details
Three layers of protection now apply to the endpoint:
- The controller is decorated with
@UseGuards(DataApiLimiterGuard, GlobalGuard)and@Acl('fetchViaUrl'), so unauthenticated callers and callers without the editor role are rejected before the request body is processed. - The extension allowlist is tested against
url.pathnameonly. Callers can no longer satisfy the regex by appending a.csvsuffix to the query string. - The downstream axios call is wired to
useAgent(url)fromrequest-filtering-agent, which blocks RFC 1918, loopback, link-local, and other private destinations at the socket layer.
Impact
Unauthenticated callers could previously coerce the NocoDB process to issue HTTP requests on their behalf, including to internal services reachable from the host. With the auth gate in place and the pathname-anchored extension check combined with socket-layer destination filtering, the endpoint is no longer usable as a generic proxy and can no longer reach private ranges.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb. 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 nocodb has shipped for GHSA-hmcr-rmjq-47qr 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 GHSA-hmcr-rmjq-47qr 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 GHSA-hmcr-rmjq-47qr. 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-hmcr-rmjq-47qr in your dependencies?
O3 detects GHSA-hmcr-rmjq-47qr across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
