CVE-2026-108861
Odoo MCP 1.0.0 through 1.3.2 contains an information disclosure vulnerability that allows MCP clients to bypass the field-level ACL by invoking the execute_method tool.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
