Almost everything written by Edward Z. Yang (Ambush Commander). Lots of thanks
|
||||
to the DevNetwork Community for their help (see docs/ref-devnetwork.html for
|
||||
more details), Feyd especially (namely IPv6 and optimization). Thanks to RSnake
|
||||
for letting me package his fantastic XSS cheatsheet for a smoketest.

* HTML Purifier is an HTML filter that will take an arbitrary snippet of

|
||||
*
|

* -# Lexing (parsing into tokens) the document,
|
||||
* -# Executing various strategies on the tokens:
|
||||
* -# Removing all elements not in the whitelist,

* -# Making the tokens well-formed,
|
||||
* -# Fixing the nesting of the nodes, and
|

* -# Validating attributes of the nodes; and

* -# Generating HTML from the purified tokens.

// for example, 'MS Mincho', and it's considered
|
||||
// professional to use ASCII font names instead of
|
||||
// Unicode font names. Thanks Takeshi Terada for
|

// providing this information.
|

// The following characters, to my knowledge, have not been

|

// - Single quote. While theoretically you might find a
|
||||
// font name that has a single quote in its name (serving
|
||||
// as an apostrophe, e.g. Dave's Scribble), I haven't
|
||||
// been able to find any actual examples of this.
|
||||
// Internet Explorer's cssText translation (which I
|
||||
// believe is invoked by innerHTML) normalizes any
|
||||
// quoting to single quotes, and fails to escape single
|
||||
// quotes. (Note that this is not IE's behavior for all

// CSS properties, just some sort of special casing for
|
||||
// font-family). So a single quote *cannot* be used
|
||||
// safely in the font-family context if there will be an
|
||||
// innerHTML/cssText translation. Note that Firefox 3.x
|
||||
// does this too.
|
||||
// - Double quote. In IE, these get normalized to
|
||||
// single-quotes, no matter what the encoding. (Fun
|
||||
// fact, in IE8, the 'content' CSS property gained
|
||||
// support, where they special cased to preserve encoded
|
||||
// double quotes, but still translate unadorned double
|
||||
// quotes into single quotes.) So, because their
|
||||
// fixpoint behavior is identical to single quotes, they
|
||||
// cannot be allowed either. Firefox 3.x displays
|
||||
// single-quote style behavior.
|
||||
// - Backslashes are reduced by one (so \\ -> \) every
|
||||
// iteration, so they cannot be used safely. This shows
|
||||
// up in IE7, IE8 and FF3
|
||||
// - Semicolons, commas and backticks are handled properly.
|
||||
// - The rest of the ASCII punctuation is handled properly.
|
||||
// We haven't checked what browsers do to unadorned
|
||||
// versions, but this is not important as long as the
|
||||
// browser doesn't /remove/ surrounding quotes (as IE does
|
||||
// for HTML).
|
||||
//
|
||||
// With these results in hand, we conclude that there are
|
||||
// various levels of safety:
|
||||
// - Paranoid: alphanumeric, spaces and dashes(?)
|
||||
// - International: Paranoid + non-ASCII Unicode
|
||||
// - Edgy: Everything except quotes, backslashes
|
||||
// - NoJS: Standards compliance, e.g. sod IE. Note that
|
||||
// with some judicious character escaping (since certain
|
||||
// types of escaping doesn't work) this is theoretically
|
||||
// OK as long as innerHTML/cssText is not called.
|
||||
// We believe that international is a reasonable default
|
||||
// (that we will implement now), and once we do more
|
||||
// extensive research, we may feel comfortable with dropping
|
||||
// it down to edgy.
|
||||
|
||||
// Edgy: alphanumeric, spaces, dashes, underscores and Unicode. Use of
|
||||
// str(c)spn assumes that the string was already well formed

// Unicode (which of course it is).

*
|

* This is a bit confusing, because the DTDs and the W3C

|

*
|

* (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)
|

* But actually, the HTML4 spec then has this to say:
|

*
|
||||
* The TBODY start tag is always required except when the table
|

* contains only one table body and no table head or foot sections.
|
||||
* The TBODY end tag may always be safely omitted.
|

*
|

* So the DTD is kind of wrong. The validator is, unfortunately, kind

* of on crack.
|

|

* The definition changed again in XHTML1.1; and in my opinion, this

* formulation makes the most sense.

* caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))

|
||||
* If we encounter a thead, tfoot or tbody, we are placed in the former
