{"id":"BIT-python-min-2025-1795","summary":"Mishandling of comma during folding and unicode-encoding of email headers","details":"During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by some mail servers.","aliases":["BIT-libpython-2025-1795","BIT-python-2025-1795","CVE-2025-1795","PSF-2025-3"],"modified":"2025-12-04T12:23:00.972570Z","published":"2025-04-14T11:35:08.147Z","database_specific":{"cpes":["cpe:2.3:a:python:python:*:*:*:*:*:*:*:*"],"severity":"Low"},"references":[{"type":"WEB","url":"https://github.com/python/cpython/commit/09fab93c3d857496c0bd162797fab816c311ee48"},{"type":"WEB","url":"https://github.com/python/cpython/commit/70754d21c288535e86070ca7a6e90dcb670b8593"},{"type":"WEB","url":"https://github.com/python/cpython/commit/9148b77e0af91cdacaa7fe3dfac09635c3fe9a74"},{"type":"WEB","url":"https://github.com/python/cpython/issues/100884"},{"type":"WEB","url":"https://github.com/python/cpython/pull/100885"},{"type":"WEB","url":"https://github.com/python/cpython/pull/119099"},{"type":"WEB","url":"https://mail.python.org/archives/list/security-announce@python.org/thread/MB62IZMEC3UM6SGHP5LET5JX2Y7H4ZUR/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1795"},{"type":"WEB","url":"https://github.com/python/cpython/commit/a4ef689ce670684ec132204b1cd03720c8e0a03d"},{"type":"WEB","url":"https://github.com/python/cpython/commit/d4df3c55e4c5513947f907f24766b34d2ae8c090"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00013.html"}],"affected":[{"package":{"name":"python-min","ecosystem":"Bitnami","purl":"pkg:bitnami/python-min"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.9.23"},{"introduced":"3.10.0"},{"fixed":"3.10.17"},{"introduced":"3.11.0"},{"fixed":"3.11.11"},{"introduced":"3.12.0"},{"fixed":"3.12.8"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/python-min/BIT-python-min-2025-1795.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.7.3"}
