Critical ShareFile Flaws Lead to Unauthenticated RCE

Two critical-severity vulnerabilities in the ShareFile content collaboration platform can be chained to achieve unauthenticated remote code execution by abusing an Execution After Redirect flaw and an arbitrary file upload bug. Both issues (CVE-2026-2699 and CVE-2026-2701) were reported to ShareFile and fixed in version 5.12.4; ShareFile 6.x is not affected. #ShareFile #CVE-2026-2699
