Which packages are affected by GHSA-p76j-5v6v-6c22?

GHSA-p76j-5v6v-6c22 affects the following packages: org.apache.nifi:nifi (Maven). Ecosystems affected: Maven.

How do I fix GHSA-p76j-5v6v-6c22?

Update org.apache.nifi:nifi to 1.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p76j-5v6v-6c22 is resolved across your whole dependency graph.

How do I detect GHSA-p76j-5v6v-6c22 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.nifi:nifi. 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.

How do I mitigate GHSA-p76j-5v6v-6c22 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 GHSA-p76j-5v6v-6c22?

O3 pinpoints whether GHSA-p76j-5v6v-6c22 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-p76j-5v6v-6c22 actively exploited in the wild?

No public exploit code has been indexed for GHSA-p76j-5v6v-6c22 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 GHSA-p76j-5v6v-6c22?

GHSA-p76j-5v6v-6c22 has an EPSS (Exploit Prediction Scoring System) score of 3.2%, placing it in the 86th 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 GHSA-p76j-5v6v-6c22?

GHSA-p76j-5v6v-6c22 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 GHSA-p76j-5v6v-6c22 published, and has it been updated?

GHSA-p76j-5v6v-6c22 was published on May 14, 2022 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Apache NiFi JMS Deserialization issue because of ActiveMQ client vulnerability. Malicious JMS content could cause denial of service. See ActiveMQ CVE-2015-5254 announcement for more information. The fix to upgrade the activemq-client library to 5.15.3 was applied on the Apache NiFi 1.6.0 release. Users running a prior 1.x release should upgrade to the appropriate release.
