Description
CVE-2025-71469 is a type confusion vulnerability in GPAC versions before 26.02.0. It occurs in the ctxload_process() function where non-object descriptors are passed to ODS_SetupOD() without proper tag verification. An attacker can exploit this by crafting a malicious XMT file containing a URL-bearing descriptor, leading to a crash in MP4Box or other GPAC-based applications, resulting in denial of service.
