CVE-2026-59785Hinoki check available

Credential inference via hidden host search filters

Published Oct 5, 2026 · Updated Oct 5, 2026

Zabbix Frontend 6.0.0 through 6.0.47, 7.0.0 through 7.0.28, and 7.4.0 through 7.4.12 lets remote authenticated users infer host credentials. Frontend host search filters on undisplayed IPMI and PSK credential fields, so a matching result confirms a guessed value without displaying the field. Exploitation requires host read access and access to the frontend from an adjacent network; the disclosed effect is credential inference, not direct credential listing.
