CVE-2026-58617 [CRITICAL] Patch Tuesday - July 2026
Microsoft is publishing 622 vulnerabilities on July 2026 Patch Tuesday , including a record-breaking 416 Windows vulnerabilities. Microsoft is aware of exploitation in the wild for two of the vulnerabilities published today, both of which are listed on CISA KEV, as well as public disclosure for one other. As usual, browser vulns are not included in the Patch Tuesday count above. Rapid7 noted last month that Microsoft no longer enumerates Chromium CVEs in the Security Update Guide. However, Microsoft has now taken the pursuit of minimalism much further, since today’s Security Update Guide no longer lists out even Microsoft vulnerabilities! Instead, we now receive a summary table of vulnerability counts by product family, as well as a new slimline “Notable CVEs” section. All of this only ser

This patch Tuesday includes a staggering 622 vulnerabilities, not including another 427 vulnerabilities in Chromium, affecting Microsoft's Edge browser. 62 of the vulnerabilities are rated critical. One was disclosed before today, and two have already been exploited.
Given the large number of vulnerabilities, it is difficult to point out "noteworthy" issues.
Already exploited vulnerabilities:
CVE-2026-56155 : Active Directory Federation Services Elevation of Privilege Vulnerability. This is an important (not critical) vulnerablity.
