CVE-2026-53931 is a CWE-441 vulnerability in nocodb. No vendor fix is recorded yet; mitigation options are listed below.
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.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of nocodb has shipped for CVE-2026-53931 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
Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
