The package 'vcsfossilpdfx1' in the RubyGems ecosystem, specifically version 0.0.1, has been flagged as malicious by the OpenSSF and recorded in the GCVE database under MAL-2026-9113. There is no detailed technical description of the malicious behavior or exploitation method. No patch or remediation information is provided, indicating that the package itself is inherently malicious rather than vulnerable in the traditional sense.

Use of this package version may lead to execution of malicious code, potentially compromising systems where it is installed. However, no known exploits in the wild have been reported. The impact is primarily the risk of introducing malicious functionality into dependent software environments.

Avoid using the 'vcsfossilpdfx1' package version 0.0.1. Remove it from any environments where it is installed. Since this is a malicious package, remediation involves not installing or uninstalling the package rather than applying a patch. Monitor official RubyGems advisories and OpenSSF updates for any further guidance.
