How to Fix CVE-2026-97230

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-97230, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

IO::Socket::SSL::SelfCertificate versions 1.00 for Perl contains malware which executes Python code from an obfuscated URL. The generate_certificate runs a Python script saved as a certificate file. The pyhton script attempts to retrieve code from a hardcoded http URL that is obfuscated with base64 encoding and run the response body directly. The impact is that arbitrary code can be invoked as the user, without a dropped script being saved on the affected host. The releases have no test scripts nor build hooks. The intention may have been to trigger the payload after installation. The dropper script is in lib/Crypt/SelfCertificate/sample/cert.pem. This is similar to CVE-2026-95831 for the module Crypt::SelfCertificate. The SHA-256 digests of the files are ba24ee8ec3b7f47f65bed62e16fb413ace50653cf44bd8ea90914390922831e0 IO-Socket-SSL-SelfCertificate-1.00.tar.gz 821d38830e5eb8607738421c25ac25f59fff02a6ab67daa32fbd020429454dac IO-Socket-SSL-SelfCertificate-1.00/lib/IO/Socket/SSL/SelfCertificate/sample/cert.pem d483cb7b23b7271cb11cf242bff4a2e1c02df0b9525eb0429abeea8961c399d5 IO-Socket-SSL-SelfCertificate-1.00-upload.tar.gz
