Description

On clean installs (empty databases) of TW 1.10 and 1.9.11 (also tested and confirmed on the clean 1.9.11 install on opensourcecms.com).
After users (perms tiki_p_create_blogs and tiki_p_blog_post enabled)create a blog they can proceed to post to any other user's blog. More precisely, on the post blog page, a user can select all blogs from the "Blog" field

Solution

it seems that the function user_has_perm_on_object in tikilib.php (called by the list_blogs_user_can_post function) returns true for all blogs. It seems to me that user_has_perm_on_object either confuses the permission levels of tiki_p_blog_post or it simply doesn't check whether the blog has been marked as private or not.

A quick work around (which completely bypasses user_has_perm_on_object so is probably poses a bunch of security risk):
in the file tikilib.php
in the function function list_blogs_user_can_post
Replace
if( $this->user_has_perm_on_object($user, $res'blogId', 'blog', 'tiki_p_blog_post',0)){

with
if( $user == $res'user' || $res'public' == 'y'){

Keywords

The following is a list of keywords that should serve as hubs for navigation within the Tiki development and should correspond to documentation keywords.

Each feature in Tiki has a wiki page which regroups all the bugs, requests for enhancements, etc. It is somewhat a form of wiki-based project management. You can also express your interest in a feature by adding it to your profile. You can also try out the Dynamic filter.
