CVE-2025-58136: Apache Traffic Server

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

A bug in POST request handling causes a crash under a certain condition. This issue affects Apache Traffic Server: from 10.0.0 through 10.1.1, from 9.0.0 through 9.2.12. Users are recommended to upgrade to version 10.1.2 or 9.2.13, which fix the issue. A workaround for older versions is to set proxy.config.http.request_buffer_enabled to 0 (the default value is 0).

Affected products

• Apache Traffic Server: from 9.0.0, before 9.2.13 (fixed in 9.2.13); from 10.0.0, before 10.1.2 (fixed in 10.1.2)
