Jenkins Missing Permission Check

Description

Jenkins 2.503 and earlier, LTS 2.492.2 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Computer/Create permission but without Computer/Extended Read permission to copy an agent, gaining access to its configuration.

Jenkins 2.504, LTS 2.492.3 requires Computer/Extended Read permission to copy an agent.

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:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
