CVE Severity Published▾ Status Exploitation Description
CVE-2025-61788 Medium 2025-10-08 No exploit published No public exploit Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to Opencast 17.8 and 18.2, the paella would include and render some user inputs (metadata like title, description, etc.) unfiltered and unmodified. The vulnerability allows attackers to inject and malicious HTML and JavaScript in the player, which would then be executed in the browsers of users watching the prepared media. This can then be used to modify the site or to execute actions in the name of logged-in users. To inject malicious metadata, an attacker needs write access to the system. For example, the ability to upload media and modify metadata. This cannot be exploited by unauthenticated users. This issue is fixed in Opencast 17.8 and 18.2.
CVE-2025-54380 Medium 2025-07-26 No exploit published No public exploit Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to version 17.6, Opencast would incorrectly send the hashed global system account credentials (ie: org.opencastproject.security.digest.user and org.opencastproject.security.digest.pass) when attempting to fetch mediapackage elements included in a mediapackage XML file. A previous CVE prevented many cases where the credentials were inappropriately sent, but not all. Anyone with ingest permissions could cause Opencast to send its hashed global system account credentials to a url of their choosing. This issue is fixed in Opencast 17.6.
CVE-2018-16153 High 2023-12-12 No exploit published No public exploit An issue was discovered in Apereo Opencast 4.x through 10.x before 10.6. It sends system digest credentials during authentication attempts to arbitrary external services in some situations.
CVE-2022-41965 Medium 2022-11-28 No exploit published No public exploit Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to Opencast 12.5, Opencast's Paella authentication page could be used to redirect to an arbitrary URL for authenticated users. The vulnerability allows attackers to redirect users to sites outside of one's Opencast install, potentially facilitating phishing attacks or other security issues. This issue is fixed in Opencast 12.5 and newer.
CVE-2021-43807 High 2021-12-14 No exploit published No public exploit Opencast is an Open Source Lecture Capture & Video Management for Education. Opencast versions prior to 9.10 allow HTTP method spoofing, allowing to change the assumed HTTP method via URL parameter. This allows attackers to turn HTTP GET requests into PUT requests or an HTTP form to send DELETE requests. This bypasses restrictions otherwise put on these types of requests and aids in cross-site request forgery (CSRF) attacks, which would otherwise not be possible. The vulnerability allows attackers to craft links or forms which may change the server state. This issue is fixed in Opencast 9.10 and 10.0. You can mitigate the problem by setting the `SameSite=Strict` attribute for your cookies. If this is a viable option for you depends on your integrations. We strongly recommend updating in any case.
CVE-2020-5229 High 2020-01-30 No exploit published No public exploit Opencast before 8.1 stores passwords using the rather outdated and cryptographically insecure MD5 hash algorithm. Furthermore, the hashes are salted using the username instead of a random salt, causing hashes for users with the same username and password to collide which is problematic especially for popular users like the default `admin` user. This essentially means that for an attacker, it might be feasible to reconstruct a user's password given access to these hashes. Note that attackers needing access to the hashes means that they must gain access to the database in which these are stored first to be able to start cracking the passwords. The problem is addressed in Opencast 8.1 which now uses the modern and much stronger bcrypt password hashing algorithm for storing passwords. Note, that old hashes remain MD5 until the password is updated. For a list of users whose password hashes are stored using MD5, take a look at the `/user-utils/users/md5.json` REST endpoint.
