CVE-2026-17392 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 9.9 (critical) and affects API Connect; fixed in 12.1.1.3.

## Affected

- IBM API Connect: from 12.1.0.0, through 12.1.1.2; from 10.0.8.0, through 10.0.8.12

## Description

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to gain unauthorized administrative access to other tenants due to LDAP injection. User-supplied input is not properly neutralized in directory queries, which could change the query and grant access beyond the user's own tenant.
