01

What, why and how

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.0, an unvalidated redirect (open redirect) vulnerability exists in NocoDB’s login flow due to missing validation of the `continueAfterSignIn` parameter. During authentication, NocoDB processes a user-controlled redirect value and conditionally performs client-side navigation without enforcing any restrictions on the destination’s origin, domain or protocol. This allows attackers to redirect authenticated users to arbitrary external websites after login. This vulnerability enables phishing attacks by leveraging user trust in the legitimate NocoDB login flow. While it does not directly expose credentials or bypass authentication, it increases the likelihood of credential theft through social engineering. The issue does not allow arbitrary code execution or privilege escalation, but it undermines authentication integrity. Version 0.301.0 fixes the issue.

The issue does not allow arbitrary code execution or privilege escalation, but it undermines authentication integrity. Version 0.301.0 fixes the issue.

Why

The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

CWE-601: URL Redirection to Untrusted Site ('Open Redirect'). The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.

Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.

Official advisory ↗
JVN iPedia · Japanese · JVNDB-2026-002735nocodbにおけるオープンリダイレクトの脆弱性

NocoDBはスプレッドシートとしてデータベースを構築するためのソフトウェアです。バージョン0.301.0以前のNocoDBには、`continueAfterSignIn`パラメータの検証が欠如しているため、ログインフローに未検証のリダイレクト(オープンリダイレクト)脆弱性があります。認証中、NocoDBはユーザー制御のリダイレクト値を処理し、リダイレクト先のオリジン、ドメイン、またはプロトコルに対する制限を強制せずにクライアントサイドのナビゲーションを条件付きで実行します。これにより攻撃者は認証済みユーザーをログイン後に任意の外部ウェブサイトにリダイレクトできます。この脆弱性は正当なNocoDBログインフローへのユーザーの信頼を利用したフィッシング攻撃を可能にします。認証情報を直接露出させたり認証をバイパスしたりするものではありませんが、ソーシャルエンジニアリングによって認証情報窃取の可能性を高めます。この問題は任意コードの実行や権限昇格を許しませんが、認証の完全性を損ないます。バージョン0.301.0でこの問題は修正されました。
