The WP Easy Post Types plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to a missing capability check on multiple functions in all versions up to, and including, 1.4.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to add, modify, or delete plugin options and posts.
The Click to Chat – WP Support All-in-One Floating Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpsaio_snapchat shortcode in all versions up to, and including, 2.3.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE-2024-49281 may be a duplicate of this issue.
The Add Widget After Content plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.4.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
The Parcel Pro plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'action' parameter in all versions up to, and including, 1.8.4 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.
The DPD Baltic Shipping plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'search_value' parameter in all versions up to, and including, 1.2.83 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.
The GetResponse Forms by Optin Cat plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.5.7. 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.
SECOM WRTR-304GN-304TW-UPSC does not properly filter user input in the specific functionality. Unauthenticated remote attackers can exploit this vulnerability to inject and execute arbitrary system commands on the device.
Improper Validation of Specified Quantity in Input vulnerability in Mitsubishi Electric CNC Series allows a remote unauthenticated attacker to cause Denial of Service (DoS) condition on the product by sending specially crafted packets to TCP port 683, causing an emergency stop.
Cross Site Scripting vulnerability in JavaScript Library jquery-ui v.1.13.1 allows a remote attacker to obtain sensitive information and execute arbitrary code via a crafted payload to the window.addEventListener component. NOTE: this is disputed by the Supplier because it cannot be reproduced, and because the exploitation example does not indicate whether, or how, the example website is using jQuery UI.
### 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 as follows:
1. Declare a class that derives from `MessagePackSecurity`.
2. Override the `GetHashCollisionResistantEqualityComparer<T>` method to provide a collision-resistant hash function of your own and avoid calling `base.GetHashCollisionResistantEqualityComparer<T>()`.
3. Configure a `MessagePackSerializerOptions` with an instance of your derived type by calling `WithSecurity` on an existing options object.
4. Use your custom options object for all deserialization operations. This may be by setting the `MessagePackSerializer.DefaultOptions` static property, if you call methods that rely on this default property, and/or by passing in the options object explicitly to any `Deserialize` method.

Tacquito prior to commit 07b49d1358e6ec0b5aa482fcd284f509191119e2 was not properly performing regex matches on authorized commands and arguments. Configured allowed commands/arguments were intended to require a match on the entire string, but instead only enforced a match on a sub-string. That would have potentially allowed unauthorized commands to be executed.
