Summary

CustomReports uses inconsistent authorization between the report listing endpoint and the report detail endpoint.

  • The listing flow filters reports based on report-sharing rules
  • The detail flow only checks generic reports or reports_config permissions

As a result, a low-privileged backend user who was not granted access to a report can still read that report directly by name even though it does not appear in the user's visible report list.

In the local Docker reproduction:

  • The report poc-secret-report was not visible to the low-privileged user in the report list
  • The same user was still able to retrieve the report configuration directly by name

Root Cause

The listing flow in getReportConfigAction() filters reports through loadForGivenUser():

However, getAction() only checks generic permissions and then loads the report directly by name:

This means the same report object is protected by different authorization models depending on which endpoint is used. The result is a classic "not visible in list, but readable by direct request" access-control bypass.

Impact

An attacker can read sensitive report metadata without authorization, including:

  • Report name
  • Grouping information
  • Display and icon metadata
  • Data source configuration
  • Column configuration
  • Sharing settings

From the source code, other report endpoints such as data, chart, create-csv, and download-csv also resolve reports by name in a similar way:

This report only treats unauthorized report-config retrieval as reproduced. The other execution paths should be verified separately.

Preconditions

  • The attacker is an authenticated backend user
  • The attacker has the reports permission
  • The target report is not globally shared and is not shared with that user or the user's roles

Reproduction Steps

  1. Create a low-privileged user named auditor_customreports with the reports permission.
  2. Create a report named poc-secret-report with:
  • shareGlobally = false
  • sharedUserNames = ['admin']
  1. As auditor_customreports, request the visible report list and verify that poc-secret-report is absent.
  2. As the same user, call getAction(name=poc-secret-report) directly.
  3. Verify that the response still contains the report configuration.

Reproduction command:

bash
cd pimcore-12.3.3-repro
docker compose exec -T php php poc_customreports.php

Reproduction Result

Relevant PoC output:

json
{
  "vulnerability": "customreports_share_bypass",
  "user": {
    "name": "auditor_customreports",
    "permissions": [
      "reports"
    ]
  },
  "target_report": {
    "name": "poc-secret-report",
    "shared_to": [
      "admin"
    ],
    "share_globally": false
  },
  "result": {
    "report_visible_in_list": false,
    "listed_report_names": [],
    "direct_get_returned_name": "poc-secret-report",
    "direct_get_shared_user_names": [
      "admin"
    ]
  }
}

This shows that:

  • The current user cannot see the report in the visible report list
  • The same user can still retrieve the report configuration directly

This confirms that the share-bypass issue is practically exploitable.

Security Impact

  • Unauthorized disclosure of report configuration
  • Disclosure of sharing scope and internal report structure
  • Potential leakage of data-source and query organization details
  • Useful reconnaissance for follow-on unauthorized execution or export paths

Remediation

  1. Add object-level sharing checks to getAction() equivalent to loadForGivenUser().
  2. Centralize authorization into a single "can current user access this report?" function reused by get, data, chart, create-csv, and download-csv.
  3. Return 403 for unshared reports.
  4. Add regression tests to ensure that users with reports permission but without report-sharing access cannot retrieve report details.

AnalysisAI

Broken access control in Pimcore's CustomReports bundle (composer package pimcore/pimcore, versions ≤ 12.3.5) lets an authenticated low-privileged backend user who holds only the generic reports permission read the full configuration of custom reports they were never granted access to. The report detail endpoint (getAction) validates only coarse reports/reports_config permissions, whereas the listing endpoint enforces per-report sharing rules through loadForGivenUser(); consequently a report hidden from a user's visible list can still be retrieved directly by name. …

Within 24 hours: Identify all Pimcore installations running pimcore/pimcore versions ≤12.3.5 and apply the vendor patch available in GHSA-jwcc-gv4m-93x6. Within 7 days: Verify patch deployment on all systems and audit backend user access logs for unauthorized report configuration retrievals by low-privilege accounts. …
