Security readout for executives and security teams
Plain-English summary
CVE-2026-1417 is a local denial-of-service issue in GPAC’s MP4Box file dump code. A local user can trigger a crash through a null pointer dereference. Business impact is likely limited to systems where untrusted local users or automated media-processing jobs can invoke affected GPAC versions.
Executive priority
Treat as a targeted operational stability risk, not an enterprise-wide emergency. Prioritize remediation where GPAC processes untrusted media or runs in shared environments. Standard patch management is appropriate unless affected systems support critical production media workflows.
Technical view
The issue affects GPAC versions 2.0 through 2.4.0 in applications/mp4box/filedump.c, function dump_isom_rtp. The reported weakness is 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 required, no user interaction, and low availability impact.
Likely exposure
Exposure is most relevant on workstations, build systems, CI pipelines, or media-processing hosts running GPAC or MP4Box versions 2.0 to 2.4.0. Internet-facing exposure is not indicated by the provided sources because the attack vector is local.
Exploitation context
The source bundle states a public exploit exists and could be used. It does not show CISA KEV listing or confirmed active exploitation. Exploitation requires local access with low privileges and is expected to cause limited availability impact rather than data theft or code execution.
Researcher notes
The provided evidence identifies the vulnerable function and patch reference but does not provide an official GPAC release note in the bundle. Public proof-of-concept availability is reported, but active exploitation is not established. Validation should focus on version, patch presence, and local execution paths.
Mitigation direction
- Inventory GPAC and MP4Box installations and identify versions 2.0 through 2.4.0.
- Apply the referenced patch f96bd57c3ccdcde4335a0be28cd3e8fe296993de or vendor-recommended update.
- Restrict local access to systems that process untrusted media files.
- Avoid processing untrusted media with affected GPAC builds until remediated.
- Monitor GPAC upstream advisories for official release guidance.
Validation and detection
- Confirm installed GPAC or MP4Box version on relevant hosts.
- Check whether the referenced patch is present in the deployed source or package.
- Review media-processing workflows for untrusted local input paths.
- Verify local users and service accounts allowed to invoke GPAC tools.
- Track GitHub issue 3426 and VulDB entry 342806 for status changes.
