Who should care

Organizations running HPX 1.11.0 or earlier in production environments, particularly those exposing HPX services to untrusted networks or processing serialized data from external sources.

Technical summary

CVE-2025-60889 is a critical insecure deserialization vulnerability (CWE-502) in StellarGroup HPX 1.11.0 and earlier. The vulnerability allows attackers to execute arbitrary code through crafted serialized input without authentication. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) indicates network-based exploitation with low attack complexity, no privileges required, no user interaction, and high impact to confidentiality, integrity, and availability. Affected CPE: cpe:2.3:a:stellar-group:hpx:*:*:*:*:*:*:*:* versions up to 1.11.0.

Defensive priority

critical

Recommended defensive actions

  • Upgrade HPX to a version newer than 1.11.0 when available from the vendor.
  • Implement strict input validation and sanitization for all serialized data inputs.
  • Apply principle of least privilege to HPX service accounts and network segments.
  • Monitor for anomalous deserialization activity and unexpected process execution.
  • Review application logs for suspicious serialized object patterns.

Evidence notes

The vulnerability affects HPX versions up to and including 1.11.0 per NVD CPE criteria. The CWE-502 classification confirms insecure deserialization as the root cause. Multiple sources reference a third-party exploit advisory.
