Security readout for executives and security teams
Plain-English summary
CVE-2026-1416 is a denial-of-service flaw in GPAC, a multimedia framework, affecting versions up to 2.4.0. A local user can trigger a null pointer dereference in MP4Box movie information dumping. Business impact is likely limited to crashes or interrupted media-processing workflows, not data theft or remote compromise based on provided sources.
Executive priority
Handle as a routine patching item unless GPAC is used in shared media-processing environments. The issue is publicly disclosed, but impact is limited and local-only in the supplied evidence. Prioritize validation and patch planning over emergency response.
Technical view
The flaw is in DumpMovieInfo in applications/mp4box/filedump.c. Manipulated input or invocation can cause a null pointer dereference, mapped to CWE-476 and CWE-404. CVSS 4.0 is 4.8 with local attack vector, low complexity, low privileges, no user interaction, and low availability impact only.
Likely exposure
Exposure is most relevant where GPAC or MP4Box is installed on workstations, build systems, media pipelines, or services that allow local authenticated users to run GPAC tools. The provided sources list GPAC 2.0 through 2.4.0 as affected.
Exploitation context
Sources state a public exploit exists, but CISA KEV status is false and no cited source confirms active exploitation. The attack is local and requires low privileges. Expected impact is application crash or limited availability disruption, not confidentiality or integrity compromise.
Researcher notes
The source bundle attributes the fix to commit d45c264c20addf0c1cc05124ede33f8ffa800e68. Evidence does not confirm an official GPAC release containing the fix. Avoid overstating exploitation: public proof exists, but active exploitation is not shown by KEV or cited sources.
Mitigation direction
- Identify GPAC and MP4Box installations and versions across endpoints and media-processing systems.
- Prioritize systems where untrusted local users can access GPAC tools.
- Apply the referenced patch commit if appropriate for your build process.
- Check GPAC upstream guidance for an official fixed release or backport status.
- Restrict local access to GPAC tooling where patching is delayed.
Validation and detection
- Confirm whether installed GPAC versions are 2.0, 2.1, 2.2, 2.3, or 2.4.0.
- Review package manifests, container images, and build dependencies for GPAC or MP4Box.
- Verify whether the referenced patch commit is present in your deployed source or package.
- Monitor crash reports involving MP4Box movie information dumping paths.
- Track GPAC issue 3427 and vendor advisories for fix confirmation.
