> As of 2026-10-10, Threadlinqs tracks 7 Go standard library CVEs, 0 in the CISA Known Exploited Vulnerabilities catalog, linked to 0 tracked threat campaigns.

**Data as of:** 2026-10-10

## Exploitation timeline

Threadlinqs has recorded 7 Go standard library CVEs published between 2026-10-15 and 2026-10-15. The busiest month was 2026-10 (7 new CVEs). None of them is listed in CISA KEV yet.

## Most exploited vulnerabilities

Ranked with CISA KEV listings first, then EPSS exploit probability, then CVSS score. Showing 7 of 7 tracked Go standard library CVEs.

## Threat activity

No tracked threat campaign references Go standard library products or CVEs yet. Vulnerability records are still monitored for exploitation and linked as campaigns are ingested.

## How to prioritise Go standard library patching

This order follows the data Threadlinqs holds for Go standard library, not a generic severity checklist:

- No Go standard library CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-78669](https://intel.threadlinqs.com/cve/CVE-2026-78669) (0.2%), [CVE-2026-94439](https://intel.threadlinqs.com/cve/CVE-2026-94439) (0.2%), [CVE-2026-94440](https://intel.threadlinqs.com/cve/CVE-2026-94440) (0.2%).
- 0 CVEs score Critical and 4 High on CVSS v3 (maximum 7.5, average 7.5); sequence these after KEV and high-EPSS items.

## 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 2026-10-10 and refresh daily.
