Vulnerability details
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The Debian python-rdflib-tools 4.2.2-1 package for RDFLib 4.2.2 has CLI tools that can load Python modules from the current working directory, allowing code injection, because "python -m" looks in this directory, as demonstrated by rdf2dot.
