CVE-2024-52577: Apache Ignite: Possible RCE when deserializing incoming messages by the server node

Severity: critical (CVSS 9.0 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 3.1% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2025-02-14 · updated 2026-06-17
Weakness: CWE-502

Description

In Apache Ignite versions from 2.6.0 and before 2.17.0, configured Class Serialization Filters are ignored for some Ignite endpoints. The vulnerability could be exploited if an attacker manually crafts an Ignite message containing a vulnerable object whose class is present in the Ignite server classpath and sends it to Ignite server endpoints. Deserialization of such a message by the Ignite server may result in the execution of arbitrary code on the Apache Ignite server side.

Affected products

Apache Software Foundation Apache Ignite: from 2.6.0 before 2.17.0 — fixed in 2.17.0

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Ignite 2.17.0. Check the vendor advisory for mitigations.
