CVE-2026-102511

Improper Verification of Source of a Communication Channel in the ADS discovery of the Go implementation of Apache PLC4X PLC4Go allows an attacker able to send UDP datagrams to the discovering host to redirect subsequent connections to an arbitrary, attacker-chosen address. The discovery result's...

CVE-2026-102508

Improper Verification of Cryptographic Signature and Improper Certificate Validation in the OPC UA driver of Apache PLC4X PLC4J allows an attacker in a network position between client and server to impersonate the OPC UA server and to read, forge or modify secure-channel traffic, including user...

Improper Verification of Source of a Communication Channel in the ADS discovery of the Go implementation of Apache PLC4X PLC4Go allows an attacker able to send UDP datagrams to the discovering host to redirect subsequent connections to an arbitrary, attacker-chosen address. The discovery result's...

CVE-2026-102511

Apache PLC4X is vulnerable to an improper verification of source during ADS discovery. In the PLC4Go implementation, an attacker can send spoofed UDP datagrams to force the host to derive connection addresses from the response body's AmsNetId instead of the actual source address. This allows an a...

CVE-2026-102511 Apache PLC4X, Apache PLC4X, Apache PLC4X, Apache PLC4X: ADS discovery accepts spoofed responses and derives the connection target from them

Improper Verification of Source of a Communication Channel in the ADS discovery of the Go implementation of Apache PLC4X PLC4Go allows an attacker able to send UDP datagrams to the discovering host to redirect subsequent connections to an arbitrary, attacker-chosen address. The discovery result's...

CVE-2026-102509

The Apache PLC4X (PLC4J) Java implementation is vulnerable to pre-authentication resource exhaustion in the OPC UA driver and the Java SPI parser . The root causes include memory allocation with excessive size values, allocation of resources without limits, and uncontrolled recursion. Specificall...

EUVD-2026-89678

Memory Allocation with Excessive Size Value, Allocation of Resources Without Limits, and Uncontrolled Recursion in the Java implementation of Apache PLC4X PLC4J allow a malicious or impersonated device to exhaust the memory or stack of the client application, causing a denial of service. In the O...

CVE-2026-102508

The Apache PLC4X (PLC4J) OPC UA driver is vulnerable to integrity bypass , unverifiable server certificates , and silent downgrades in versions 0.9.0 through 0.13.1 . The root cause involves improper cryptographic signature verification and lack of trust anchors: versions 0.9.0–0.11.0 fail to enf...
