CVE-2026-65325: CWE-295 Improper Certificate Validation in Apache Software Foundation Apache Traffic Server
Apache Traffic Server reuses multiplexed HTTP/2 origin connections without verifying the server certificate covers the new request hostname. This issue affects Apache Traffic Server: from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3. Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue.
AI Analysis
Technical Summary
CVE-2026-65325 is a vulnerability in Apache Traffic Server where multiplexed HTTP/2 origin connections are reused without proper verification that the server certificate covers the hostname of the new request. This improper certificate validation (CWE-295) could lead to potential security risks related to trusting a reused connection with an incorrect or mismatched certificate. The affected versions are from 9.0.0 through 9.2.14 and 10.0.0 through 10.1.3. Upgrading to 9.2.15 or 10.1.4 addresses this issue.
Potential Impact
The vulnerability impacts confidentiality and integrity to a limited extent, as indicated by the CVSS vector (C:L/I:L/A:N). An attacker could potentially exploit this flaw to perform man-in-the-middle attacks or impersonate a server by leveraging reused connections with invalid certificates. However, the attack complexity is high and no privileges or user interaction are required. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade Apache Traffic Server to version 9.2.15 or 10.1.4, where this certificate validation issue has been fixed. No other mitigations are specified or required.
