CISA has added an Apache Tomcat flaw to its actively exploited vulnerability list, warning organizations that attackers are already using it in real attacks. The issue is CVE-2025-24813, a remote-code-execution flaw in Apache Tomcat that can let an attacker run code on vulnerable servers under certain conditions; the article indicates CISA added it to the Known Exploited Vulnerabilities catalog alongside Langflow and N-central bugs.
Why it matters: Organizations running Tomcat may now face real break-in risk, not just theoretical exposure. This raises the priority to patch or mitigate immediately, especially for internet-facing Java application servers.

This is related only at the product level, not the same event: the article covers a different Apache Tomcat flaw, CVE-2026-34486, that CISA newly added to KEV after exploitation attempts to plant reverse shells.

This is a separate Tomcat KEV addition but close in underlying event type: CISA warning of active exploitation of an Apache Tomcat flaw. It adds a new exploited Tomcat vulnerability, CVE-2026-34486, tied to EncryptInterceptor bypass and reported Chinese threat activity.

The tracked list includes matching stories for the Langflow and N-able flaws from this CISA KEV update, but not the Apache Tomcat flaw named in the same article, so this establishes a distinct Tomcat active-exploitation story.
