Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

### 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()`: - [[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L245)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L252)#L245) - [[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L253)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L252) - [CustomReportController.php](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L253) - [[Config/Listing/Dao.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Tool/Config/Listing/Dao.php#L44)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Tool/[Config/Listing/Dao.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Tool/Config/Listing/Dao.php#L52)#L44) - [Config/Listing/Dao.php](pimcore-12.3.3/bundles/CustomReportsBundle/src/Tool/Config/Listing/Dao.php#L52) However, `getAction()` only checks generic permissions and then loads the report directly by name: - [[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L146)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L149)#L146) - [[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L151)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L155)#L149) - [CustomReportController.php](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L151) - [CustomReportController.php](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L155) 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: - [[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L275)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L284)#L275) - [[CustomReportController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L313)](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L284) - [CustomReportController.php](pimcore-12.3.3/bundles/CustomReportsBundle/src/Controller/Reports/CustomReportController.php#L313) This report only treats unauthorized report-config retrieval as reproduced. The other execution paths should be verified separately. ### Preconditions -

Impact

An attacker with low-privileged backend access can read sensitive report metadata without authorization. This includes report names, grouping, display settings, data source configurations, column configurations, and sharing settings. Such unauthorized disclosure could lead to information leakage about internal reporting structures and data sources.

Summary

The vulnerability arises because the report listing endpoint filters reports based on sharing rules, while the report detail endpoint only checks generic permissions and loads reports directly by name. This discrepancy allows users without explicit access to a report to retrieve its configuration and metadata by direct request. Other report-related endpoints may also be affected but were not confirmed. The issue is a classic access control bypass (CWE-863) in Pimcore's CustomReports bundle.

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
