Security readout for executives and security teams

Plain-English summary

MISP versions through 2.4.133 contain a server-side request forgery issue in the REST client. A user-controlled use_full_path parameter could make MISP request an arbitrary URL. Business risk depends on who can use that client and what internal network resources the MISP server can reach.

Executive priority

Treat this as a near-term hardening and upgrade item, especially if MISP is internet-accessible or used by many analysts. The source evidence does not support emergency active-exploitation handling, but SSRF can expose internal systems if network controls are weak.

Technical view

The CVE describes SSRF in MISP's REST client caused by accepting an arbitrary URL through use_full_path. The public record identifies MISP through 2.4.133 as affected and references a MISP code commit. No CVSS score, CWE, affected CPE list, or detailed fixed release is provided in the source bundle.

Likely exposure

Exposure is most likely for organizations running MISP through 2.4.133 where untrusted or lower-trust users can access the REST client functionality. Impact may increase if the MISP host can reach internal metadata services, admin panels, or private APIs.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The issue is publicly disclosed and source-referenced, but exploitability details, required privileges, and attack complexity are not provided in the bundle.

Researcher notes

Key missing details are CVSS, required privileges, fixed release mapping, and exploit observations. The commit reference is the main technical anchor. Validation should focus on version, reachable internal services from the MISP host, and whether REST client use is limited to trusted users.

Mitigation direction

  • Identify all MISP instances and confirm their running versions.
  • Review MISP guidance and the referenced commit for the corrected behavior.
  • Upgrade MISP beyond affected versions when vendor guidance confirms the fixed release.
  • Restrict REST client access to trusted administrative users only.
  • Limit outbound network access from MISP to required destinations.

Validation and detection

  • Check whether any deployed MISP instance is version 2.4.133 or earlier.
  • Review MISP roles to identify users with REST client access.
  • Inspect outbound firewall rules from the MISP server.
  • Check logs for unusual REST client requests to internal or unexpected URLs.
