CVE-2025-1795 (GCVE-0-2025-1795)

Vulnerability from cvelistv5 – Published: 2025-02-28 18:59 – Updated: 2025-12-01 19:01
VLAI?
Summary
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.
Severity ?
2.3 (Low)
