CVE-2026-59562: Apache IoTDB: Remote code execution and Unauthenticated path traversal in legacy pipe sendFile RPC

Noroxi assessment

Priority: Monitor (action score 39/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.56% (FIRST EPSS).
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: Apache Software Foundation Apache IoTDB 2.0.11.

Low priority for now. Upgrade to Apache Software Foundation Apache IoTDB 2.0.11 or later.
