Denial of service vulnerability present shortly after product installation or upgrade, potentially allowed an attacker to render ESET’s security product inoperable, provided non-default preconditions were met.

The Premium Portfolio Features for Phlox theme plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Grid Portfolios Widget in all versions up to, and including, 2.3.2 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.

The WP Event Manager – Events Calendar, Registrations, Sell Tickets with WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'events' shortcode in all versions up to, and including, 3.1.43 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.

The Brizy – Page Builder plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'update_item' function in all versions up to, and including, 2.4.44. This makes it possible for authenticated attackers, with contributor access and above, to modify the content of arbitrary published posts, which includes the ability to insert malicious JavaScript.

The Glossary plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 2.2.26. This is due the plugin utilizing wpdesk and not preventing direct access to the test files along with display_errors being enabled. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

The AForms — Form Builder for Price Calculator & Cost Estimation plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 2.2.6. This is due to the plugin utilizing the aura library and allowing direct access to the phpunit test files. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

The WordPress File Upload plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 4.24.7 via the 'uploadpath' parameter of the wordpress_file_upload shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload limited files to arbitrary locations on the web server.

In the Linux kernel, the following vulnerability has been resolved:

USB: core: Fix race by not overwriting udev->descriptor in hub_port_init()

Syzbot reported an out-of-bounds read in sysfs.c:read_descriptors():

As analyzed by Khazhy Kumykov, the cause of this bug is a race between
read_descriptors() and hub_port_init(): The first routine uses a field
in udev->descriptor, not expecting it to change, while the second
overwrites it.

Prior to commit 45bf39f8df7f ("USB: core: Don't hold device lock while
reading the "descriptors" sysfs file") this race couldn't occur,
because the routines were mutually exclusive thanks to the device
locking. Removing that locking from read_descriptors() exposed it to
the race.

The best way to fix the bug is to keep hub_port_init() from changing
udev->descriptor once udev has been initialized and registered.
Drivers expect the descriptors stored in the kernel to be immutable;
we should not undermine this expectation. In fact, this change should
have been made long ago.

So now hub_port_init() will take an additional argument, specifying a
buffer in which to store the device descriptor it reads. (If udev has
not yet been initialized, the buffer pointer will be NULL and then
hub_port_init() will store the device descriptor in udev as before.)
This eliminates the data race responsible for the out-of-bounds read.

The changes to hub_port_init() appear more extensive than they really
are, because of indentation changes resulting from an attempt to avoid
writing to other parts of the usb_device structure after it has been
initialized. Similar changes should be made to the code that reads
the BOS descriptor, but that can be handled in a separate patch later
on. This patch is sufficient to fix the bug found by syzbot.

The Web and WooCommerce Addons for WPBakery Builder plugin for WordPress is vulnerable to unauthorized plugin settings modification due to a missing capability check on several plugin functions in all versions up to, and including, 1.4.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change some of the plugin settings.

An SQL Injection vulnerability in Apache Superset exists due to improper neutralization of special elements used in SQL commands. Specifically, certain engine-specific functions are not checked, which allows attackers to bypass Apache Superset's SQL authorization. To mitigate this, a new configuration key named DISALLOWED_SQL_FUNCTIONS has been introduced. This key disallows the use of the following PostgreSQL functions: version, query_to_xml, inet_server_addr, and inet_client_addr. Additional functions can be added to this list for increased protection.

This issue affects Apache Superset: before 4.0.2.

Users are recommended to upgrade to version 4.0.2, which fixes the issue.
