VisualEditor: Broken OpenODBC browser plugin causes "application/iodbc" to be injected into the page
Closed, ResolvedPublic

Description

I had OpenODBC's iODBC plugin installed in Safari (latest release, always). After any edit, EMBED tags would be inserted at the top and bottom of the article. This did not occur with the source editor, or any other editable widget, like this one I'm typing in now.

Have you reported this upstream (i.e., to the author of the extension)? I don't this it's VE's fault, although I've seen similar stuff with another extension (FoxLingo):
[[m:en:Wikipedia:VisualEditor/Feedback/Archive_2013_07#Inserting_weird_script_tag_stuff]].

Actually, might be a more general bug, as these diffs have many similarities. I wonder if any other browser extensions do this.

Actually my post over on the Village Pump *appears* to have turned up several other examples of plugins having the same problem. Not much more I can add though...

Look for "Is this me or the editor?" (I can't get the section link to work)

Have you reported it to the author yet?

It is adding
<embed type="application/iodbc" width="0" height="0" />

embed is not one of the allowed html tags when $wgRawHtml is disabled, so the embed tag is escaped as a security measure. No malicious injection is possible via this bug.

You could write an AbuseFilter to prevent edits like this. This is not VE's fault. There is a problem with the extension. Has anyone notified the author of said extension?

"This is not VE's fault."

I am not at all certain of this. This problem ONLY occurs in VE. It does not occur in the source editor, or any other text editor across the whole wide web.

Something in VE is triggering this plugin to insert code. The plugin and the code it's inserting, is perfectly valid.

PiRSquared17 is right. This is not VE's fault. It only occurs in VE because of the way it sets up the editing area, which your plugin doesn't recognise as not to touch.

No and no.

This is now assigned to James Forrester. Will a special test for this specific text be added? What can be done to fix this bug? Seems more like an upstream issue IMHO.

No it isn't. Above line clearly says:

Assigned To: VE team bugs – take if you're interested!

Can't see a link to a bug filed upstream -> rm upstream keyword
