CVE-2026-67602
CriticalCVSS 9.1Summary
phpIPAM before 1.8.2 contains an authentication bypass vulnerability in the REST API that allows unauthenticated attackers to gain full API access by exploiting an insecure object cache keying mechanism. The cache is keyed by lookup value alone without including the searched column, enabling an entry written during an app_id lookup to satisfy a subsequent app_code lookup, allowing attackers to use the numeric database row identifier as an API token to read, write, and delete all IP address management records.
Risk Assessment
The risk includes complete compromise of the IP address management system, including unauthorized read, modification, and deletion of all records, potentially leading to network disruption and data confidentiality breach.
Recommendation
It is recommended to immediately update phpIPAM to version 1.8.2 or later, which fixes this vulnerability, and to implement additional authentication mechanisms for API access.
