Hi, The following vulnerability was published for pypy3. CVE-2026-8328[0]: | The ftpcp() function in Lib/ftplib.py was not updated when | CVE-2021-4189 was fixed. While makepasv() was patched to replace | server-supplied PASV host addresses with the actual peer address | (getpeername()[0]), ftpcp() still calls parse227() directly and | passes the raw attacker-controllable IP address and port to | target.sendport(). This patch is related to CVE-2021-4189. https://mail.python.org/archives/list/[email protected]/thread/ITF2BAPBQEPYK3LDMPRSY435JGNHYNDP/ https://github.com/python/cpython/pull/149648 https://github.com/python/cpython/commit/eac4fe3b2c77693790a5ef7dfab127c1fee81bf9 (main branch) If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
