Summary
Vulnerability reported (CVE-2026-107761). Risk of unauthorized operations or information disclosure. Exploitable via GET /user/organizations.
Original description
The description as published by the source.
Several Postiz endpoints return the complete database row of the record they operate on instead of only the fields the client needs. Two of them include secrets the caller is not meant to receive.
The public API's channel delete returns the deleted integration row, including the channel's platform access token and refresh token. A third-party OAuth app permitted to delete a channel therefore receives that channel's social platform credentials and can use them against the connected account directly, outside Postiz.
GET /user/organizations returns each organization row, including its API key, to every member of the organization. The API key is intended for admins only, so a member with a lower role can obtain it and call the public API on behalf of the organization.
Both endpoints require a valid session, API key or OAuth token and are scoped to the caller's own organization. There is no anonymous access and no cross-tenant exposure.

CVE-2026-107761 — CWE-201
Attack surface: GET /user/organizations
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
A vulnerability (CWE-201) has been reported. Attackers reach the vulnerable code path via GET /user/organizations.
Check the vendor advisory for the affected versions. Attack surface: GET /user/organizations.
Severity: ?. Risk of unauthorized operations or information disclosure.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual GET /user/organizations requests with malformed payloads or SQL meta-characters. Audit SBOM/dependencies to find affected services.
