Apache disclosed CVE-2026-58389 in the Rust bindings for Apache Thrift, warning that versions before 0.24.0 contain a missing string size limit in the binary protocol's non-strict parsing path. The issue is classified as Allocation of Resources Without Limits or Throttling, meaning a crafted input could trigger excessive memory allocation during message processing.
The project said the flaw affects the Rust implementation of the cross-language RPC framework and advised users to upgrade to Apache Thrift 0.24.0 to remediate the problem. The vulnerability was credited to Javid Khan and disclosed publicly by Jens Geyer through the oss-sec mailing list.
