This vulnerability was discovered and disclosed on July 29, 2025. The issue affects the Memos application, a self-hosted knowledge management and note-taking platform (NVD, Miggo).
Technical details
The vulnerability is tracked as CVE-2025-50738 and has received a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H.
