expat: Expat: XML Injection via Malformed UTF-16 Input

A flaw was found in Expat. This vulnerability allows a remote attacker to send specially crafted UTF-16 encoded XML data. Due to improper validation of surrogate characters, the parser can be tricked into accepting malformed sequences, which can hide legitimate markup characters. This could enabl...

CVE-2026-100505

Ghidra versions 11.2 through 12.1.4 are susceptible to a heap out-of-bounds read vulnerability in the StringManager::getCodepoint function. The root cause is a failure to validate the remaining buffer length when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters. An attacker can exploit thi...
