Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Dgraph < 25.3.3 has a critical security flaw. The `cond` field in upsert mutations is **not escaped or parameterized**. ๐ **Consequences**: Unauthenticated attackers can **read the entire database**.โฆ
๐ก๏ธ **Root Cause**: **CWE-943** (Improper Neutralization of Special Elements in Data Query). The core flaw is the lack of proper sanitization/parameterization in the `cond` field during upsert operations.โฆ
๐ฆ **Affected**: **Dgraph** (Open-source distributed GraphQL DB). ๐ **Versions**: All versions **before 25.3.3**. Vendor: **dgraph-io**. Check your version immediately!
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: **Unauthenticated** access. ๐ต๏ธโโ๏ธ Can **read ALL data** in the database. High impact on Confidentiality (C:H) and Integrity (I:H). No login needed!
๐ซ **Public Exploit**: **None** listed in current data. `pocs` array is empty. However, the vulnerability is well-understood. Wild exploitation likely imminent if details leak. Stay vigilant!
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: 1. Verify Dgraph version. 2. Check for **upsert mutations** with `cond` fields. 3. Scan for unauthenticated GraphQL endpoints. 4. Review logs for suspicious query patterns. ๐ ๏ธ Use version checkers!
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: **YES**. Patch released in **v25.3.3**. ๐ Reference: GitHub Security Advisory GHSA-mrxx-39g5-ph77. Upgrade to v25.3.3 or later immediately! ๐
Q9What if no patch? (Workaround)
๐ **No Patch Workaround**: If you cannot upgrade: 1. **Restrict network access** to Dgraph ports. 2. **Disable** upsert mutations if not needed. 3. Implement **WAF rules** to block malicious GraphQL queries.โฆ
๐ฅ **Urgency**: **CRITICAL**. CVSS Score implies High Impact. Unauthenticated full data read is a nightmare scenario. ๐จ **Priority**: Patch immediately. Do not delay. Protect your data now!
