CVE-2026-112292: CheckCle through 1.6.0 Missing Authorization via Empty PocketBase API Rules

Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.

Generated by VEDAS. Scores as of 2026-11-11 15:49 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.

What it is

CheckCle through 1.6.0 contains a missing authorization vulnerability that allows unauthenticated attackers to read, modify and delete records because shipped PocketBase collections use empty API rules. Attackers can query /api/collections/<name>/records endpoints to steal server_token values and alert_configurations secrets, disable alerting, alter status pages, or delete monitoring data.

Description quoted from the CVE record (assigned by VulnCheck, published 2026-10-19).

Weakness: Missing Authorization

Nuclei template (active check)

CheckCle - Missing Authorization

CheckCle through 1.6.0 ships PocketBase collections configured with empty API rules, so an unauthenticated attacker can read, modify, and delete monitoring records directly via the PocketBase REST API. This template lists the CheckCle “servers” collection through GET /api/collections/servers/records and confirms the PocketBase record listing is returned without authentication, exposing server inventory and secrets such as server_token values and alert_configurations data.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (GET /api/collections/servers/records?page=1&perPage=1); it decides using status, word matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
