Sep 17, 2026OpenDDS is an open source C++ implementation of the Object Management Group (OMG) Data Distribution Service (DDS).CVE-2026-52836 · Other software · OpenDDS · reported by GitHubHigh 8.7
OpenDDS is an open source C++ implementation of the Object Management Group (OMG) Data Distribution Service (DDS). Prior to 3.34.0, a network attacker can crash a reachable OpenDDS participant by sending a malformed RTPS UDP submessage whose crafted length or sequence-number state causes dds/DCPS/transport/rtps_udp/RtpsUdpReceiveStrategy.cpp in RtpsUdpReceiveStrategy::handle_input() to advance ACE_Message_Block::rd_ptr() beyond valid data. The parser can then call dds/DCPS/transport/rtps_udp/RtpsSampleHeader.cpp in RtpsSampleHeader::init(), which dereferences the invalid read pointer without first validating it against wr_ptr() or ensuring that a complete submessage header remains. The resulting SIGSEGV occurs in the receive thread, terminates the DDS process, and destroys the DDS entities hosted by that participant. No authentication, prior protocol state, or victim interaction is required. This issue is fixed in version 3.34.0.

Jan 9, 2025An attacker can arbitrarily craft malicious DDS Participants (or ROS 2 Nodes) with valid certificates to compromise and get full control of the attacked secure CVE-2023-24012 · Other software · OpenDDS · reported by cve-coordination@incibe.esHigh 8.2
An attacker can arbitrarily craft malicious DDS Participants (or ROS 2 Nodes) with valid certificates to compromise and get full control of the attacked secure DDS databus system by exploiting vulnerable attributes in the configuration of PKCS#7 certificate’s validation. This is caused by a non-compliant implementation of permission document verification used by some DDS vendors. Specifically, an improper use of the OpenSSL PKCS7_verify function used to validate S/MIME signatures.

Jul 21, 2023OpenDDS is an open source C++ implementation of the Object Management Group (OMG) Data Distribution Service (DDS).CVE-2023-37915 · Other software · OpenDDS · reported by GitHubHigh 7.5
OpenDDS is an open source C++ implementation of the Object Management Group (OMG) Data Distribution Service (DDS). OpenDDS crashes while parsing a malformed `PID_PROPERTY_LIST` in a DATA submessage during participant discovery. Attackers can remotely crash OpenDDS processes by sending a DATA submessage containing the malformed parameter to the known multicast port. This issue has been addressed in version 3.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
