What's New in Joomla 3.8.8
Security Issues Fixed
- Low Priority - Core - ACL violation in access levels (affecting Joomla 2.5.0 through 3.8.7) - Inadequate checks allowed users to modify the access levels of user groups with higher permissions.
- Low Priority - Core - Add phar files to the upload blacklist (affecting Joomla 2.5.0 through 3.8.7) - Depending on the server configuration, PHAR files might be handled as executable PHP scripts by the webserver.
- Moderate Priority - Core - Information Disclosure about unpublished tags (affecting Joomla 3.1.0 through 3.8.7) - Inadequate checks allowed users to see the names of tags that were either unpublished or published with restricted view permission.
- Low Priority - Core - Installer leaks plain text password to local user (affecting Joomla 3.0.0 through 3.8.7) - The web install application would autofill password fields after either a form validation error or navigating to a previous install step, and displays the plain text password for the administrator account at the confirmation screen.
- Moderate Priority - Core - XSS Vulnerabilities & additional hardening (affecting Joomla 3.0.0 through 3.8.7) - Inadequate input filtering leads to multiple XSS vulnerabilities. Additionally, the default filtering settings could potentially allow users of the default Administrator user group to perform a XSS attack.
- Low Priority - Core - Filter field in com_fields allows remote code execution (affecting Joomla 3.7.0 through 3.8.7) - Inadequate filtering allows users authorised to create custom fields to manipulate the filtering options and inject an unvalidated option.
- Low Priority - Core - Session deletion race condition (affecting Joomla 3.0.0 through 3.8.7) - A long running background process, such as remote checks for core or extension updates, could create a race condition where a session which was expected to be destroyed would be recreated.
- Low Priority - Core - Possible XSS attack in the redirect method (affecting Joomla 3.2.1 through 3.8.7) - Under specific circumstances (a redirect issued with a URI containing a username and password when the Location: header cannot be used), a lack of escaping the user-info component of the URI could result in a XSS vulnerability.
- Low Priority - Core - XSS vulnerability in the media manager (affecting Joomla 1.5.0 through 3.8.7) - Inadequate filtering of file and folder names lead to various XSS attack vectors in the media manager.
