Generate an Elasticsearch API key after container start - #12071
Conversation
Elasticsearch 8+ with security now exposes getApiKey() so tests can authenticate without the elastic password. Co-authored-by: Cursor <cursoragent@cursor.com>
📝 WalkthroughWalkthroughThe Elasticsearch container now generates an API key after startup for secured Elasticsearch 8 and later instances. ChangesElasticsearch API key support
Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to API-key generation is not ready to merge because a crafted certificate path can execute commands inside the Elasticsearch container during startup. Pass the path as a separate process argument and add regression coverage. Sequence Diagram(s)sequenceDiagram

@pioorg Another one for you. I think it's better to get an API Key from the ES container and make people use api keys instead of static username and passwords. |

- Line 288: Update the curl execution flow in ElasticsearchContainer to avoid
interpolating certPath into a shell command: invoke curl without /bin/sh -c and
pass certPath as a separate argument, preserving the insecure -k fallback when
no certificate path is configured. Add a regression test covering a quoted
certificate path and verifying that a harmless marker-file payload is not
executed.

Do not interpolate certPath into the shell command.
withCertPath() accepts caller configuration without shell escaping. The value is inserted into a single-quoted fragment and executed through /bin/sh -c. A value containing ' ; <command> # can execute a command inside the Elasticsearch container.
Invoke curl without /bin/sh -c, and pass certPath as a separate argument. Add a regression test with a quoted path and a harmless marker-file payload.
