GHSA-5rc6-9qfp-8vwg
MEDIUMGHSA-5rc6-9qfp-8vwg is a medium-severity (CVSS 6.3) Deserialization of Untrusted Data vulnerability in org.apache.camel:camel-consul. O3 Security confirms whether GHSA-5rc6-9qfp-8vwg is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache Camel-Consul component vulnerable to Deserialization of Untrusted Data
Blast Radius
org.apache.camel:camel-consul☕org.apache.camel:camel-consulReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
The ConsulRegistry in the camel-consul component (class org.apache.camel.component.consul.ConsulRegistry and its inner ConsulRegistryUtils.deserialize method) read Java-serialized values from the Consul KV store and passed them to ObjectInputStream.readObject() without configuring an ObjectInputFilter. An attacker who can write to the Consul KV store backing a Camel ConsulRegistry instance could inject a malicious serialized Java object that is deserialized the next time Camel performs a lookup against that registry, leading to arbitrary code execution in the Camel process. The issue mirrors the class of vulnerability already addressed for other Camel components in CVE-2024-22369, CVE-2024-23114 and CVE-2026-25747, and was overlooked during the original remediation of those CVEs.
This issue affects Apache Camel: from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.1.
Users are recommended to upgrade to version 4.19.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.6. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.camel:camel-consul. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.apache.camel:camel-consul to 4.14.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5rc6-9qfp-8vwg is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-5rc6-9qfp-8vwg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-5rc6-9qfp-8vwg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-5rc6-9qfp-8vwg in your dependencies?
O3 detects GHSA-5rc6-9qfp-8vwg across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
