Critical CVSS 9.1
CVE-2026-40005
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache IoTDB. An attacker can write arbitrary files anywhere the IoTDB process has write permissions with unsafe API. This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data and modify or destroy data.
- Weakness
- An attacker-supplied file path is not confined, letting them read or write outside the intended folder.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
