An unauthenticated P4Runtime client can achieve arbitrary code execution under certain conditions on affected platforms running Arista EOS configured with P4Runtime. By crafting a malicious packet during session initiation, an attacker can obtain complete administrative control over the switch.

In NLnet Labs Unbound up to and including 1.26.0, a vulnerability in the DNSSEC validator enables denial of service and possible remote code execution via DNSKEY processing. A crafted DNSKEY can overflow the digest buffer.

An unauthenticated remote attacker can upload a malicious IODD file that places and executes a shell script with root privileges. The script remains active even after a reboot.

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress in all versions up to and including 1.2.3 is vulnerable to authorization bypass.

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress in all versions up to and including 3.6.2 is vulnerable to Privilege Escalation. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This allows unauthenticated attackers to create a new administrator-level user account.

Under certain conditions a valid SAML IdP response may be used to impersonate another Secret Server user. The vulnerability affects the SAML authentication mechanism.
