| CVE | Severity | CVSS | Summary | Published |
|---|---|---|---|---|
| CVE-2026-59781(opens NVD record) | High | 7.8 | When Zabbix Agent was installed on Windows into a custom installation directory, the installer did not verify whether the selected directory had secure access permissions. If the target directory allowed unauthorized users to modify its contents, an attacker could place a malicious DLL that could later be loaded by the application, resulting in DLL sideloading. The installer has been hardened to detect potentially unsafe installation directories and now requires explicit user confirmation before proceeding with installation in such locations. This reduces the risk of accidental installation into directories with inappropriate permissions while preserving compatibility with existing deployment scenarios. | Aug 18, 2026 |
| CVE-2026-23938(opens NVD record) | Medium | 4.9 | An authenticated administrator is able to crash Zabbix server or proxy by creating specifically crafted preprocessing/script item JavaScript scripts, leading to potential denial of service. | Aug 18, 2026 |
| CVE-2026-23937(opens NVD record) | Medium | 6.5 | The Zabbix API host.get action can be exploited by authenticated users to extract a host's PSK key leading to potential loss of data integrity. | Aug 18, 2026 |
| CVE-2026-23935(opens NVD record) | Medium | 4.9 | A Zabbix administrator is able to read out of bounds memory by utilizing a flaw in script item/preprocessing (JavaScript) HttpRequest logic, leading to potential confidentiality loss. | Aug 18, 2026 |
| CVE-2026-23934(opens NVD record) | Medium | 6.5 | An authenticated user is able to cause disproportionate CPU load on the Frontend webserver by sending specifically crafted requests to the Frontend validate.api.exists action, leading to potential denial of service. | Aug 18, 2026 |
| CVE-2026-23933(opens NVD record) | Critical | 9.1 | In Zabbix 7.4 the cryptographic key used for signing Frontend sessions has been erroneously written to the database seed. Currently the only known exploitation scenario is for deployments that utilize both - SAML authentication and guest users. In such cases the key can be used to forge valid session cookies, potentially leading to unauthorized access. For other Zabbix deployments this does not have a known impact. | Aug 18, 2026 |
| CVE-2026-23931(opens NVD record) | Medium | 4.3 | The frontend validatate.api.exists action can be exploited by authenticated users to extract plaintext user macro values leading to potential loss of confidentiality. | Aug 18, 2026 |
| CVE-2026-23930(opens NVD record) | High | 7.5 | An unauthenticated user is able to cause disproportionate CPU load on the Frontend webserver by sending specifically crafted requests to the Frontend popup.testtriggerexpr action, leading to potential denial of service. | Aug 18, 2026 |
| CVE-2026-23929(opens NVD record) | Medium | 5.4 | Prototype pollution vulnerability in searchParamsToObject() is leading to a persistent XSS in Maps. URL parameter processing was not filtering dangerous properties like __proto__, combined with jQuery's unsafe element creation that traversed the prototype chain. | Aug 18, 2026 |
| CVE-2026-23922(opens NVD record) | Medium | 4.9 | The email media OAuth field 'Client secret' cannot be read after saving, but a Super Admin can leak it by setting a malicious 'Token endpoint'. Changes were made to reset the client secret upon changing the token endpoint. | Aug 18, 2026 |
| CVE-2026-1199(opens NVD record) | Low | 3.7 | Zabbix API and Frontend login lockout mechanism has a flaw where several unsuccessful login requests are not properly counted towards the block counter if sent simultaneously, potentially allowing for more password guesses than intended. | Aug 18, 2026 |
| CVE-2026-23928(opens NVD record) | Medium | 6.8 | 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. | May 6, 2026 |
