login/token.php in Moodle through 2.3.11, 2.4.x before 2.4.10, 2.5.x before 2.5.6, and 2.6.x before 2.6.3 creates a MoodleMobile web-service token with an infinite lifetime, which makes it easier for remote attackers to hijack sessions via a brute-force attack.
Multiple cross-site request forgery (CSRF) vulnerabilities in mod/assign/locallib.php in the Assignment subsystem in Moodle through 2.3.11, 2.4.x before 2.4.10, 2.5.x before 2.5.6, and 2.6.x before 2.6.3 allow remote attackers to hijack the authentication of teachers for quick-grading requests.

repository/alfresco/lib.php in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 places a session key in a URL, which allows remote attackers to bypass intended Alfresco Repository file restrictions by impersonating a file's owner.
course/loginas.php in Moodle through 2.2.11, 2.3.x before 2.3.11, 2.4.x before 2.4.8, 2.5.x before 2.5.4, and 2.6.x before 2.6.1 does not enforce the moodle/site:accessallgroups capability requirement for outside-group users in a SEPARATEGROUPS configuration, which allows remote authenticated users to perform "login as" actions via a direct request.
The My Home implementation in the blockhtmlpluginfile function in blocks/html/lib.php in Moodle through 2.3.11, 2.4.x before 2.4.10, 2.5.x before 2.5.6, and 2.6.x before 2.6.3 does not properly restrict file access, which allows remote attackers to obtain sensitive information by visiting an HTML block.
CRLF injection vulnerability in calendar/set.php in the Calendar component in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, 2.1.x before 2.1.3, and 2.2 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via vectors involving the url variable.
The wiki subsystem in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 does not properly restrict (1) view and (2) edit access, which allows remote authenticated users to perform wiki operations by leveraging the student role and using the Recent Activity block to reach the individual wiki of an arbitrary student.
The time-validation implementation in (1) mod/feedback/complete.php and (2) mod/feedback/completeguest.php in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 allows remote authenticated users to bypass intended restrictions on starting a Feedback activity by choosing an unavailable time.
mod/chat/chatajax.php in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 does not properly check for the mod/chat:chat capability during chat sessions, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by remaining in a chat session after an intra-session capability removal by an administrator.
Cross-Site Scripting in 3rd party library Flowplayer
Cross-site scripting (XSS) vulnerability in the URL downloader repository in repository/url/lib.php in Moodle through 2.3.11, 2.4.x before 2.4.10, 2.5.x before 2.5.6, and 2.6.x before 2.6.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
Algorithmic complexity vulnerability in Moodle 1.9.x before 1.9.19, 2.0.x before 2.0.10, 2.1.x before 2.1.7, and 2.2.x before 2.2.4 allows remote authenticated users to cause a denial of service (CPU consumption) by using the advanced-search feature on a database activity that has many records.
lib/modinfolib.php in Moodle 2.0.x before 2.0.10, 2.1.x before 2.1.7, 2.2.x before 2.2.4, and 2.3.x before 2.3.1 does not check for a group-membership requirement when determining whether an activity is unavailable or hidden, which allows remote authenticated users to bypass intended access restrictions by selecting an activity that is configured for a group of other users.
badges/mybadges.php in Moodle 2.5.x before 2.5.5 and 2.6.x before 2.6.2 does not properly track the user to whom a badge was issued, which allows remote authenticated users to modify the visibility of an arbitrary badge via unspecified vectors.
The identity-reporting implementations in mod/forum/renderer.php and mod/quiz/overrideform.php in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 do not properly restrict the display of e-mail addresses, which allows remote authenticated users to obtain sensitive information by using the (1) Forum or (2) Quiz module.
The blind-marking implementation in Moodle through 2.3.11, 2.4.x before 2.4.10, 2.5.x before 2.5.6, and 2.6.x before 2.6.3 allows remote authenticated users to de-anonymize student identities by (1) using a screen reader or (2) reading the HTML source.
Cross-site scripting (XSS) vulnerability in cohort/editform.php in Moodle 2.0.x before 2.0.10, 2.1.x before 2.1.7, 2.2.x before 2.2.4, and 2.3.x before 2.3.1 allows remote authenticated administrators to inject arbitrary web script or HTML via the idnumber field. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-2365.
Cross-site scripting (XSS) vulnerability in the quizquestiontostring function in mod/quiz/editlib.php in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 allows remote authenticated users to inject arbitrary web script or HTML via a quiz question.
