Vulnerability in eprosima Fast DDS (CVE-2026-22591)
Summary
Vulnerability in eprosima Fast DDS (CVE-2026-22591). Risk of unauthorized operations or information disclosure. Exploitable via DATA.
Original description
The description as published by the source.
eprosima Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). Prior to versions 2.6.12, 2.14.6, 3.2.4, and 3.4.3, Fast DDS’s implementation of SQL‑based content filtering (DDSSQLFilter) allows any participant in a DDS domain to remotely crash other Fast DDS participants by sending a single crafted SEDP DATA submessage whose PID_CONTENT_FILTER_PROPERTY.filterExpression contains a deeply nested filter expression. Versions 2.6.12, 2.14.6, 3.2.4, and 3.4.3 fix the issue.
