CVE-2026-76561 — Pki-core: dogtag/pki: certprofile-import allows code execution via unsanitized profile content (externalprocessconstraint)

A flaw was found in Dogtag PKI, as used by FreeIPA's certificate authority component. The certificate profile import functionality does not fully validate uploaded profile content beyond the profile ID. An authenticated user with CA Administrator privileges can exploit Dogtag's ExternalProcessConstraint mechanism to execute arbitrary commands with attacker-controlled environment variables, achieving code execution as the pkiuser account.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.4% (30-day exploitation probability)+5
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Red Hat Red Hat Certificate System 9, Red Hat Red Hat Enterprise Linux 10, Red Hat Red Hat Enterprise Linux 7…).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

  • Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
  • Look for parameters with command/query metacharacters and unexpected child processes of the service.

What should defenders know first?

CVE-2026-76561 is "Pki-core: dogtag/pki: certprofile-import allows code execution via unsanitized profile content (externalprocessconstraint)", rated High. It affects Red Hat Certificate System 9 (Red Hat); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.2 describes technical severity. EPSS 0.43% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
