Summary
Zipline through 4.6.2 contains an authorization bypass vulnerability that allows authenticated administrators to read superadmin secrets because GET /api/users and GET /api/users/:id lack the canInteract check. Attackers can retrieve plaintext totpSecret and OAuth tokens to bypass 2FA and take over superadmin accounts, while any authenticated user can enumerate other users' folders via GET /api/user/folders.
Who should check
Teams running diced zipline 4.6.2 or earlier with multiple user roles, including admin and superadmin accounts.

What to do
Check whether your setup matches what the bug needs.
Zipline version 4.6.2 and earlier is affected. The user-data bypass requires an authenticated ADMIN account.Workaround: The checked facts describe no workaround. They state only that the bypass requires an authenticated ADMIN account.
Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-126941 (Zipline through 4.6.2 Privilege Escalation via Missing Role Checks on User Endpoints), using the cve.now data below.
Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.
What cve.now has for CVE-2026-126941 (entry last updated 2026-11-13):
Affected:
- diced zipline: through 4.6.2
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Zipline version 4.6.2 and earlier is affected. (source: https://www.vulncheck.com/advisories/zipline-through-4.6.2-privilege-escalation-via-missing-role-checks-on-user-endpoints)
- The user-data bypass requires an authenticated ADMIN account. (source: https://github.com/diced/zipline/security/advisories/GHSA-8643-cr38-p6qj)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, high-privilege login, no user action.
CISA KEV: CVE-2026-126941 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126941 only. If you also check another CVE, look up its own KEV status; never assume it from this one.
How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.
Verify against the linked advisories before concluding, and cite the date you read each one:
- https://github.com/diced/zipline/security/advisories/GHSA-8643-cr38-p6qj
- https://www.vulncheck.com/advisories/zipline-through-4.6.2-privilege-escalation-via-missing-role-checks-on-user-endpoints
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-126941
Is CVE-2026-126941 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
An authenticated ADMIN account can read a SUPERADMIN's 2FA secret or OAuth tokens. That can enable 2FA bypass, OAuth account takeover, and privilege escalation. The bug also lets an attacker enumerate other users' folders.Source: vulncheck.com, github.com
Which versions are affected by CVE-2026-126941?
zipline: through 4.6.2.Source: cve.now feed data
Am I affected, and how do I check?
Zipline version 4.6.2 and earlier is affected. The user-data bypass requires an authenticated ADMIN account. Check the installed Zipline version and whether ADMIN accounts exist in the deployment.Source: vulncheck.com, github.com
How do I fix CVE-2026-126941?
The checked facts name no fixed version and no vendor patch identifiers, so no upgrade target can be given from them. Check the vendor's advisory for a fixed release.Source: vulncheck.com, github.com
What if there's no patch?
The checked facts describe no workaround. They state only that the bypass requires an authenticated ADMIN account.Source: vulncheck.com, github.com
