CVE-2026-11873

6.5 mediumEPSS 0.5%

Medium (6.5). EPSS 0.5% chance of exploitation in the next 30 days.

An Apache-proxied Dogtag CA REST endpoint exposed by IdM (POST /ca/rest/certrequests) returns HTTP 500 with internal Java stack traces for unauthenticated malformed requests. The same unauthenticated error path emits large multi-line stack traces into the CA debug log, creating a log-amplification resource exhaustion vector (disk growth and I/O contention) without requiring authentication.
