CVE-2026-81832
HighCVSS 7.7Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
IBM App Connect Enterprise and IBM Integration Bus for z/OS with SAP Adapter are vulnerable to an XML External Entity (XXE) attack. Affected versions include 13.0.1.0 through 13.0.8.1, 12.0.1.0 through 12.0.12.28, and 10.1.0.0 through 10.1.0.7.
Risk Assessment
An XXE attack could allow reading files from the server, performing SSRF attacks, or causing denial of service, potentially exposing sensitive data and compromising system integrity.
Recommendation
It is recommended to immediately update the software to a patched version and implement XXE protections, such as disabling external XML entities.
