Note: disabling [Advanced Content Filter](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) is against [security best practices](http://docs.ckeditor.com/#!/guide/dev_best_practices-section-security), so the problem described above has not been considered a security issue as such.
+* Fixed the behavior of HTML parser when parsing `src`/`srcdoc` attributes of the `<iframe>` element in a CKEditor setup with ACF turned off and without the [Iframe Dialog](http://ckeditor.com/addon/iframe) plugin. The issue was originally reported as a security issue by [Sriramk21](https://twitter.com/sriramk21) from Pegasystems and was later downgraded by the security team into a normal issue due to the requirement of having ACF turned off.
