CVE-2026-73610
SiYuan before v3.7.4 contains an information disclosure vulnerability in the local storage filter that returns the administrator's entire storage map with only three keys sanitized.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
