CVE-2025-63783

Exp

A Broken Object Level Authorization (BOLA) vulnerability was discovered in the tRPC project mutation APIs (update, delete, add/remove tag) of the Onlook web application 0.2.32. The vulnerability exists because the API fails to verify the ownership or membership of the currently authenticated user for the requested project ID. An authenticated attacker can send a malicious request containing another user's project ID to unlawfully modify, delete, or manipulate tags on that project, which can severely compromise data integrity and availability.

7.6 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/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:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
