CVE-2026-7770Network attack vector

Authenticated remote code execution

Published Jun 1, 2026 · Updated Jun 1, 2026

Remote code execution in Access Client Solutions (ACS) 1.1.5.0 through 1.1.9.12 allows remote authenticated users to run arbitrary code. IBM has not disclosed the affected downstream component, the special elements accepted from Navigator requests, or the unsafe output operation. Exposure requires ACS to listen for Navigator requests; exploitation grants code execution in the ACS process context.
