In Mahara before 20.04.5, 20.10.3, 21.04.2, and 21.10.0, the account associated with a web services token is vulnerable to being exploited and logged into, resulting in information disclosure (at a minimum) and often escalation of privileges.
Cross-site Scripting (XSS) in Mahara before 1.5.9 and 1.6.x before 1.6.4 allows remote attackers to inject arbitrary web script or HTML via the TinyMCE editor.
An issue was discovered in Mahara before 18.10.0. It mishandled user requests that could discontinue a user's ability to maintain their own account (changing username, changing primary email address, deleting account). The correct behavior was to either prompt them for their password and/or send a warning to their primary email address.
Mahara before 1.5.12, 1.6.x before 1.6.7, and 1.7.x before 1.7.3 does not properly restrict access to artefacts, which allows remote authenticated users to read arbitrary artefacts via the (1) artefact id in an upload action when creating a journal or (2) instconf_artefactid_selected[ID] parameter in an upload action when editing a block.
Cross-site scripting (XSS) vulnerability in Mahara before 1.5.12, 1.6.x before 1.6.7, and 1.7.x before 1.7.3 allows remote attackers to inject arbitrary web script or HTML via the Host header to lib/web.php.
Mahara before 1.5.12, 1.6.x before 1.6.7, and 1.7.x before 1.7.3 does not properly prevent access to blocks, which allows remote authenticated users to modify arbitrary blocks via the bock id in an edit request.
Mahara before 1.5.13, 1.6.x before 1.6.8, and 1.7.x before 1.7.4 does not properly restrict access to folders, which allows remote authenticated users to read arbitrary folders (1) by leveraging an active folder tab loaded before permissions were removed or (2) via the folder parameter to artefact/file/groupfiles.php.
The default configuration of the auth/saml plugin in Mahara before 1.4.2 sets the "Match username attribute to Remote username" option to false, which allows remote SAML IdP servers to spoof users of other SAML IdP servers by using the same internal username.
The get_dataroot_image_path function in lib/file.php in Mahara before 1.4.1 does not properly validate uploaded image files, which allows remote attackers to cause a denial of service (memory consumption) via a (1) large or (2) invalid image.
Cross-site request forgery (CSRF) vulnerability in Mahara before 1.4.1 allows remote attackers to hijack the authentication of administrators for requests that add a user to an institution.
