WordPress Core is vulnerable to Directory Traversal in versions up to, and including, 6.2, via the ‘wp_lang’ parameter. This allows unauthenticated attackers to access and load arbitrary translation files. In cases where an attacker is able to upload a crafted translation file onto the site, such as via an upload form, this could be also used to perform a Cross-Site Scripting attack.

CVSS v3 8.2
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Rockwell Automation
Equipment: FactoryTalk Linx
Vulnerability: Improper Input Validation
Successful exploitation of this vulnerability could lead to information disclosure or a denial-of-service condition.
The following versions of Rockwell products are affected:
FactoryTalk Linx: v6.20 and prior
3.2.1 IMPROPER INPUT VALIDATION CWE-20
FactoryTalk Linx, in the Rockwell Automation PanelView Plus, allows an unauthenticated threat actor to read data from memory via crafted malicious packets. Sending a size larger than the buffer size results in leakage of data from memory resulting in an information disclosure. If the size is large enough, it causes communications over the common industrial protocol to become unresponsive to any type of packet, resulting in a denial-of-service to FactoryTalk Linx over the common industrial protocol.
CVE-2023-29464 has been assigned to this vulnerability. A CVSS v3 base score of 8.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H).

Schneider Electric also recommends the following cybersecurity best practices:
Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
Place all controllers in locked cabinets and never leave them in the “Program” mode.
Never connect programming software to any network other than the network intended for that device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.
