Unauthenticated remote RCE in IBM DataPower, a widely deployed enterprise gateway appliance — high-impact, likely to disrupt organizations and demand broad IT attention.
CVE-2026-14269
Unauthenticated heap overflow in IBM DataPower enabling remote code execution
Is CVE-2026-14269 being exploited?
Not confirmed. CVE-2026-14269 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.48% probability of exploitation in the next 30 days.
How severe is CVE-2026-14269?
CVE-2026-14269 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-14269?
Not known from our data. No patch reference has been recorded for CVE-2026-14269, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.
What does CVE-2026-14269 affect?
CVE-2026-14269 affects IBM DataPower Gateway 10.5.0.0 - 10.5.0.22, IBM DataPower Gateway 10.6.0.0 - 10.6.0.10, IBM DataPower Gateway 10.6.1 - 10.6.6, IBM DataPower Gateway 11.0.0.0 - 11.0.0.2. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-14269?
Apply vendor updates ASAP; isolate devices and restrict network access to DataPower.
