CVE-2026-8180Network attack vector

Unauthenticated service crash via null pointer dereference

Published May 27, 2026 · Updated May 27, 2026

NULL pointer dereference in asperahttpd in IBM Aspera HSTE and HSTS 3.7.4 through 4.4.7 Fix Pack 1 allows remote attackers to crash the service. IBM has not disclosed the request or code path that dereferences the null pointer, so the precise malformed input is not public. The asperahttpd listener is network reachable without authentication, and successful exploitation terminates that service without reported data disclosure or modification.
