GHSA-mqmp-4mcp-vg8v has a CVSS score of 7.5/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-mqmp-4mcp-vg8v?

GHSA-mqmp-4mcp-vg8v affects the following packages: org.apache.orc:orc (Maven). Ecosystems affected: Maven.

How do I fix GHSA-mqmp-4mcp-vg8v?

Update org.apache.orc:orc to 1.4.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mqmp-4mcp-vg8v is resolved across your whole dependency graph.

How do I detect GHSA-mqmp-4mcp-vg8v in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.orc:orc. 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-mqmp-4mcp-vg8v 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-mqmp-4mcp-vg8v?

O3 pinpoints whether GHSA-mqmp-4mcp-vg8v 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-mqmp-4mcp-vg8v actively exploited in the wild?

No public exploit code has been indexed for GHSA-mqmp-4mcp-vg8v 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-mqmp-4mcp-vg8v?

GHSA-mqmp-4mcp-vg8v has an EPSS (Exploit Prediction Scoring System) score of 3.5%, 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 GHSA-mqmp-4mcp-vg8v?

GHSA-mqmp-4mcp-vg8v is classified as CWE-674 (CWE-674). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-mqmp-4mcp-vg8v published, and has it been updated?

GHSA-mqmp-4mcp-vg8v was published on May 13, 2022 and was last updated on February 4, 2026. 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

In Apache ORC 1.0.0 to 1.4.3 a malformed ORC file can trigger an endlessly recursive function call in the C++ or Java parser. The impact of this bug is most likely denial-of-service against software that uses the ORC file parser. With the C++ parser, the stack overflow might possibly corrupt the stack.
