Swift ASN.1 can be caused to crash when parsing certain BER/DER constructions. This crash is caused by a confusion in the ASN.1 library itself which assumes that certain objects can only be provided in either constructed or primitive forms, and will trigger a `preconditionFailure` if that constraint isn't met. Importantly, these constraints are actually required to be true in DER, but that correctness wasn't enforced on the early node parser side so it was incorrect to rely on it later on in decoding, which is what the library did. These crashes can be triggered when parsing any DER/BER format object. There is no memory-safety issue here: the crash is a graceful one from the Swift runtime. The impact of this is that it can be used as a denial-of-service vector when parsing BER/DER data from unknown sources, e.g. when parsing TLS certificates. Many thanks to @baarde for reporting this issue and providing the fix.

### Impact NOTE: The [Realtime WYSIWYG Editor](https://extensions.xwiki.org/xwiki/bin/view/Extension/Realtime%20WYSIWYG%20Editor/) extension was **experimental**, and thus **not recommended**, in the versions affected by this vulnerability. It has become enabled by default, and thus recommended, starting with XWiki 16.9.0. A user with only **edit right** can join a realtime editing session where others, that where already there or that may join later, have **script** or **programming** access rights. This user can then insert **script rendering macros** that are executed for those users in the realtime session that have script or programming rights. The inserted scripts can be used to gain more access rights. Here's an example that works with XWiki 15.10.9+ and 16.2.0+: * the attacker starts editing a wiki page in realtime (for which they have edit right) * another user, with script or programming access right joins the editing session (e.g. by clicking on a link / URL provided by ...

## Vulnerability A vulnerability has been identified in Rasa Pro and Rasa Open Source that enables an attacker who has the ability to load a maliciously crafted model remotely into a Rasa instance to achieve Remote Code Execution. The prerequisites for this are: - The HTTP API must be enabled on the Rasa instance eg with `--enable-api`. This is not the default configuration. - For unauthenticated RCE to be exploitable, the user must not have configured any authentication or other security controls recommended in our documentation. - For authenticated RCE, the attacker must posses a valid authentication token or JWT to interact with the Rasa API. ## Fix We encourage you to upgrade to a version of Rasa that includes a fix. These are: - Rasa Pro 3.8.18, 3.9.16, 3.10.12 - Rasa Open Source 3.6.21 Once you have upgraded your Rasa Pro or Open Source installation, you will need to retrain your model using the fixed version of Rasa Pro or Open Source. If you have a custom component that inh...

### Problem A vulnerability has been identified in the backend user interface functionality involving deep links. Specifically, this functionality is susceptible to Cross-Site Request Forgery (CSRF). Additionally, state-changing actions in downstream components incorrectly accepted submissions via HTTP GET and did not enforce the appropriate HTTP method. Successful exploitation of this vulnerability requires the victim to have an active session on the backend user interface and to be deceived into interacting with a malicious URL targeting the backend, which can occur under the following conditions: * the user opens a malicious link, such as one sent via email. * the user visits a compromised or manipulated website while the following settings are misconfigured: + `security.backend.enforceReferrer` feature is disabled, + `BE/cookieSameSite` configuration is set to `lax` or `none` The vulnerability in the affected downstream component “DB Check Module” allows attackers to manipul...
