Tentatively guessing parsoid for tagging, but I'm really not sure who should be pinged here.

Change #1145913 had a related patch set uploaded (by Jforrester; author: Máté Szabó):
[mediawiki/core@wmf/1.44.0-wmf.28] TransformHandler: Return 400 for invalid titles
Change #1145913 abandoned by Jforrester:
[mediawiki/core@wmf/1.44.0-wmf.28] TransformHandler: Return 400 for invalid titles
Reason:
wmf.1 is everywhere.
In an attempt to verify and close this task, I ran into this. This is not from @mszabo's change but this response should not have been HTTP 403.
$ curl "https://en.wikipedia.org/w/rest.php/v1/page/||DBMS_PIPE.RECEIVE_MESSAGE(CHR(98)||CHR(98)||CHR(98)%2C15)||/html" {"errorKey":"rest-permission-denied-title","messageTranslations":{"en":"The user does not have rights to read title (||DBMS_PIPE.RECEIVE_MESSAGE(CHR(98)||CHR(98)||CHR(98),15)||)"},"httpCode":403,"httpReason":"Forbidden"}%
While this patch isn't yet deployed everywhere on wmf.1 (I see that the backport to wmf.1 is scheduled for a late backport window today), I can confirm the old failure on enwiki where this change isn't yet live.
$ curl -X POST -H "Content-Type: application/json" --data '{ "wikitext": "== Hello Jupiter ==" }' 'https://en.wikipedia.org/w/rest.php/v1/transform/wikitext/to/html/||DBMS_PIPE.RECEIVE_MESSAGE(CHR(98)||CHR(98)||CHR(98)%2C15)||' {"message":"Error: exception of type LogicException","httpCode":500,"httpReason":"Internal Server Error"}%
But, on mediawiki.org, where this change is live, I see this:
$ curl -X POST -H "Content-Type: application/json" --data '{ "wikitext": "== Hello Jupiter ==" }' 'https://www.mediawiki.org/w/rest.php/v1/transform/wikitext/to/html/||DBMS_PIPE.RECEIVE_MESSAGE(CHR(98)||CHR(98)||CHR(98)%2C15)||' {"errorKey":"rest-invalid-title","messageTranslations":{"en":"The specified title (pageName) does not refer to a wiki page."},"httpCode":400,"httpReason":"Bad Request"}%
So, once the backport is live, this task can be closed as resolved.
