CWE-94Published: July 28, 2023· Updated: Jun 17, 2026
Official Description
FFmpeg 0.7.0 and below was discovered to contain a code injection vulnerability in the component net.bramp.ffmpeg.FFmpeg.<constructor>. This vulnerability is exploited via passing an unchecked argument. NOTE: this is disputed by multiple third parties because there are no realistic use cases in which FFmpeg.java uses untrusted input for the path of the executable file.
Risk Analysis
This vulnerability involves a code injection flaw in the FFmpeg CLI wrapper. While it carries a critical CVSS score of 9.8, third parties have disputed the risk, noting that there are no realistic scenarios where untrusted input is used for the executable path.
There is no known public exploit for this vulnerability, and it is not listed in CISA's KEV catalog.
Users should ensure they are not passing untrusted input to the affected component and update to a version beyond 0.7.0 if applicable.
Technical Analysis
CVE-2023-39018 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
