The Directus process can be aborted by having an authorized user update the `filename_disk` value to a folder and accessing that file through the `/assets` endpoint. The vulnerability is patched and released in v9.15.0. You can prevent this problem by making sure no (untrusted) non-admin users have permissions to update the `filename_disk` field on `directus_files`. ### For more information If you have any questions or comments about this advisory: * Open a Discussion in [directus/directus](https://github.com/directus/directus/discussions) * Email us at [security@directus.io](mailto:security@directus.io) ### Credits This vulnerability was first discovered and reported by Witold Gorecki.

### Impact If a user has Network Policies with namespace selectors selecting labels of namespaces, or (clusterwide) Cilium Network Policies matching on namespace labels, then it is possible for an attacker with Kubernetes pod deploy rights (either directly or indirectly via higher-level APIs such as Deployment, Daemonset etc) to craft additional pod labels such that the pod is selected by another policy that exists rather than the expected policy. ### Patches The problem has been fixed and is available on versions >=1.10.14, >=1.11.8, >=1.12.1 ### Workarounds There are no workarounds available. ### Acknowledgements The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to Sander Mathijssen for not only highlighting the issue but also proposing a resolution. ### For more information If you have any questions or comments about this advisory, please reach out on [Slack](https://docs.cilium.io/en/latest/community/community...

In iana-time-zone v0.1.43 a use-after-free bug in the MacOS / iOS implementation was introduced. The copied system time zone was released before its name was copied. If the system time zone was changed between the call of `CFRelease` and `str::to_owned()`, random memory would be copied.

### Impact The power level parsing within gomatrixserverlib was failing to parse the `"events_default"` key of the `m.room.power_levels` event, defaulting the event default power level to zero in all cases. In rooms where the `"events_default"` power level had been changed, this could result in events either being incorrectly authorised or rejected by Dendrite servers. ### Patches gomatrixserverlib contains a fix as of commit `723fd49` and Dendrite 0.9.3 has been updated accordingly. ### Workarounds Matrix rooms where the `"events_default"` power level has not been changed from the default of zero are not vulnerable. ### For more information If you have any questions or comments about this advisory, e-mail us at [security@matrix.org](mailto:security@matrix.org).

Affected versions of this crate passes an uninitialized buffer to a user-provided `Read` implementation. Arbitrary `Read` implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior. Note: there is only UB in the case where a user provides a struct whose `Read` implementation inspects the buffer passed to `read_exact` before writing to it. This is an unidiomatic (albeit possible) `Read` implementation. See https://github.com/MaterializeInc/materialize/issues/8669 for details.

### Introduction Cross-site scripting (XSS) is a type of vulnerability that allows to execute any kind of JavaScript code inside the Panel session of the same or other users. In the Panel, a harmful script can for example trigger requests to Kirby's API with the permissions of the victim. Such vulnerabilities are critical if you might have potential attackers in your group of authenticated Panel users. They can escalate their privileges if they get access to the Panel session of an admin user. Depending on your site, other JavaScript-powered attacks are possible. ### Impact The multiselect field allows to select tags from an autocompleted list. Unfortunately, the Panel in Kirby 3.5 used HTML rendering for the raw option value. This allowed **attackers with influence on the options source** (e.g. content of sibling pages or an API endpoint) to inject HTML code. If a page in the Panel that uses the manipulated multiselect options was visited by a victim and the victim opened the aut...

A flaw was found in Keycloak. This vulnerability allows anyone to register a new security device or key when there is not a device already registered for any user by using the WebAuthn password-less login flow.

ClassLoaderTheme and ClasspathThemeResourceProviderFactory allows reading any file available as a resource to the classloader. By sending requests for theme resources with a relative path from an external HTTP client, the client will receive the content of random files if available.
