Summary
Stonewuu's ai-fusion-video software contains an insecure direct object reference flaw that lets a logged-in user reach other users' projects, assets, and scripts by guessing sequential object IDs on its API. An attacker can read, overwrite, or cascade-delete that data and add themselves as a project member, and can reach the flaw remotely over the network with low-privilege login and no user action.
Read the original description
Stonewuu ai-fusion-video before 1.3.0 contains an insecure direct object reference vulnerability that allows authenticated users to access other users' projects by supplying unscoped object ids. Attackers can enumerate auto-increment ids on /api/project, /api/asset and /api/script handlers to read, overwrite, cascade-delete data, and add themselves as project members.

Questions about CVE-2026-121940
Is CVE-2026-121940 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. CISA's SSVC assessment notes a proof of concept exists. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The app does not check that a logged-in user owns the projects, assets, child assets and scripts they request. Any signed-in user can therefore read, change or delete other users' or teams' data, and add themselves as members of a project.Source: vulncheck.com, hackmd.io, github.com
Which versions are affected by CVE-2026-121940?
ai-fusion-video: before 1.3.0.Source: cve.now feed data
Am I affected, and how do I check?
Versions before 1.3.0 are affected; v1.2.0 is confirmed, and earlier released tags are likely affected too. To check yours, look at the version of ai-fusion-video you have deployed or the release tag you built from.Source: vulncheck.com, hackmd.io, github.com
How do I fix CVE-2026-121940?
Upgrade to ai-fusion-video 1.3.0 or later, which contains the fix. No workaround is listed in the facts.Source: vulncheck.com, hackmd.io, github.com
