IBM i is a widely used enterprise OS; authenticated remote code execution on core systems can disrupt business operations and data integrity.
CVE-2026-93886
Authenticated remote script execution via improper input validation in IBM i 7.3–7.6
Is CVE-2026-93886 being exploited?
Not confirmed. CVE-2026-93886 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 0.25% probability of exploitation in the next 30 days.
How severe is CVE-2026-93886?
CVE-2026-93886 is rated High with a CVSS score of 8.3. 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-2026-93886?
Not known from our data. No patch reference has been recorded for CVE-2026-93886, 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.
