CVE-2026-23928 (GCVE-0-2026-23928)
Vulnerability from cvelistv5 – Published: 2026-05-06 07:00 – Updated: 2026-05-06 12:59
VLAI?
Title
Stored XSS vulnerability in the Item history/Plain text widget
Summary
The Item history widget (in Zabbix 7.0+) or the Plain text widget (in Zabbix 6.0) can execute injected JavaScript when HTML display is enabled. This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malicious JavaScript would have to come from a monitored host controlled by the attacker. Note: the Item history widget is a replacement for the Plain text widget since Zabbix 7.0.

Title
Blind, read-only SQL injection in Zabbix API via sortfield parameter
Summary
A low privilege Zabbix user with API access can exploit a blind SQL injection vulnerability in include/classes/api/CApiService.php to execute arbitrary SQL selects via the sortfield parameter. Although query results are not returned directly, an attacker can exfiltrate arbitrary database data through time-based techniques, potentially leading to session identifier disclosure and administrator account compromise.
Severity ?

Title
Host and event action script regex validation can be bypassed in certain situations, leading to potential command injection
Summary
Host and event action script input is validated with a regex (set by the administrator), but the validation runs in multiline mode. If ^ and $ anchors are used in user input validation, an injected newline lets authenticated users bypass the check and inject shell commands.

CVE-2026-23919 (GCVE-0-2026-23919)

Title
Insufficient isolation of JavaScript (Duktape) execution context on Zabbix Server
Summary
For performance reasons Zabbix Server/Proxy reuses JavaScript (Duktape) contexts (used in script items, JavaScript reprocessing, Webhooks). This can lead to confidentiality loss where a regular (non-super) Zabbix administrator leaks data for hosts they do not have access to. A fix has been released that makes the built in Zabbix JavaScript objects read-only, but please be advised that usage of global JavaScript variables is not recommended because their content could be leaked. More information <a href='https://www.zabbix.com/documentation/7.4/en/manual/installation/known_issues#preprocessing-global-variables-are-unsafe'>in Zabbix documentation</a>.

Title
Unauthorized host creation via configuration.import API by low-privilege user with write permissions
Summary
An authenticated Zabbix user (User role) with template/host write permissions is able to create objects via the configuration.import API. This can lead to confidentiality loss by creating unauthorized hosts. Note that the User role is normally not sufficient to create and edit templates/hosts even with write permissions.

Title
Zabbix Agent 2 smartctl plugin argument injection in Zabbix 6.0 and later.
Summary
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.
Severity ?

Title
Media Types: Office365, SMTP passwords are unencrypted and visible in plaintext when exported
Summary
When exporting media types, the password is exported in the YAML in plain text. This appears to be a best practices type issue and may have no actual impact. The user would need to have permissions to access the media types and therefore would be expected to have access to these passwords.

Title
New line injection in Zabbix SNMP traps
Summary
The researcher is showing that due to the way the SNMP trap log is parsed, an attacker can craft an SNMP trap with additional lines of information and have forged data show in the Zabbix UI. This attack requires SNMP auth to be off and/or the attacker to know the community/auth details. The attack requires an SNMP item to be configured as text on the target host.

CVE-2024-42331 (GCVE-0-2024-42331)
Vulnerability from cvelistv5 – Published: 2024-11-27 12:06 – Updated: 2025-11-03 22:04

Title
Use after free in browser_push_error
Summary
In the src/libs/zbxembed/browser.c file, the es_browser_ctor method retrieves a heap pointer from the Duktape JavaScript engine. This heap pointer is subsequently utilized by the browser_push_error method in the src/libs/zbxembed/browser_error.c file. A use-after-free bug can occur at this stage if the wd->browser heap pointer is freed by garbage collection.
