Comment 1 Ben Beasley 2026-01-10 15:20:54 UTC
While uv does bundle (and document bundling of) a portion of virtualenv, this includes only activation scripts[1]. Based on the CVE report[2] and upstream advisory[3], and the linked fix[4], the vulnerability is in parts of the virtualenv package other than the activation scripts. Therefore, uv is not affected.
