*Intro*

A new version of DOMPurify was released today: DOMPurify 2.0.7

*Background*

Following the maintenance release of DOMPurify 2.0.6, an array of mXSS
variations, spotted by Masato Kinugawa in an internal code audit, was
addressed and fixed. This time, the attacks made use of mutations caused
by content removal from non-HTML tags inside HTML context.

*Fix*

DOMPurify is now more aware of this and comparable browser issues
and changes the sanitization behavior to be more secure. The fix has
been reviewed by the original finder as well.

*Packages*

Updated packages are available here:
