CVE-2006-2112
HighSummary
A vulnerability in the Fuji Xerox FXPS print engine allows attackers to use the FTP printing interface as a proxy (FTP bounce). By manipulating PORT arguments in FTP requests, an attacker can connect to systems that would otherwise be restricted.
Risk Assessment
The risk involves bypassing network security controls and gaining unauthorized access to internal systems. An attacker can use the printer as a relay to scan or attack other devices on the network.
Recommendation
Update the device firmware to the versions recommended by the vendor (DocuPrint before 20060628, Network Option Card before 5.13). Additionally, restrict FTP interface access to trusted hosts only.

- CVE-2026-75816Critical
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.
- CVE-2026-16310Critical
The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 1.8.5 via the 'id' parameter due to missing validation on a user-controlled key. This allows unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification to the victim.
