CVE-2026-85476: Apache Thrift infinite loop in c_glib bindings

CVE-2026-85476 · Severity: info · Published 2026-10-02

Apache Thrift is a framework for data serialization and RPC commonly used in distributed systems. An infinite loop vulnerability in its C GLib bindings could cause applications to hang or become unresponsive when processing malformed data. This may lead to denial of service conditions in services relying on Thrift for communication.

Technologies: Apache Thrift. Vendors: Apache.

Technical details

A loop with unreachable exit condition exists in the Apache Thrift c_glib bindings, potentially triggered when processing certain inputs. The vulnerability affects c_glib library code and could cause resource exhaustion through an infinite loop. A remote attacker could exploit this by sending malformed Thrift messages to trigger the unexitable loop condition.

Affected products

  • Apache Thrift before 0.25.0
