- Files within the storage/ path could be accessed via path traversal
references in content, accessed upon HTML export.
- This addresses this via two layers:
- Scoped local flysystem filesystems down to the specific image &
file folders since flysystem has built-in checking against the
escaping of the root folder.
- Added path normalization before enforcement of uploads/{images,file}
prefix to prevent traversal at a path level.

For #2700 and #2631.
- Reduced options to single new configuration paramter instead of two.
- Moved more logic into UserAvatars class.
- Updated LDAP avatar import to also run on login when no image is
currently set.
- Added thumbnail fetching to search requests.
- Added testing to cover.

To ensure thhat the visibility is still set on local storage options
since the previous recent changes could cause problems where in
scenarios where the server user could not read images uploaded by the
php process user.
Closes#2758
The content of pages made non-viewable to a user via permissions, within a visible parent, could be seen via the plaintext export option. Before v0.30.6 this would have applied only to scenarios where all pages within the chapter were made non-visible. In v0.30.6 this would make all pages within the chapter visible.
As per #2414
This filters out potentially malicious javascript: or data: uri's coming
through to be attached to attachments.
Added tests to cover.
Thanks to Yassine ABOUKIR (@yassineaboukir on twitter) for reporting this
vulnerability.
Cannot get working in chrome reliably due to conflicting handling of
events and drag+drop API. Getting attachment drop working breaks other
parts of TinyMCE.
Implementing current work as should still work for MD editor and within
FireFox.
Related to #1460
Currently fighting between sortable and tinymce mechanisms which prevent
this working due to the different events stopping the drop event while
needing the dragover for cursor placement.
- Created new dropzone component.
- Added standard component event system using custom DOM events.
- Added tabs component.
- Added ajax-delete-row component.
- Instead of user name.
- Due to issues with advanced charts like emoji zero-width-joiners.
- Could also have security concerns on untrusted instances with certain
webserver config due to double extension possibilities.
Closes#1993
Thumbnail generation would sometimes create a file larger than the
original, if the original was already well optimized, therefore making
the thumbnail counter-productive. This change compares the sizes of the
original and the generated thumbnail, and uses the smaller of the two if
the thumbnail does not change the aspect ratio of the image.
Fixes#1751
