What is CVE-2026-85452?
MOOS ui-moos through 50b9c6c contains a buffer overflow vulnerability in ScopeTabPane.cpp and ScopeGrid.cpp where client and variable names are formatted into fixed 1024-byte buffers using sprintf without length validation. Attackers can supply arbitrarily long MOOS identifiers that overflow the buffers when an operator selects process list entries or pokes variables, enabling code execution.
CVSS Score Explained
CVSS 8.7 is High severity. Exploitation is likely straightforward and the impact is significant — data loss, privilege escalation, or remote code execution are common outcomes. Patch as soon as possible.

- CVE-2026-85450MOOS core-moos through 10.4.0 contains a denial of service vulnerability in the MOOSDB HTTP server that creates unbounded connections and threads without limits. Attackers can open many connections and send endless header data to exhaust server threads and memory, causing service unavailability.8.7
- CVE-2026-85451MOOS core-moos through 10.4.0 contains a remote process termination vulnerability in the SuicidalSleeper component that uses a hard-coded passphrase for multicast command authorization. Any multicast-reachable peer can enumerate MOOS processes and send termination commands to trigger process shutdown by exploiting the default multicast group and port with the known passphrase.7.1
- CVE-2026-85453MOOS core-moos through 10.4.0 fails to escape database contents when rendering MOOSDB HTTP pages, allowing attackers to inject malicious scripts. Any MOOS publisher can set variable values containing script payloads that execute in the browser of operators viewing the web interface.5.3
- CVE-2026-85454MOOS core-moos through 10.4.0 contains a buffer overflow vulnerability in CMOOSSerialPort::GetTelegram() that writes a NUL terminator one byte past the serial telegram stack buffer. Attackers controlling the serial line can send a full-length telegram to trigger the off-by-one write, corrupting the stack and potentially enabling code execution.5.2
- CVE-2026-85455MOOS core-moos through 10.4.0 contains a buffer over-read vulnerability in CMOOSCommPkt where a four-byte packet triggers out-of-bounds memory access during deserialization. Attackers can open a TCP connection to the MOOSDB port and send a crafted short packet to read memory before authentication.8.8
- CVE-2026-85456MOOS-IvP through 24.8.1 fails to properly validate variable names extracted from alog files in the SplitHandler, allowing attackers to write files outside the split directory. Attackers can supply crafted alog files with backslash sequences in variable names to escape the output directory and append to arbitrary files on Windows systems.6.8
