CVE-2026-42301

A flaw was found in pyp2spec, a tool that generates Fedora RPM spec files for Python projects. This vulnerability allows a malicious Python Package Index PyPI package to execute arbitrary commands on a build machine. This occurs because pyp2spec writes PyPI package metadata, such as the summary...

CVE-2026-42301

pyp2spec generates working Fedora RPM spec file for Python projects. Prior to version 0.14.1, pyp2spec was writing PyPI package metadata e.g. the summary field into the generated spec file without escaping RPM macro directives. When a packager then runs rpmbuild, those directives get evaluated, s...

CVE-2026-42301

CVE-2026-42301 affects pyp2spec. Prior to v0.14.1, it wrote PyPI metadata (e.g., summary) into the generated Fedora RPM spec file without escaping RPM macro directives, allowing a local attacker to execute arbitrary commands during rpmbuild. The issue is patched in v0.14.1; upgrade to 0.14.1 or l...
