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. This issue is fixed in version 21.7.12.

    (CVE-2026-102930)

    virtualenv is a tool for creating isolated virtual python environments. Prior to 21.7.11, PyEnvCfg.write()     writes prompt values verbatim to the line-oriented pyvenv.cfg format while PyEnvCfg._read_values() parses     the file with str.splitlines() and accepts the last value for duplicate keys. An attacker who influences
    --prompt, VIRTUALENV_PROMPT, or configuration input can insert a recognized line boundary and additional     keys, including home, causing consumers to use an attacker-selected base interpreter or corrupted     environment metadata. The security impact requires prompt input from outside the operator's trust     boundary; directly supplied prompt content primarily corrupts the operator's own environment. This issue     is fixed in version 21.7.11. (CVE-2026-102938)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3295 advisory.
