Last modified
CVE-2026-71560 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. Out-of-bounds Read vulnerability in Apache Fory C++ deserialization. This issue affects Apache Fory C++ versions from 0.14.0 before 1.5.0 when deserializing structs containing tagged integer fields. A crafted input payload may trigger an out-of-bounds heap read in the tagged integer fast-path deserializer, potentially causing information disclosure or denial of service. Users are recommended to upgrade to Apache Fory 1.5.0, which fixes this issue. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
