SafeHTML 1.3.7

SafeHTML is an anti-XSS HTML parser, written in PHP.
This parser strips down all potentially dangerous content within HTML:
- opening tag without its closing tag
- closing tag without its opening tag
- any of these tags: “base”, “basefont”, “head”, “html”, “body”, “applet”, “object”, “iframe”, “frame”, “frameset”, “script”, “layer”, “ilayer”, “embed”, “bgsound”, “link”, “meta”, “style”, “title”, “blink”, “xml” etc.
- any of these attributes: on*, data*, dynsrc
- javascript:/vbscript:/about: etc. protocols
- expression/behavior etc. in styles
- any other active content
SafeHTML also tries to convert code to XHTML valid, but htmltidy is far better solution for this task.
Enhancements:
- This release adds a whitelist of "namespaced" attributes.
- It has more accurate UTF-7 decoding and minor improvements.
