core-framework: Improper Privilege Management
CVE-2025-71421 is a high-severity improper privilege management vulnerability in core-framework from Uvdesk, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 1.1.7 as the first without the flaw, so updating core-framework to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.64% chance of exploitation within 30 days, higher than 51% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update core-framework to 1.1.7 or a later version.
- Update community-skeleton to 1.1.8 or a later version.

Official description
UVdesk core-framework before 1.1.7 contains an improper privilege management vulnerability in the editAgent endpoint that allows agents with agent-management privilege to escalate their own role to administrator. Attackers can submit their own account identifier with a role parameter set to ROLE_ADMIN to gain full administrative control over agents, tickets, and mail configuration.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
