The LearnPress Export Import – WordPress extension for LearnPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'learnpress_import_form_server' parameter in all versions up to, and including, 4.0.4 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.

Certain EOL GeoVision devices have an OS Command Injection vulnerability. Unauthenticated remote attackers can exploit this vulnerability to inject and execute arbitrary system commands on the device. Moreover, this vulnerability has already been exploited by attackers, and we have received related reports.

Cross-Site Request Forgery (CSRF) vulnerability in GentleSource Appointmind allows Stored XSS.This issue affects Appointmind: from n/a through 4.0.0.

A heap-based buffer under-read in tsMuxer version nightly-2024-05-12-02-01-18 allows attackers to cause Denial of Service (DoS) via a crafted MOV video file.

The GitHub CLI version 2.6.1 and earlier are vulnerable to remote code execution through a malicious codespace SSH server when using `gh codespace ssh` or `gh codespace logs` commands. This has been patched in the cli v2.62.0.

Developers connect to remote codespaces through an SSH server running within the devcontainer, which is generally provided through the [default devcontainer image](https://docs.github.com/en/codespaces/setting-up-your-project-for-codespaces/adding-a-dev-container-configuration/introduction-to-dev-containers#using-the-default-dev-container-configuration). GitHub CLI [retrieves SSH connection details](https://github.com/cli/cli/blob/30066b0042d0c5928d959e288144300cb28196c9/internal/codespaces/rpc/invoker.go#L230-L244), such as remote username, which is used in [executing `ssh` commands](https://github.com/cli/cli/blob/e356c69a6f0125cfaac782c35acf77314f18908d/pkg/cmd/codespace/ssh.go#L263) for `gh codespace ssh` or `gh codespace logs` commands.

This exploit occurs when a malicious third-party devcontainer contains a modified SSH server that injects `ssh` arguments within the SSH connection details. `gh codespace ssh` and `gh codespace logs` commands could execute arbitrary code on the user's workstation if the remote username contains something like `-oProxyCommand="echo hacked" #`. The `-oProxyCommand` flag causes `ssh` to execute the provided command while `#` shell comment causes any other `ssh` arguments to be ignored.

In `2.62.0`, the remote username information is being validated before being used.

A heap-based buffer overflow in tsMuxer version nightly-2024-05-12-02-01-18 allows attackers to cause Denial of Service (DoS) and Code Execution via a crafted MOV video file.

A heap-based buffer overflow in tsMuxer version nightly-2024-03-14-01-51-12 allows attackers to cause Denial of Service (DoS), Information Disclosure and Code Execution via a crafted MKV video file.

A negative-size-param in tsMuxer version nightly-2024-04-05-01-53-02 allows attackers to cause Denial of Service (DoS) via a crafted TS video file.

A heap-based buffer overflow in tsMuxer version nightly-2024-03-14-01-51-12 allows attackers to cause Denial of Service (DoS) and Code Execution via a crafted MOV video file.

A heap-based buffer overflow in tsMuxer version nightly-2024-05-10-02-00-45 allows attackers to cause Denial of Service (DoS) via a crafted MKV video file.
