Critical ArangoDB Bugs Expose Entire Databases and Enable Remote Code Execution as Root

Two critical ArangoDB flaws (CVSS 9.8/9.9) allow unauthenticated API access and root-level code execution; fixed in 3.12.11.

Remedio researchers reported two critical ArangoDB flaws on August 23, 2026: an authentication bypass via URL-encoded underscores (%5f) in path parsing (GHSA-rrgq-978q-36mq, CVSS 9.8) and a task-execution flaw where a client-controlled isSystem flag lets JavaScript run in the internal context (GHSA-rvhw-4hpw-9vrx, CVSS 9.9). Chained, they allow unauthenticated database access, theft of root password hashes, and root-level code execution when arangod runs as root, such as in the official container image. Patches shipped August 31 in ArangoDB 3.12.11, with GitHub Security Advisories published September 6; CVE identifiers were pending at disclosure time.
