CVE-2026-85446 — MOOS-IvP through 24.8.1 uFldNodeComms Quadratic Processing Denial of Service

MOOS-IvP versions through 24.8.1 contain a quadratic processing vulnerability in uFldNodeComms where each new node identity creates a ledger entry and triggers all-pairs distribution work. Attackers can supply unbounded distinct node names in reports to drive the shoreside broker into quadratic processing, delaying or preventing distribution of legitimate node reports.

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 0.6% (30-day exploitation probability)+7
  • Technical severity (high)+6
  • Automatable exploitation (SSVC)+3

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.

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 (Mit Moos-ivp, Moos-ivp Moos-ivp).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. Apply the fixed version or the patch documented under Remediation.
  4. Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?

CVE-2026-85446 is "MOOS-IvP through 24.8.1 uFldNodeComms Quadratic Processing Denial of Service", rated High. It affects Moos-ivp (Mit); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.5 describes technical severity. EPSS 0.63% 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.
