Hi all, I'm facing an issue handling square brackets which seems to have been introduced sometime between 7.0.87 and 7.0.90.
I'm running from the docker hub image of tomcat, previously 'tomcat:7-jre8' but after that was updated to 7.0.90 I've pinned it back to 'tomcat:7.0.86-jre8' where I no longer seem to face the issue. I'm running a .war file of some open source software called DHIS2 (v2.27). When running 7.0.90, if I send requests of the following form: http://<host>/api/organisationUnits?fields=parent[id] I get the following error in the logs: Oct 29, 2018 5:04:01 PM org.apache.coyote.http11.AbstractHttp11Processor process INFO: Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 at org.apache.coyote.http11.InternalAprInputBuffer.parseRequestLine(InternalAprInputBuffer.java:240) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1049) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637) at org.apache.tomcat.util.net.AprEndpoint$SocketWithOptionsProcessor.run(AprEndpoint.java:2492) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:748) If I URL encode the square brackets the request seems to be fine.
