Yeah, some of these are false positives (especially migrateStewards). The others need further investigation. Most likely though they are i18n messages not being escaped.

AFAICT the CentralAuthuser and migrateStewards ones are false positives.

The SpecialCentralAutoLogin one is interesting, the code is:

			// And for good measure, add the edge login HTML images to the page.
			$script .= "\n" . Xml::encodeJsCall( "jQuery( 'body' ).append", [
				CentralAuthHooks::getEdgeLoginHTML()
			] );

\Xml::encodeJsCall() is hardcoded as the second argument being self::ESCAPES_HTML...and while that's true, it's also irrelevant to whether it is being double escaped or not. Should I suppress it? (if so, it should be refactored into a smaller function so we don't have to suppress the entire execute()).

\Xml::encodeJsCall() is hardcoded as the second argument being self::ESCAPES_HTML...and while that's true, it's also irrelevant to whether it is being double escaped or not. Should I suppress it? (if so, it should be refactored into a smaller function so we don't have to suppress the entire execute()).

Xml::encodeJsCall() escapes its $args as JSON, not HTML directly, and outputs a snippet of JavaScript code. I don't know if "escapes HTML" is all that accurate; complaining about double encoding when safed HTML is passed in certainly isn't.

In theory someone might do something like

$data = htmlspecialchars( '<b>not</b> HTML' );
$call = Xml::encodeJsCall( 'some.method', [ [ 'arg' => $data ] ] );
$elt = Html::element( 'span', [ 'onclick' => $call ], 'Click here!' );

producing

<span onclick="some.method({&quot;foo&quot;:&quot;\u0026lt;b\u0026gt;not\u0026lt;/b\u0026gt; HTML&quot;});">Click here!</span>

It's not double encoding that $data is passed to Xml::encodeJsCall() or that $call is passed to Html::element(), although it sounds like phan will complain about both if it thinks Xml::encodeJsCall() is dealing with HTML.

Xml::encodeJsCall() escapes its $args as JSON, not HTML directly, and outputs a snippet of JavaScript code. I don't know if "escapes HTML" is all that accurate;

There's a bunch of compromises in the plugin related to how JS escaping and HTML escaping work together, due to some limitations in the intelligence of the plugin.

In theory someone might do something like

$data = htmlspecialchars( '<b>not</b> HTML' );
$call = Xml::encodeJsCall( 'some.method', [ [ 'arg' => $data ] ] );
$elt = Html::element( 'span', [ 'onclick' => $call ], 'Click here!' );

Well, I would argue that's bad practise (escaping should happen when the data is used, in the example, it should happen in javascript). But you're right that it isn't double escaping. So I think I agree that it makes sense to have Xml::encodeJsCall to no longer care about double escaping.

Well, I would argue that's bad practise (escaping should happen when the data is used, in the example, it should happen in javascript).

Replace it with something like $data = Html::element( 'span', [ 'class' => $class ], $userInput ); if you want. Or $msg->parse() for that matter.

bug is fixed and taint-check running on this extension and there is no suppression involved here, it seems this is no longer needed
