What is CVE-2026-120448?

DoraCMS versions up to 3.1.0 are susceptible to a mass assignment vulnerability that can be exploited by authenticated low-privileged users. This vulnerability exists in the PUT /api/v1/user/api-keys/:id endpoint, which allows attackers to rebind their API key to a victim's account. By manipulating the userId field, an attacker can impersonate the victim, gaining unauthorized access to modify their profile and potentially publish or delete content on their behalf. This highlights a critical area of concern for user security and data protection within the platform.

Affected Version(s)

DoraCMS 0 <= 3.1.0

Exploit Proof of Concept (PoC)
