Apache HTTP Server 2.4.49: a path-traversal fix that needed a second fix
CVE-2021-41773 was a path traversal in Apache httpd 2.4.49 that could leak files and, with CGI enabled, reach RCE. The 2.4.50 fix was incomplete, so CVE-2021-42013 followed days later. Two CVEs, one bug, a textbook patch-the-patch.

Mitel MiCollab keeps shipping the same path-traversal bug class
watchTowr published a working unauth file-read chain on December 5, 2024 with one of the two CVEs still a 0-day. The pattern across NPM, ReconcileWizard, and AWV is structural, and operators tolerate it because UC is the most upgrade-averse tier in the enterprise.

TeamCity's path traversal took two years to reach KEV. That's a long time to leave a CI server exposed.
CVE-2024-27199, a path traversal in JetBrains TeamCity On-Premises, was patched in March 2024 and exploited by BianLian ransomware within days. CISA added it to KEV in April 2026 with a May 4 federal deadline. If you're still below 2023.11.4, this is two years overdue.
