How severe is CVE-2024-47561?

No CVSS score has been assigned to CVE-2024-47561 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2024-47561?

CVE-2024-47561 affects the following packages: org.apache.avro:avro (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-47561?

Update org.apache.avro:avro to 1.11.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-47561 is resolved across your whole dependency graph.

How do I detect CVE-2024-47561 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.avro:avro, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-47561 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2024-47561?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-47561 can be triaged on real exposure rather than presence alone.

Is CVE-2024-47561 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-47561 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-47561?

CVE-2024-47561 has an EPSS (Exploit Prediction Scoring System) score of 3.3%, placing it in the 88th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-47561?

CVE-2024-47561 is classified as Deserialization of Untrusted Data (CWE-502). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2024-47561 published, and has it been updated?

CVE-2024-47561 was published on October 3, 2024 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatCritical

The Red Hat build of Apache Camel K 1.10 was rated Important as it allows users to provide an Avro schema for parsing. Note that this functionality is limited to authenticated users. Red Hat Single Sign-On 7 ships the affected component in its maven repository but does not use it in the product. As such it is affected…
