An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-102930 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- virtualenv (Bitnami): affected all versions; fixed in 21.7.12\n- virtualenv (PyPI): affected all versions; fixed in 21.7.12\n- virtualenv (PyPI): affected all versions; fixed in 21.7.12\n- virtualenv (PyPI): affected all versions; fixed in 21.7.12\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-102930/ (Markdown: https://insights.sbomify.com/CVE-2026-102930/index.md)","id":"CVE-2026-102930","markdown":"https://insights.sbomify.com/CVE-2026-102930/index.md","name":"CVE-2026-102930","record":{"aliases":["AZL-105669","BIT-virtualenv-2026-102930","DEBIAN-CVE-2026-102930","ECHO-2248-faed-ae67","GHSA-94p9-xgh2-xp45","MINI-cpmh-xwwj-c7xf","MINI-jj2g-6j63-g478","PYSEC-2026-4011","ROOT-APP-PYPI-CVE-2026-102930","UBUNTU-CVE-2026-102930"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Python virtualenv tool","requires_auth":"none","summary":"Attackers can inject malicious code into virtual environments by substituting seed wheels when custom indexes are configured, requiring an upgrade to fix.","user_interaction":"required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"}],"description":"virtualenv is a tool for creating isolated virtual python environments. Prior to 21.7.12, download_wheel() accepts pip and setuptools seed wheels fetched for periodic updates or the --download option without checking their bytes against an authoritative digest equivalent to the embedded wheels' BUNDLE_SHA256 verification. A compromised index, stale mirror, or intercepted TLS connection can substitute a different wheel under the requested distribution, version, and filename, after which virtualenv caches and seeds the attacker-controlled wheel into subsequently created environments. The verification applies to the default PyPI path and is intentionally skipped when PIP_INDEX_URL, PIP_EXTRA_INDEX_URL, or PIP_INDEX configures a custom index that may legitimately publish rebuilt wheels.
