CVE-2026-71614

A security flaw was discovered in GPAC 26.08-DEV affecting the function gf_inline_get_proto_lib in src/compositor/mpeg4_inline.c (Proto Link Handler component). The manipulation results in a use-after-free condition, and the attack requires local access. The exploit has been publicly released and may be used for attacks.

A vulnerability was determined in GPAC 26.08-DEV affecting the function gf_node_deactivate_ex in src/scenegraph/base_scenegraph.c (MP4Box component). Executing a manipulation can lead to a use-after-free condition, and the attack requires local access. The exploit has been publicly disclosed and may be utilized.

A vulnerability was found in GPAC 26.03-DEV in the vobsub_read_idx function of the MP4Box component. Manipulating the num_langs argument can cause an out-of-bounds read. The attack requires local access and the exploit has been publicly disclosed.

A stack overflow in the dump_ttxt_sample function of GPAC v2.4.0 allows attackers to cause a Denial of Service (DoS) via a crafted packet.

An out-of-bounds read in the GSF demuxer filter component of GPAC v2.4.0 allows attackers to cause a Denial of Service (DoS) via a crafted .gsf file.

A buffer overflow in the vobsub_get_subpic_duration() function of GPAC v2.4.0 allows attackers to cause a Denial of Service (DoS) via a crafted packet.

GPAC v2.4.0 was found to contain an out-of-bounds read in the oggdmx_parse_tags function. The issue occurs during processing of OGG data.

NULL pointer dereference vulnerability in the GitHub repository gpac/gpac prior to 1.1.0. It may cause an application crash when processing crafted data.

GPAC through 26.07.0 contains a type confusion vulnerability in drawable_get_aspect_2d_mpeg4() and TraverseShape() that cast a Shape's appearance node to M_Appearance without checking its node tag. An attacker can supply a crafted XMT file placing another node type, such as Conditional, in the appearance field, triggering an invalid memory read and crashing MP4Box.

GPAC through 26.07.0 contains a type confusion vulnerability in gf_sg_command_apply() in src/scenegraph/commands.c that fails to verify BIFS field-replace command types match target node fields. An attacker can supply a crafted XMT file opened with MP4Box, such as via chapter import, causing gf_sg_vrml_field_clone() to memcpy from invalid pointers and crash.
