Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: ZITADEL suffers from **Insecure Direct Object References (IDOR)**.…
🛡️ **Root Cause**: **CWE-639** (Insecure Direct Object Reference). The flaw lies in how the application validates object access, allowing users to manipulate IDs to access other users' data.
Q3Who is affected? (Versions/Components)
👥 **Affected**: **ZITADEL** (Open Source IAM). Specifically, versions prior to the fix released in March 2025. It impacts the core authentication and authorization logic.
Q4What can hackers do? (Privileges/Data)
💀 **Attacker Capabilities**: With valid credentials, hackers can **read/modify** other users' data (High Impact on Confidentiality/Integrity). They can escalate privileges or access sensitive tenant information.
Q5Is exploitation threshold high? (Auth/Config)
⚖️ **Exploitation Threshold**: **Medium**. CVSS indicates **PR:H** (Privileges Required). You need a valid account to exploit this, but **AC:L** (Low Complexity) makes it easy to execute once logged in.
Q6Is there a public Exp? (PoC/Wild Exploitation)
🔍 **Public Exploit**: **No**. The `pocs` field is empty. No public Proof-of-Concept or wild exploitation scripts are currently available. It relies on manual ID manipulation.
Q7How to self-check? (Features/Scanning)
🔎 **Self-Check**: Review API calls for **IDOR patterns**. Check if user IDs are predictable or if the backend validates ownership of the referenced object against the authenticated user's session.
Q8Is it fixed officially? (Patch/Mitigation)
✅ **Fixed**: **Yes**. A patch was published on **2025-03-04**. Refer to the GitHub Security Advisory (GHSA-f3gh-529w-v32x) and commit `d9d8339` for the official fix.
Q9What if no patch? (Workaround)
🚧 **No Patch Workaround**: Implement strict **server-side authorization checks**. Ensure every API request validates that the requester owns the requested resource ID. Use indirect references if possible.
Q10Is it urgent? (Priority Suggestion)
🔥 **Urgency**: **High**. CVSS Score is **High** (C:H, I:H). Even though auth is required, the impact on data integrity and confidentiality is severe. **Patch immediately** upon upgrading.
