CVE-2026-59785 Zabbix CVE debrief

A user with read access can filter host search results in Frontend by fields that are not displayed, including stored IPMI and PSK credentials. This allows them to guess a credential and verify the guess through search results, potentially uncovering it. The vulnerability enables credential guessing and exposure through host search filtering, allowing users to verify guesses and potentially uncover credentials. Defenders should assess exposure and prioritize verification of exposed systems, access controls, and monitoring for unauthorized access attempts. The CVE record and NVD entry provide details on the vulnerability, but additional information from the vendor and other sources,

Who should care

Defenders responsible for systems using Zabbix should assess exposure and prioritize verification of exposed systems, access controls, and monitoring for unauthorized access attempts.

Why it matters

Defenders should care about CVE-2026-59785 because it allows users with read access to potentially guess and expose IPMI and PSK credentials through host search filtering. This requires verification of exposed systems, access controls, and monitoring for unauthorized access attempts.

  • Credential guessing and exposure
  • Potential unauthorized access to sensitive information
  • Need for enhanced access controls and monitoring

Technical summary

The vulnerability allows users with read access to filter host search results by hidden fields, including IPMI and PSK credentials. This could enable them to guess credentials and verify the guess through search results. The issue arises from the ability to filter search results by fields that are not displayed, such as IPMI and PSK credentials, potentially leading to credential exposure. Users with read access can exploit this to guess and verify credentials, which may result in unauthorized access to sensitive information. The vulnerability requires verification

Defensive priority

Defenders should prioritize verifying exposed systems, restricting access to sensitive information, and monitoring for unauthorized access attempts.

Recommended defensive actions

  • Verify and restrict access to sensitive information
  • Monitor for unauthorized access attempts
  • Implement additional security measures to protect against credential guessing

Evidence notes

The CVE record and NVD entry provide details on the vulnerability. However, additional information from the vendor and other sources may be necessary to fully understand the issue.
