The Web add-on's HTTP server dereferences and releases an uninitialized pointer when it detects a `Content-Length` underflow while processing a `PUT` request. The condition is reachable by an unauthenticated remote client with a single malformed request.

The X.509 parser in NetX Secure accepts an RSA public key of any size, but every signature-verification path decrypts into fixed-size buffers dimensioned for the `NX_CRYPTO_MAX_RSA_MODULUS_SIZE` default of 4096 bits. A certificate carrying a larger modulus drives an out-of-bounds write past a file-scope static during ordinary certificate-chain verification. It is reachable pre-authentication. The issuer used for the crypto operation is looked up in the remote, peer-supplied store before the trusted store, so the attacker supplies the oversized key themselves as an intermediate in the chain they present. It triggers on a TLS or DTLS client verifying a malicious server's chain, and on a server performing client-certificate authentication.

The Web add-on's HTTP server searches the entire request packet for header fields instead of stopping at the end of the header section. A header field name placed in the request body is therefore reported to the server as though it were a header, which lets a client control request framing decisions it should not be able to reach.

The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to `0xFFFFFFFF`, which makes the bounds check that follows vacuous and sends the parser reading past the session packet buffer. The trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication.

A missing bounds check in the TLS 1.3 Certificate-message parser of NetX Secure lets a malicious TLS 1.3 server trigger an unsigned-integer underflow and a subsequent heap out-of-bounds read in any peer that processes a remote Certificate message. It is reachable pre-authentication, during the normal handshake, before certificate verification completes.

Out-of-bounds write via the TLS 1.3 handshake message cache in NetX Duo in Eclipse ThreadX NetX Duo 6.5.1.202602 allows a handshake message larger than the cache writes past it and on into the rest of the session control block, which holds pointers. A malicious or compromised server can make a TLS 1.3 client produce such a message before certificate authentication completes, so no server certificate is needed to reach it.

Jun 19, 2026The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this uCVE-2026-11576 · Other software · Eclipse Foundation · reported by emo@eclipse.orgHigh 7.5
The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple error branches jump to the shared cleanup label before any file open operation has occurred, causing fx_file_close() to operate on an uninitialized file handle, leading to undefined behavior, double-close issues, or memory corruption.

A denial-of-service vulnerability exists in the NetX IPv6 component functionality of Eclipse ThreadX NetX Duo. A specially crafted network packet of "Packet Too Big" with more than 15 different source address can lead to denial of service. An attacker can send a malicious packet to trigger 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.
