CVE-2023-49783

No permission checks for editing/deleting records with CSV import form

Action may be required

If you have a custom implementation of BulkLoader, you should update your implementation to respect permissions when the return value of getCheckPermissions() is true.

If you are using any BulkLoader in your own project logic, or maintain a module which uses it, you should consider passing true to setCheckPermissions() if the data is provided by users.

Base CVSS: 4.3

Users who don't have edit or delete permissions for records exposed in a ModelAdmin can still edit or delete records using the CSV import form, provided they have create permissions.

The likelyhood of a user having create permissions but not having edit or delete permissions is low, but it is possible.

Note that this doesn't affect any ModelAdmin which has had the import form disabled via the showImportForm public property, nor does it impact the SecurityAdmin section.

The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.

CVE-2023-49783 has a CVSS score of 4.3 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.13.19, 2.1.8); upgrading removes the vulnerable code path.

1. What is CVE-2023-49783? CVE-2023-49783 is a medium-severity incorrect authorization vulnerability in silverstripe/admin (composer), affecting versions >= 1.0.0, < 1.13.19. It is fixed in 1.13.19, 2.1.8. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
2. How severe is CVE-2023-49783? CVE-2023-49783 has a CVSS score of 4.3 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of silverstripe/admin are affected by CVE-2023-49783? silverstripe/admin (composer) versions >= 1.0.0, < 1.13.19 is affected.
4. Is there a fix for CVE-2023-49783? Yes. CVE-2023-49783 is fixed in 1.13.19, 2.1.8. Upgrade to this version or later.
5. Is CVE-2023-49783 exploitable, and should I be worried? Whether CVE-2023-49783 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2023-49783 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2023-49783?
   • Upgrade silverstripe/admin to 1.13.19 or later
   • Upgrade silverstripe/admin to 2.1.8 or later
