Technical Analysis
CVE-2026-85455 describes a buffer over-read vulnerability in the MOOS core-moos software up to version 10.4.0. The flaw exists in the CMOOSCommPkt deserialization logic, where a four-byte packet causes out-of-bounds memory access. This vulnerability can be exploited remotely without authentication by sending a crafted short packet over a TCP connection to the MOOSDB port, potentially allowing an attacker to read memory contents.
Potential Impact
An unauthenticated remote attacker can trigger out-of-bounds memory reads by sending a crafted packet to the MOOSDB port. This may lead to disclosure of sensitive memory contents. The CVSS 4.0 base score is 8.8 (high severity), reflecting the network attack vector, no required privileges or user interaction, and high impact on confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented. Until a patch is available, consider restricting access to the MOOSDB port to trusted hosts only.
