DescriptionCVE.org

A vulnerability was identified in GPAC 26.08-DEV. The impacted element is the function gf_sg_command_del of the file src/scenegraph/commands.c of the component BIFS Handler. The manipulation leads to use after free. The attack needs to be performed locally. The exploit is publicly available and might be used. Upgrading to version abi-16.24 is sufficient to resolve this issue. The identifier of the patch is e34f4ba349d55cd1849f0bcf4cf46552732e2db7. It is suggested to upgrade the affected component.

AnalysisAI

Opening a specially crafted BIFS or LASeR scene file in GPAC 26.08-DEV can trigger a use-after-free in the scene-graph command handler, crashing the application. Only local exploitation is possible: the victim must load attacker-supplied media in a vulnerable pre-abi-16.24 build, there is no network-reachable trigger, and impact is limited to availability (denial of service) with no confidentiality or integrity effect. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an attacker-controlled BIFS (or LASeR) scene file to be opened and processed locally by GPAC 26.08-DEV; the use-after-free is reached through gf_sg_command_apply/gf_sg_command_del when a scene command references a freed node. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a low-priority, low-real-risk issue despite a publicly available PoC. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
