Technical Analysis
This vulnerability (CWE-405) affects IBM DataPower Gateway versions 10.5.0.0 to 10.5.0.22, 10.6.0.0 to 10.6.0.10, 10.6.1 to 10.6.6, and 11.0.0.0 to 11.0.0.2. The flaw is due to improper memoization of GraphQL fragment spreads, which allows a remote attacker to trigger asymmetric resource consumption leading to denial of service. The CVSS v3.1 base score is 7.5, indicating high severity, with network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability.
Potential Impact
Successful exploitation results in denial of service by exhausting resources on the affected IBM DataPower Gateway devices. There is no impact on confidentiality or integrity according to the CVSS vector. No known exploits are reported in the wild at this time.
Mitigation Recommendations
No explicit patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is available, consider limiting exposure of affected services to untrusted networks to reduce risk.
