CVE-2026-14521 IBM CVE debrief

Who should care

Defenders and security teams responsible for IBM DataPower Gateway systems, especially those using affected versions, should assess exposure and potential impact. Network administrators and security professionals should verify system configurations and apply patches or updates as needed.

Why it matters

IBM DataPower Gateway's SSRF vulnerability allows authenticated attackers to send unauthorized requests, potentially leading to network enumeration or other attacks. Defenders should verify exposure, assess impact, and apply patches or updates for affected versions.

• Network enumeration may be possible through SSRF exploitation.
• Other attacks could be facilitated through unauthorized requests.
• Verification of system configurations and patch levels is necessary.
• Monitoring for suspicious activity indicative of SSRF exploitation is recommended.

Technical summary

IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 are vulnerable to server-side request forgery (SSRF). An authenticated attacker may send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks. The vulnerability allows attackers to bypass security controls and access internal resources, potentially leading to further exploitation. Defenders should prioritize verifying exposure and assessing potential impact on their systems, especially those using affected versions.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impact on their systems, especially those using IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2.

Recommended defensive actions

• Verify system exposure by checking if IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, or 11.0.0.0 through 11.0.0.2 are in use.
• Assess potential impact on network enumeration and other attacks facilitated by SSRF.
• Review and apply vendor-provided patches or updates for affected versions.
• Monitor system activity for unauthorized requests indicative of SSRF exploitation.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes
