What is CVE-2026-111810?

An issue within Apache Traffic Server versions 9.2.15, 10.1.4, and 10.2.0 allows excessive log data generation due to unthrottled logging of internal headers. When processing requests with multiple internal @ headers, the server generates a disproportionate amount of diagnostic log information, which could lead to potential log data management challenges. Users are advised to upgrade to versions 9.2.16, 10.1.5, or 10.2.1 to mitigate this issue.

Affected Version(s)

Apache Traffic Server 9.2.15
