Which packages are affected by GHSA-5xqm-hc45-f2g2?

GHSA-5xqm-hc45-f2g2 affects the following packages: co.elastic.apm:apm-agent-parent (Maven), co.elastic.apm:elastic-apm-agent (Maven). Ecosystems affected: Maven.

How do I fix GHSA-5xqm-hc45-f2g2?

Update co.elastic.apm:apm-agent-parent to 1.27.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5xqm-hc45-f2g2 is resolved across your whole dependency graph.

How do I detect GHSA-5xqm-hc45-f2g2 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for co.elastic.apm:apm-agent-parent. 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-5xqm-hc45-f2g2 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-5xqm-hc45-f2g2?

O3 pinpoints whether GHSA-5xqm-hc45-f2g2 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-5xqm-hc45-f2g2 actively exploited in the wild?

No public exploit code has been indexed for GHSA-5xqm-hc45-f2g2 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-5xqm-hc45-f2g2?

GHSA-5xqm-hc45-f2g2 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 16th 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-5xqm-hc45-f2g2?

GHSA-5xqm-hc45-f2g2 is classified as Improper Privilege Management (CWE-269). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-5xqm-hc45-f2g2 published, and has it been updated?

GHSA-5xqm-hc45-f2g2 was published on November 22, 2023 and was last updated on September 30, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-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

A local privilege escalation issue was found with the APM Java agent, where a user on the system could attach a malicious plugin to an application running the APM Java agent. By using this vulnerability, an attacker could execute code at a potentially higher level of permissions than their user typically has access to.
