Summary
Vulnerability reported (CVE-2026-100613). Data can be tampered with by attackers. Exploitable via channel_permission_overrides.
Original description
The description as published by the source.
capgo.app is an over-the-air (OTA) update platform for Capacitor apps. In all versions up to and including the current release (no patch available at time of publication), the transfer_app() database function transfers an app, its channels, versions and related records to a destination organization without deleting or revalidating existing rows in channel_permission_overrides. As a result, a user who legitimately held a channel permission override while a member of the source organization retains that override after the transfer, even though they have no membership and no RBAC binding in the destination organization. Using their own authenticated JWT against the PostgREST API, such a former member can modify the destination-owned channel to point at a different bundle, causing the /updates endpoint to serve an attacker-selected application version to devices. The previously proposed fix for GHSA-626c-p6fq-3whq (PR #3093), which validates organization membership when an override is created or updated, does not remove overrides that became stale as a result of an app transfer.

CVE-2026-100613 — CWE-863 / CVSS v3 5.3
Attack vector: remote (network-reachable) / no user interaction
Attack surface: channel_permission_overrides
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.
Incorrect authorization (CWE-863) has been reported. Attackers reach the vulnerable code path via channel_permission_overrides.
Check the vendor advisory for the affected versions. Attack surface: channel_permission_overrides.
Severity: Medium (CVSS 5.3/10). Data can be tampered with by attackers.
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 request patterns matching this CVE's known IOCs. Audit SBOM/dependencies to find affected services.
