Two critical ArangoDB vulnerabilities, GHSA-rrgq-978q-36mq and GHSA-rvhw-4hpw-9vrx, affect releases through 3.12.10.1. The first abuses inconsistent raw-versus-decoded URL handling to reach protected API endpoints without credentials when the default system-only authentication configuration is used. The second enables a database user with write permissions to manipulate the isSystem field and schedule JavaScript tasks that execute in a privileged internal context.
Attackers can chain the flaws to gain administrative database access and execute code on the underlying host, potentially as root. Risk is especially acute for the official container image, where arangod runs as root. ArangoDB fixed the issues in version 3.12.11; organizations should upgrade promptly, restrict database exposure, rotate potentially exposed credentials and secrets, and investigate anomalous API requests and JavaScript task creation.

3 events from the most recent confirmed update back to the earliest known activity.
Advisories for GHSA-rrgq-978q-36mq and GHSA-rvhw-4hpw-9vrx were published, documenting potential unauthenticated access to protected APIs and privileged task execution. CVE identifiers were still pending at the time of disclosure.
ArangoDB released version 3.12.11 to fix both critical vulnerabilities. The fixes addressed the URL-decoding authentication bypass and insufficient authorization of privileged background tasks.
Remedio reported two HTTP-interface vulnerabilities in ArangoDB: an authentication bypass (GHSA-rrgq-978q-36mq) and privileged JavaScript task execution issue (GHSA-rvhw-4hpw-9vrx). The flaws affect releases through version 3.12.10.1 and can be chained for administrative access and privileged host actions.
