From 6fbc0986fa2d49a1cb65b60eca71c25c84842a54 Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Tue, 6 Mar 2018 16:39:45 +0100 Subject: gui: Show messages as text not html Currently, error messages (such as InitError) are displayed as-is, which means Qt does auto detection on the format. This means that it's possible to inject HTML from the command line though e.g. specifying a wallet name with HTML in it. This isn't a direct security risk because fetching content from internet is disabled (and as far as I know we never report strings received from the network this way). However, it can be confusing. So explicitly force the format as text. --- src/qt/bitcoingui.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src') diff --git a/src/qt/bitcoingui.cpp b/src/qt/bitcoingui.cpp index 4e868b7c17..427eb95a84 100644 --- a/src/qt/bitcoingui.cpp +++ b/src/qt/bitcoingui.cpp @@ -923,6 +923,7 @@ void BitcoinGUI::message(const QString &title, const QString &message, unsigned showNormalIfMinimized(); QMessageBox mBox(static_cast(nMBoxIcon), strTitle, message, buttons, this); + mBox.setTextFormat(Qt::PlainText); int r = mBox.exec(); if (ret != nullptr) *ret = r == QMessageBox::Ok; -- cgit v1.2.3
