CVE-2026-27172: CWE-502 Deserialization of Untrusted Data in Apache Software Foundation Apache Camel
Apache Camel's camel-consul component contains a deserialization vulnerability in the ConsulRegistry class, where untrusted Java-serialized data from the Consul KV store is deserialized without filtering. This allows an attacker with write access to the Consul KV store to inject malicious serialized objects, potentially leading to arbitrary code execution within the Camel process. The vulnerability affects Apache Camel versions from 3. 0. 0 before 4. 14. 6 and from 4. 15. 0 before 4. 18.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-27172) in Apache Camel's camel-consul component arises from deserializing Java objects from the Consul KV store without applying an ObjectInputFilter, enabling deserialization of untrusted data (CWE-502). An attacker able to write to the Consul KV store can inject malicious serialized Java objects, which are deserialized during Camel registry lookups, leading to arbitrary code execution in the Camel process. This vulnerability affects Apache Camel versions 3.0.0 up to but not including 4.14.6, and 4.15.0 up to but not including 4.18.1. The issue was missed in previous fixes for similar vulnerabilities (CVE-2024-22369, CVE-2024-23114, CVE-2026-25747). Users are advised to upgrade to Apache Camel 4.19.0 or the appropriate fixed versions 4.14.6 or 4.18.1 depending on their release stream.
Potential Impact
Successful exploitation allows an attacker with write access to the Consul KV store to execute arbitrary code within the Apache Camel process. This can lead to full compromise of the affected application environment running Camel. The vulnerability is critical due to the potential for remote code execution, but exploitation requires the attacker to have the ability to write to the Consul KV store backing the Camel ConsulRegistry instance.
Mitigation Recommendations
Users should upgrade Apache Camel to version 4.19.0, or if using the 4.14.x LTS stream, upgrade to 4.14.6, or if using the 4.18.x stream, upgrade to 4.18.1. These versions contain the official fix for this vulnerability. No other mitigations are specified. Patch status is confirmed by the vendor advisory recommending these upgrades.
