How do I detect CVE-2026-120448 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-120448 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2026-120448 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-120448 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

DoraCMS through 3.1.0 contains a mass assignment vulnerability in the PUT /api/v1/user/api-keys/:id endpoint that allows authenticated low-privileged users to rebind their API key to another user's account. Attackers can set the userId field on their own key to a victim's id, then act as that victim to modify profiles and publish or delete content.
