CVE-2026-90791 Details
Description
A vulnerability was detected in GPAC up to f1219cde. This vulnerability affects the function gf_node_unregister of the file scenegraph/base_scenegraph.c of the component MP4Box. The manipulation results in use after free. The attack can be executed remotely. The exploit is now public and may be used. Upgrading to version abi-16.23 is able to resolve this issue. The patch is identified as 9eb40df4448b88d6a6ce3454657c06f47eff0b24. Upgrading the affected component is recommended.
A heap-use-after-free vulnerability has been identified in GPAC versions prior to abi-16.23, specifically within the MP4Box component. The issue arises in the 'gf_node_unregister' function, located in 'scenegraph/base_scenegraph.c'. When a malformed XMT document is processed, it can leave dangling references to prototype nodes in the scene graph. During the cleanup process, these stale references are accessed, leading to a use-after-free condition. This vulnerability can be exploited remotely, causing applications that handle XMT content to crash. Furthermore, the memory corruption could be leveraged for more severe impacts, depending on how GPAC is integrated and how the freed memory is reused.
Users are advised to upgrade to GPAC version abi-16.23 or later, where this vulnerability has been fixed.
