CVE-2026-17440
MediumCVSS 5.5Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
IBM App Connect Enterprise and IBM Integration Bus for z/OS are vulnerable to uncontrolled recursion, which could lead to denial of service. A local attacker could exploit this.
Risk Assessment
A denial of service attack could make critical integration applications unavailable, disrupting business operations.
Recommendation
Upgrade to a patched version and monitor systems for unusual activity.

IBM App Connect Enterprise versions 13.0.1.0 through 13.0.7.2 and 12.0.1.0 through 12.0.12.27 are vulnerable to remote directory traversal. An attacker can send a specially crafted URL containing '/../' sequences to write arbitrary files on the system.
- CVE-2026-17416High
IBM App Connect Enterprise 13.0.1.0 through 13.0.8.0, and 12.0.1.0 through 12.0.12.27 could allow a local attacker to execute arbitrary code due to insecure deserialization.
- CVE-2026-17156High
IBM App Connect Enterprise 13.0.1.0 through 13.0.8.0, and 12.0.1.0 through 12.0.12.27 could allow a local attacker to execute arbitrary code due to insecure deserialization.
- CVE-2026-17133High
IBM App Connect Enterprise 13.0.1.0 through 13.0.8.0, and 12.0.1.0 through 12.0.12.27 could allow a local attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
- CVE-2026-75624High
IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.1 and 12.0.1.0 through 12.0.12.27 allow a remote authenticated attacker to bypass security restrictions due to incorrect authorization.
- CVE-2026-17444Medium
IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.1 and 12.0.1.0 through 12.0.12.28, and IBM Integration Bus for z/OS versions 10.1.0.0 through 10.1.0.7 could allow a remote authenticated attacker to obtain sensitive information due to an XML external entity (XXE) injection.
- CVE-2026-17443Medium
IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.1 and 12.0.1.0 through 12.0.12.28, and IBM Integration Bus for z/OS versions 10.1.0.0 through 10.1.0.7 could allow a remote authenticated attacker to obtain sensitive information due to an XML external entity (XXE) injection flaw.
- CVE-2026-17442Medium
IBM App Connect Enterprise and IBM Integration Bus for z/OS write credentials in cleartext to trace logs. A local attacker could access this sensitive information.
- CVE-2026-16689Medium
IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.1 and 12.0.1.0 through 12.0.12.28, and IBM Integration Bus for z/OS versions 10.1.0.0 through 10.1.0.7 could allow a local attacker to obtain sensitive information due to improper logging of credentials.
- CVE-2026-16180Medium
IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.1 and 12.0.1.0 through 12.0.12.28, and IBM Integration Bus for z/OS versions 10.1.0.0 through 10.1.0.7 Toolkit could allow an authenticated user to cause a denial-of-service condition due to improper validation of XML entities.
