keycloak: reset password token disclosure

It was found that keycloak before 3.4.2 final would permit misuse of a client-side /etc/hosts entry to spoof a URL in a password reset request. An attacker could use this flaw to craft a malicious password reset request and gain a valid reset token, leading to information disclosure or further attacks.

plone: Open URL redirect

By linking to a specific url in Plone 2.5-5.1rc1 with a parameter, an attacker could send you to his own website. On its own this is not so bad: the attacker could more easily link directly to his own website instead. But in combination with another attack, you could be sent to the Plone login form and login, then get redirected to the specific url, and then get a second redirect to the attacker website. (The specific url can be seen by inspecting the hotfix code, but we don't want to make it too easy for attackers by spelling it out here.)

plone: open redirect and XSS in login form

When you visit a page where you need to login, Plone 2.5-5.1rc1 sends you to the login form with a 'came_from' parameter set to the previous url. After you login, you get redirected to the page you tried to view before. An attacker might try to abuse this by letting you click on a specially crafted link. You would login, and get redirected to the site of the attacker, letting you think that you are still on the original Plone site. Or some javascript of the attacker could be executed. Most of these types of attacks are already blocked by Plone, using the `isURLInPortal` check to make sure we only redirect to a page on the same Plone site. But a few more ways of tricking Plone into accepting a malicious link were discovered, and fixed with this hotfix.

XMLBundle version 0.1.7 is vulnerable to XXE attacks which can result in denial of service attacks.

Wordpress plugin Furikake version 0.1.0 is vulnerable to an Open Redirect The furikake-redirect parameter on a page allows for a redirect to an attacker controlled page classes/Furigana.php: header('location:'.urldecode($_GET['furikake-redirect']));

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.

Nextcloud Server before 11.0.7 and 12.0.5 suffers from an Authorization Bypass Through User-Controlled Key vulnerability. A missing ownership check allowed logged-in users to change the scope of app passwords of other users. Note that the app passwords themselves where neither disclosed nor could the error be misused to identify as another user.
