Which packages are affected by GHSA-2rmm-87v7-34rj?

GHSA-2rmm-87v7-34rj affects the following packages: org.apache.any23:apache-any23 (Maven). Ecosystems affected: Maven.

How do I fix GHSA-2rmm-87v7-34rj?

Update org.apache.any23:apache-any23 to 2.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2rmm-87v7-34rj is resolved across your whole dependency graph.

How do I detect GHSA-2rmm-87v7-34rj 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. 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-2rmm-87v7-34rj 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-2rmm-87v7-34rj?

O3 pinpoints whether GHSA-2rmm-87v7-34rj 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-2rmm-87v7-34rj actively exploited in the wild?

No public exploit code has been indexed for GHSA-2rmm-87v7-34rj 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-2rmm-87v7-34rj?

GHSA-2rmm-87v7-34rj has an EPSS (Exploit Prediction Scoring System) score of 2.7%, placing it in the 84th 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-2rmm-87v7-34rj?

GHSA-2rmm-87v7-34rj is classified as XML External Entity (XXE) (CWE-611). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-2rmm-87v7-34rj published, and has it been updated?

GHSA-2rmm-87v7-34rj was published on March 6, 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

An XML external entity (XXE) injection vulnerability was discovered in the Any23 RDFa XSLTStylesheet extractor and is known to affect Any23 versions < 2.7. XML external entity injection (also known as XXE) is a web security vulnerability that allows an attacker to interfere with an application's processing of XML data. It often allows an attacker to view files on the application server filesystem, and to interact with any back-end or external systems that the application itself can access. This issue is fixed in Apache Any23 2.7.
