Versions of the package http-proxy-middleware before 2.0.7, from 3.0.0 and before 3.0.3 are vulnerable to Denial of Service (DoS) due to an UnhandledPromiseRejection error thrown by micromatch. An attacker could kill the Node.js process and crash the server by making requests to certain paths.

This security update resolves a vulnerability in the OPC UA .NET Standard Stack that allows an unauthorized attacker to trigger a gradual degradation in performance.

### Impact The CVE is for a software vulnerability. Network admins who have deployed tacquito (or versions of tacquito) in their production environments and use tacquito to perform command authorization for network devices should be impacted. Tacquito code prior to commit 07b49d1358e6ec0b5aa482fcd284f509191119e2 was performing regex matches on authorized commands and arguments in a more permissive than intended manner. Configured allowed commands/arguments were intended to require a match on the entire string, but instead only enforced a match on a sub-string. This behaviour could potentially allowed unauthorized commands to be executed. ### Patches The problem has been patched, and users should update to the latest github repo commit to get the patch. ### Workarounds Users should be able to add boundary conditions anchors '^' and '$' to their command configs to remediate the vulnerability without the upgrade

The fix for CVE-2022-22968 made disallowedFields patterns in DataBinder case insensitive. However, String.toLowerCase() has some Locale dependent exceptions that could potentially result in fields not protected as expected.

The SQL Expressions experimental feature of Grafana allows for the evaluation of `duckdb` queries containing user input. These queries are insufficiently sanitized before being passed to `duckdb`, leading to a command injection and local file inclusion vulnerability. Any user with the VIEWER or higher permission is capable of executing this attack. The `duckdb` binary must be present in Grafana's $PATH for this attack to function; by default, this binary is not installed in Grafana distributions.

### Impact When this library is used to deserialize messagepack data from an untrusted source, there is a risk of a denial of service attack by an attacker that sends data contrived to produce hash collisions, leading to large CPU consumption disproportionate to the size of the data being deserialized. This is similar to [a prior advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf), which provided an inadequate fix for the hash collision part of the vulnerability. ### Patches The following steps are required to mitigate this risk. 1. Upgrade to a version of the library where a fix is available. 1. Review the steps in [this previous advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf) to ensure you have your application configured for untrusted data. ### Workarounds If upgrading MessagePack to a patched version is not an option for you, you may apply a manual workaround a...

A vulnerability, which was classified as critical, was found in flairNLP flair 0.14.0. Affected is the function ClusteringModel of the file flair\models\clustering.py of the component Mode File Loader. The manipulation leads to code injection. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

### Impact A denial-of-service was found in Exiv2 version v0.28.1: an unbounded recursion can cause Exiv2 to crash by exhausting the stack. The vulnerable function, `QuickTimeVideo::multipleEntriesDecoder`, was new in v0.28.0 (see https://github.com/Exiv2/exiv2/pull/2337), so Exiv2 versions before v0.28 are _not_ affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted video file. ### Patches The bug is fixed in version v0.28.2. ### For more information Please see our [security policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security. ### Credit This bug was found by [OSS-Fuzz](https://github.com/google/oss-fuzz).

### Impact An out-of-bounds read was found in Exiv2 version v0.28.1.
