Sanitize History

Version 2.0.3 (2011-07-01)

  • Loosened the Nokogiri dependency to allow Nokogiri 1.5.x.

Version 2.0.2 (2011-05-21)

  • Fixed a bug in which a protocol like "java\script:" would be translated to "java%5Cscript:" and allowed through the filter when relative URLs were enabled. This didn't actually allow malicious code to run, but it is undesired behavior.

Version 2.0.1 (2011-03-16)

  • Updated the protocol regex to anchor at the beginning of the string rather than the beginning of a line. [Eaden McKee]

Version 2.0.0 (2011-01-15)

  • The environment data passed into transformers and the return values expected from transformers have changed. Old transformers will need to be updated. See the README for details.
  • Transformers now receive nodes of all types, not just element nodes.
  • Sanitize's own core filtering logic is now implemented as a set of always-on transformers.
  • The default value for the :output config is now :html. Previously it was :xhtml.
  • Added a :whitespace_elements config, which specifies elements (such as <br> and <p>) that should be replaced with whitespace when removed in order to preserve readability. See the README for the default list of elements that will be replaced with whitespace when removed.
  • Added a :transformers_breadth config, which may be used to specify transformers that should traverse nodes in a breadth-first mode rather than the default depth-first mode.
  • Added the abbr, dfn, kbd, mark, s, samp, time, and var elements to the whitelists for the basic and relaxed configs.
  • Added the bdo, del, figcaption, figure, hgroup, ins, rp, rt, ruby, and wbr elements to the whitelist for the relaxed config.
  • The dir, lang, and title attributes are now whitelisted for all elements in the relaxed config.
  • Bumped minimum Nokogiri version to 1.4.4 to avoid a bug in 1.4.2+ (issue #315) that caused </body></html> to be appended to the CDATA inside unterminated script and style elements.

Version 1.2.1 (2010-04-20)

  • Added a :remove_contents config setting. If set to true, Sanitize will remove the contents of all non-whitelisted elements in addition to the elements themselves. If set to an array of element names, Sanitize will remove the contents of only those elements (when filtered), and leave the contents of other filtered elements. [Thanks to Rafael Souza for the array option]
  • Added an :output_encoding config setting to allow the character encoding for HTML output to be specified. The default is utf-8.
  • The environment hash passed into transformers now includes a :node_name item containing the lowercase name of the current HTML node (e.g. "div").
  • Returning anything other than a Hash or nil from a transformer will now raise a meaningful Sanitize::Error exception rather than an unintended NameError.

Version 1.2.0 (2010-01-17)

  • Requires Nokogiri ~> 1.4.1.
  • Added support for transformers, which allow you to filter and alter nodes using your own custom logic, on top of (or instead of) Sanitize's core filter. See the README for details and examples.
  • Added Sanitize.clean_node!, which sanitizes a Nokogiri::XML::Node and all its children.
  • Added elements <h1> through <h6> to the Relaxed whitelist. [Suggested by David Reese]

Version 1.1.0 (2009-10-11)

  • Migrated from Hpricot to Nokogiri. Requires libxml2 >= 2.7.2 [Adam Hooper]
  • Added an :output config setting to allow the output format to be specified. Supported formats are :xhtml (the default) and :html (which outputs HTML4).
  • Changed protocol regex to ensure Sanitize doesn't kill URLs with colons in path segments. [Peter Cooper]

Version 1.0.8 (2009-04-23)

  • Added a workaround for an Hpricot bug that prevents attribute names from being downcased in recent versions of Hpricot. This was exploitable to prevent non-whitelisted protocols from being cleaned. [Reported by Ben Wanicur]

Version 1.0.7 (2009-04-11)

  • Requires Hpricot 0.8.1+, which is finally compatible with Ruby 1.9.1.
  • Fixed a bug that caused named character entities containing digits (like &sup2;) to be escaped when they shouldn't have been. [Reported by Sebastian Steinmetz]

Version 1.0.6 (2009-02-23)

  • Removed htmlentities gem dependency.
  • Existing well-formed character entity references in the input string are now preserved rather than being decoded and re-encoded.
  • The ' character is now encoded as &#39; instead of &apos; to prevent problems in IE6.
  • You can now specify the symbol :all in place of an element name in the attributes config hash to allow certain attributes on all elements. [Thanks to Mutwin Kraus]

Version 1.0.5 (2009-02-05)

  • Fixed a bug introduced in version 1.0.3 that prevented non-whitelisted protocols from being cleaned when relative URLs were allowed. [Reported by Dev Purkayastha]
  • Fixed "undefined method `parent='" exceptions caused by parser changes in edge Hpricot.

Version 1.0.4 (2009-01-16)

  • Fixed a bug that made it possible to sneak a non-whitelisted element through by repeating it several times in a row. All versions of Sanitize prior to 1.0.4 are vulnerable. [Reported by Cristobal]

Version 1.0.3 (2009-01-15)

  • Fixed a bug whereby incomplete Unicode or hex entities could be used to prevent non-whitelisted protocols from being cleaned. Since IE6 and Opera still decode the incomplete entities, users of those browsers may be vulnerable to malicious script injection on websites using versions of Sanitize prior to 1.0.3.

Version 1.0.2 (2009-01-04)

  • Fixed a bug that caused an exception to be thrown when parsing a valueless attribute that's expected to contain a URL.

Version 1.0.1 (2009-01-01)

  • You can now specify :relative in a protocol config array to allow attributes containing relative URLs with no protocol. The Basic and Relaxed configs have been updated to allow relative URLs.
  • Added a workaround for an Hpricot bug that causes HTML entities for non-ASCII characters to be replaced by question marks, and all other entities to be destructively decoded.

Version 1.0.0 (2008-12-25)

  • First release.
