### Summary Server-side request forgery (SSRF) vulnerability in eKuiper allows an attacker with permissions to register external services or create rules to induce the eKuiper server to make requests to unintended network locations, such as internal services, loopback interfaces (localhost), or cloud metadata endpoints. ### Details Prior to v2.4.0, eKuiper external service registrations and HTTP invocations did not validate destination IP addresses. An attacker with access to the eKuiper management API could register an external service pointing to an internal address (such as `http://127.0.0.1:9081` or other internal network services) and trigger queries using service functions (e.g. `SELECT tsschemaless(...) FROM demo`). This allows probing internal networks, leaking sensitive information (such as internal endpoints/credentials), or interacting with internal APIs accessible to the eKuiper host. ### PoC 1. Create an external service with an address pointing to an internal network / localhost: ```json { "interfaces": { "tsschemaless": { "address": "http://127.0.0.1:9081", "protocol": "rest", "options": { "insecureSkipVerify": true, "header
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
