Jenkins Git Parameter Plugin vulnerable to code injection due to inexhaustive parameter check

Description

Jenkins Git Parameter Plugin implements a choice build parameter that lists the configured Git SCM’s branches, tags, pull requests, and revisions.

Git Parameter Plugin 439.vb_0e46ca_14534 and earlier does not validate that the Git parameter value submitted to the build matches one of the offered choices.

This allows attackers with Item/Build permission to inject arbitrary values into Git parameters.

Git Parameter Plugin 444.vca_b_84d3703c2 validates that the Git parameter value submitted to the build matches one of the offered choices.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N 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:N)
Service keeps running; no real outage angle.
