Discourse is an open source platform for community discussion. Tags that are normally private are showing in metadata. This affects any site running the `tests-passed` or `beta` branches >= 3.1.0.beta2. The issue is patched in the latest `beta` and `tests-passed` version of Discourse.

Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs.`lassoAppend' function accepts 3 arguments and internally invokes `push` function on the 1st argument specifying array consisting of 2nd and 3rd arguments as `push` call argument. The type of the 1st argument is supposed to be an array, but it's not enforced. This makes it possible to specify any object with a `push` function as the 1st argument, `push` function can be set to any function that can be access via `event.view` (no all such functions can be exploited due to invalid context or signature, but some can, e.g. `console.log`). The issue is that`lassoAppend` doesn't enforce proper types of its arguments. This issue opens various XSS vectors, but exact impact and severity depends on the environment (e.g. Core JS `setImmediate` polyfill basically allows `eval`-like functionality). This issue was patched in 5.23.0.

CleverStupidDog yf-exam v 1.8.0 is vulnerable to Deserialization which can lead to remote code execution (RCE).

### Summary Directus versions <=9.22.4 is vulnerable to Server-Side Request Forgery (SSRF) when importing a file from a remote web server (POST to `/files/import`). An attacker can bypass the security controls that were implemented to patch vulnerability [CVE-2022-23080](https://security.snyk.io/vuln/SNYK-JS-DIRECTUS-2934713) by performing a [DNS rebinding attack](https://en.wikipedia.org/wiki/DNS_rebinding) and view sensitive data from internal servers or perform a local port scan (eg. can access internal metadata API for AWS at `http://169.254.169.254` event if `169.254.169.254` is in the deny IP list). ### Details DNS rebinding attacks work by running a DNS name server that resolves two different IP addresses when a domain is resolved simultaneously. This type of attack can be exploited to bypass the IP address deny list validation that was added to [`/api/src/services/file.ts`](https://github.com/directus/directus/blob/main/api/src/services/files.ts) for the function `importOne` t...

On Barracuda CloudGen WAN Private Edge Gateway devices before 8 webui-sdwan-1089-8.3.1-174141891, an OS command injection vulnerability exists in /ajax/update_certificate - a crafted HTTP request allows an authenticated attacker to execute arbitrary commands. For example, a name field can contain :password and a password field can contain shell metacharacters.

The Watu Quiz plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘dn’, 'email', 'points', and 'date' parameters in versions up to, and including, 3.3.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Feb. 24 and March 3. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key

Barracuda CloudGen WAN provides a private edge appliance for hybrid deployments. An authenticated user in the administration interface for the private edge virtual appliance can inject arbitrary OS commands via the /ajax/update_certificate endpoint. Versions prior to v8.* hotfix 1089 are affected.

The China-aligned Mustang Panda actor has been observed using a hitherto unseen custom backdoor called MQsTTang as part of an ongoing social engineering campaign that commenced in January 2023. "Unlike most of the group's malware, MQsTTang doesn't seem to be based on existing families or publicly available projects," ESET researcher Alexandre Côté Cyr said in a new report. Attack chains

An issue was discovered in Gitpod versions prior to release-2022.11.2.16. There is a Cross-Site WebSocket Hijacking (CSWSH) vulnerability that allows attackers to make WebSocket connections to the Gitpod JSONRPC server using a victim’s credentials, because the Origin header is not restricted. This can lead to the extraction of data from workspaces, to a full takeover of the workspace.
