Critical CVSS 9.8

CVE-2026-58177

Apache Traffic Server

The Apache Traffic Server Cripts framework has out-of-bounds writes, path traversal, and use-after-free errors. This issue affects Apache Traffic Server: from 10.0.0 through 10.1.3. Users are recommended to upgrade to version 10.1.4, which fix the issue.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Weakness
An out-of-bounds write corrupts neighbouring memory and often enables code execution.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doPatch without waiting for the next scheduled cycle. Start with the instances exposed to the internet.
