## What is CVE-2026-53931?

CVE-2026-53931 is a medium-severity server-side request forgery vulnerability in nocodb, published on 23 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, 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 satisfies the gate even though the
underlying request is for another file. This vulnerability is fixed in 2026.05.1.

Weakness: CWE-918 (Server-Side Request Forgery), CWE-441 (Unintended Proxy or Intermediary)

- nocodb (npm): affected all versions up to 0.301.3; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
