CVE-2026-42176 | Scoold: Persistent Admin Takeover by Overwriting the admins Configuration Setting via Forged JWT (missing `jti` validation)

Scoold is a Q&A and a knowledge sharing platform for teams. Prior to version 1.67.0, Scoold allows the admins configuration value to be modified through /api/config/set/admins with a forged Bearer token that is accepted as an admin API token. Once that setting is changed, the target email address is written to the application configuration file. The change does not become active immediately in the current process, because the ADMINS set is loaded once at startup. After a Scoold restart, though, the selected user is recognized as an administrator and gains access to the admin panel. This issue gives an attacker a reliable persistence path: write their own email into scoold.admins, wait for a restart or trigger one operationally, and the account comes back as admin. This issue has been patched in version 1.67.0.

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:H)
They need powerful rights—admin, root, or similar—before this pays off.
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: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:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
