CVE-2026-34976: Dgraph Affected by Pre-Auth Database Overwrite + SSRF + File Read via restoreTenant Missing Authorization

Noroxi assessment

Priority: Plan (action score 41/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 2% (FIRST EPSS); higher than 81.3% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: dgraph-io dgraph 25.3.1.

Add it to your regular patch cycle. Upgrade to dgraph-io dgraph 25.3.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Dgraph is an open source distributed GraphQL database. Prior to 25.3.1, the restoreTenant admin mutation is missing from the authorization middleware config (admin.go), making it completely unauthenticated. Unlike the similar restore mutation which requires Guardian-of-Galaxy authentication, restoreTenant executes with zero middleware. This mutation accepts attacker-controlled backup source URLs (including file:// for local filesystem access), S3/MinIO credentials, encryption key file paths, and Vault credential file paths. An unauthenticated attacker can overwrite the entire database, read server-side files, and perform SSRF. This vulnerability is fixed in 25.3.1.
