Severity: low
Affected versions:
- Apache Tomcat 9.0.47 through 9.0.122
Description:
Time-of-check time-of-use (TOCTOU) race condition vulnerability in
Apache Tomcat when creating unix domain sockets for the APR/Native
connector allows an unauthorised local user to access the unix domain
socket. The fix for CVE-2026-65183 only addressed the NIO connector. It
did not address the same issue in the APR/Native connector.
This issue affects Apache Tomcat: from 9.0.47 through 9.0.122.
Users are recommended to upgrade to version 9.0.123, which fixes the issue.
