Which packages are affected by GHSA-99px-7724-484v?

GHSA-99px-7724-484v affects the following packages: org.apache.any23:apache-any23 (Maven). Ecosystems affected: Maven.

How do I fix GHSA-99px-7724-484v?

Update org.apache.any23:apache-any23 to 2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-99px-7724-484v is resolved across your whole dependency graph.

How do I detect GHSA-99px-7724-484v in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.any23:apache-any23, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-99px-7724-484v 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-99px-7724-484v?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-99px-7724-484v can be triaged on real exposure rather than presence alone.

Is GHSA-99px-7724-484v actively exploited in the wild?

No public exploit code has been indexed for GHSA-99px-7724-484v 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-99px-7724-484v?

GHSA-99px-7724-484v has an EPSS (Exploit Prediction Scoring System) score of 5.7%, placing it in the 93th 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.

When was GHSA-99px-7724-484v published, and has it been updated?

GHSA-99px-7724-484v was published on September 13, 2021 and was last updated on December 2, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

GHSA-99px-7724-484v plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description

A Remote Code Execution (RCE) vulnerability was discovered in the Any23 YAMLExtractor.java file and is known to affect Any23 versions < 2.5. RCE vulnerabilities allow a malicious actor to execute any code of their choice on a remote machine over LAN, WAN, or internet. RCE belongs to the broader class of arbitrary code execution (ACE) vulnerabilities.
