lib/filelib.php in Moodle through 2.2.11, 2.3.x before 2.3.10, 2.4.x before 2.4.7, and 2.5.x before 2.5.3 does not send "Cache-Control: private" HTTP headers, which allows remote attackers to obtain sensitive information by requesting a file that had been previously retrieved by a caching proxy server.
Cross-site scripting (XSS) vulnerability in flashuploader.swf in the Uploader component in Yahoo! YUI 3.5.0 through 3.9.1, as used in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.1, and other products, allows remote attackers to inject arbitrary web script or HTML via a crafted string in a URL.
Cross-site scripting (XSS) vulnerability in uploader.swf in the Uploader component in Yahoo! YUI 3.2.0 through 3.9.1, as used in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.1, and other products, allows remote attackers to inject arbitrary web script or HTML via a crafted string in a URL.
mod/chat/guisockets/index.php in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 does not consider the mod/chat:chat capability before authorizing daemon-mode chat, which allows remote authenticated users to bypass intended access restrictions via an HTTP session to a chat server.
The moodle1 backup converter in backup/converter/moodle1/lib.php in Moodle 2.1.x before 2.1.10, 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 does not properly validate pathnames, which allows remote authenticated users to read arbitrary files by leveraging the backup-restoration feature.
webservice/lib.php in Moodle 2.1.x before 2.1.8, 2.2.x before 2.2.5, and 2.3.x before 2.3.2 does not properly restrict the use of web-service tokens, which allows remote authenticated users to run arbitrary external-service functions via a token intended for only one service.
lib/filelib.php in Moodle 2.1.x before 2.1.8, 2.2.x before 2.2.5, and 2.3.x before 2.3.2 does not properly check the publication state of blog files, which allows remote attackers to obtain sensitive information by reading a blog entry that references a non-public file.
mod/lesson/pagetypes/matching.php in Moodle through 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 allows remote authenticated users to obtain sensitive answer information by reading the HTML source code of a document.
The LTI (aka IMS-LTI) modform implementation in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 does not properly support the sendname, sendemailaddr, and acceptgrades settings, which allows remote attackers to obtain sensitive information in opportunistic circumstances by leveraging an environment in which there was an ineffective attempt to enable the more secure values.
rss/file.php in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 does not properly implement the use of RSS tokens for impersonation, which allows remote authenticated users to obtain sensitive block information by reading an RSS feed.
mod/feedback/lib.php in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 does not consider the mod/feedback:view capability before displaying recent feedback, which allows remote authenticated users to obtain sensitive information via a request for all course feedback that has occurred since a specified time.
Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 does not properly handle user/actionredir group messages, which allows remote authenticated users to discover e-mail addresses by visiting the messaging interface.
The web services implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly consider the maintenance-mode state and account attributes during login attempts, which allows remote authenticated users to bypass intended access restrictions by connecting to a webservice server.
Open redirect vulnerability in the Calendar set page in Moodle 2.1.x before 2.1.3 allows remote authenticated users to redirect users to arbitrary web sites and conduct phishing attacks via a redirection URL.
lib/moodlelib.php in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 does not properly handle certain zero values in the password policy, which makes it easier for remote attackers to obtain access by leveraging the possible existence of user accounts that have unchangeable blank passwords.
A number of flaws have been fixed in new upstream Moodle 2.1.3 [1], 2.0.6 [2], and 1.9.15 [3] releases. These do not have CVEs assigned (request pending), and since Fedora/EPEL will rebase to the latest versions of each branch, I'm summarizing them all here rather than creating a number of separate bugs.

backup/moodle2/restorestepslib.php in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not check for the moodle/course:changeidnumber privilege during handling of course ID numbers, which allows remote authenticated users to overwrite ID numbers via a restore action.
The command-line cron implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly interact with IP blocking, which might allow remote attackers to bypass intended IP address restrictions by leveraging a configuration in which IP blocking was disabled to restore cron functionality.
Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 displays web service tokens associated with (1) disabled services and (2) users who no longer have authorization, which allows remote authenticated users to have an unspecified impact by reading these tokens.
CRLF injection vulnerability in calendar/set.php in the Calendar subsystem in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.
The MNET authentication functionality in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote authenticated users to impersonate other user accounts by using the Login As feature in conjunction with a remote MNET single sign-on capability, as demonstrated by a Mahara site.
Cross-site scripting (XSS) vulnerability in the printobject function in lib/datalib.php in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3, when a developer debugging script is enabled, allows remote attackers to inject arbitrary web script or HTML via vectors involving object states.
classes/GoogleSpell.php in the PHP Spellchecker (aka Google Spellchecker) addon before 2.0.6.1 for TinyMCE, as used in Moodle 2.1.x before 2.1.10, 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 and other products, does not properly handle control characters, which allows remote attackers to trigger arbitrary outbound HTTP requests via a crafted string.
grade/edit/outcome/editform.php in Moodle 1.9.x through 1.9.19, 2.1.x before 2.1.10, 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 does not properly enforce the moodle/grade:manage capability requirement, which allows remote authenticated users to convert custom outcomes into standard site-wide outcomes by leveraging the teacher role and using the re-editing feature.
The Database activity module in Moodle 2.1.x before 2.1.9, 2.2.x before 2.2.6, and 2.3.x before 2.3.3 allows remote authenticated users to read activity entries of a different group's users via an advanced search.
The Database activity module in Moodle 2.1.x before 2.1.9, 2.2.x before 2.2.6, and 2.3.x before 2.3.3 allows remote attackers to bypass intended restrictions on reading other participants' entries via an advanced search.
The Dropbox Repository File Picker in Moodle 2.1.x before 2.1.9, 2.2.x before 2.2.6, and 2.3.x before 2.3.3 allows remote authenticated users to access the Dropbox of a different user by leveraging an unattended workstation after a logout.
The Portfolio plugin in Moodle 2.1.x before 2.1.9, 2.2.x before 2.2.6, and 2.3.x before 2.3.3 allows remote authenticated users to upload and execute files via a modified Portfolio API callback.
Moodle 1.9.x before 1.9.18, 2.0.x before 2.0.9, 2.1.x before 2.1.6, and 2.2.x before 2.2.3 allows remote authenticated users to bypass the moodle/calendar:manageownentries capability requirement and add a calendar entry via a New Entry action.
Moodle 2.1.x before 2.1.6 and 2.2.x before 2.2.3 allows remote authenticated users to bypass the moodle/site:readallmessages capability requirement and read arbitrary messages by using the "Recent conversations" feature with a modified parameter in a URL.
