CVE-2025-49004 | Hijacking Caido instance during the initial setup via DNS Rebinding to achieve RCE

Caido is a web security auditing toolkit. Prior to version 0.48.0, due to the lack of protection for DNS rebinding, Caido can be loaded on an attacker-controlled domain. This allows a malicious website to hijack the authentication flow of Caido and achieve code execution. A malicious website loaded in the browser can hijack the locally running Caido instance and achieve remote command execution during the initial setup. Even if the Caido instance is already configured, an attacker can initiate the authentication flow by performing DNS rebinding. In this case, the victim needs to authorize the request on dashboard.caido.io. Users should upgrade to version 0.48.0 to receive a patch.

7.5 3.1 HIGH
CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
