How to prioritise siyuan-note patching
This order follows the data Threadlinqs holds for siyuan-note, not a generic severity checklist:
- No siyuan-note CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are CVE-2026-66012 (0.4%), CVE-2026-73046 (0.4%), CVE-2026-73043 (0.4%).
- 9 CVEs score Critical and 2 High on CVSS v3 (maximum 10, average 8.7); sequence these after KEV and high-EPSS items.
- 1 CVE has a public exploit or proof of concept recorded, which shortens the time from disclosure to attack.
About this data
Vendor attribution comes from the CNA and CPE product records of each CVE, folded to one vendor name; CVSS, EPSS and KEV status are read from the Threadlinqs CVE catalog; campaign and actor links come from tracked threat records. Counts reflect the data as of 2026-10-05 and refresh daily.
