Hi,

The following vulnerabilities were published for zabbix.

CVE-2025-49641[0]:
| A regular Zabbix user with no permission to the Monitoring ->
| Problems view is still able to call the problem.view.refresh action
| and therefore still retrieve a list of active problems.


CVE-2025-27238[1]:
| Due to a bug in Zabbix API, the hostprototype.get method lists all
| host prototypes to users that do not have any user groups assigned
| to them.


CVE-2025-27236[2]:
| A regular Zabbix user can search other users in their user group via
| Zabbix API by select fields the user does not have access to view.
| This allows data-mining some field values the user does not have
| access to.


CVE-2025-27233[3]:
| Zabbix Agent 2 smartctl plugin does not properly sanitize
| smart.disk.get parameters, allowing an attacker to inject unexpected
| arguments into the smartctl command. This can be used to leak the
| NTLMv2 hash from a Windows system.


CVE-2025-27231[4]:
| The LDAP 'Bind password' value cannot be read after saving, but a
| Super Admin account can leak it by changing LDAP 'Host' to a rogue
| LDAP server. To mitigate this, the 'Bind password' value is now
| reset on 'Host' change.


If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
