CVE-2026-16180
MediumCVSS 5.7Exploitation Probability (EPSS)
Low risk12th percentile - higher than 12% of all known CVEs
Summary
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.
Risk Assessment
An authenticated user could overload the system, potentially leading to unavailability of the Toolkit and disruption of operations.
Recommendation
Update the software to patched versions and restrict access to the Toolkit to trusted users only.

See all- CVE-2026-15435Critical
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-2026-17440Medium
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.
- 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.
