MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
A use-after-free flaw was found in GPAC up to f1219cde in the gf_list_count function of utils/list.c, used by the MP4Box component. The attack requires local access and a public exploit is already available. The issue is fixed in version abi-16.23 (patch 49dee5cad329cfed310c1682703df7daa47df31a).
Risk Assessment
A local attacker can trigger a use-after-free, causing a crash or potentially arbitrary code execution in the context of the process handling media files. Since the exploit is public, the risk of exploitation is high.
Recommendation
Upgrade GPAC to version abi-16.23 or apply patch 49dee5cad329cfed310c1682703df7daa47df31a. Restrict the ability of unprivileged users to run MP4Box on untrusted files.
