0 A vulnerability in libexpat's Unicode processing mishandles low surrogate pairs, causing an out-of-bounds read and an infinite loop. This flaw can be triggered by specially crafted XML input, leading to denial of service (DoS) through high CPU usage and resource exhaustion. The issue affects certain versions of libexpat before 2.8.3-0.1.hum1 and 1.59.02-4.oe2403sp4. A patch is available to address this vulnerability.

CVE-2026-66046 is a denial of service vulnerability in libexpat through version 2.8.3. It arises from inefficient algorithmic complexity in the storeAtts() function of xmlparse.c, where processing attributes with non-normalized values causes quadratic time complexity. A remote unauthenticated attacker can exploit this by sending a crafted XML document to cause excessive CPU usage and denial of service without needing authentication or special parser options.

libexpat before 2.8.3 has an out-of-bounds read and resultant infinite loop because low surrogates are treated the same as high surrogates during Unicode processing in the *_toUtf16 functions. Join the discussion | CVE Database V5 | 08/10/2026, 03:28:04 UTC Added: 08/10/2026, 03:56:43 UTC |
