CVE-2026-85425Network attack vector

Remote command execution via shell-interpreted SAY_MOOS text

Published Sep 3, 2026 · Updated Sep 4, 2026

Command injection in MOOS-IvP iSay 24.8.1 and earlier allows remote attackers to execute commands through crafted SAY_MOOS messages. Sayer::sayUtterance builds a shell command from verbatim utterance text and passes it to system(), so quote-closing or command-substitution syntax is interpreted by the shell. Any unauthenticated client able to reach MOOSDB can execute commands with the iSay process user's privileges.
