CVE-2026-11873
MediumCVSS 6.5Exploitation Probability (EPSS)
Low risk40th percentile - higher than 40% of all known CVEs
Summary
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.
Risk Assessment
An attacker can cause excessive log growth and disk I/O, potentially leading to disk exhaustion and system slowdown.
Recommendation
Restrict access to the /ca/rest/certrequests endpoint to authenticated clients only, and configure log size limits and rotation to prevent excessive growth.
