• CVE-2024-38529: 1.24% estimated exploitation activity in the next 30 days; percentile 69.32 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Description: Remote Code Execution Vulnerability has been identified in the Message module of the Admidio Application, where it is possible to upload a PHP file in the attachment. The uploaded file can be accessed publicly through the URL {admidiobaseurl}/admmyfiles/messagesattachments/{filename}. The vulnerability is caused due to the lack of file extension verification, allowing malicious files to be uploaded to the server and public availability of the uploaded file. An attacker can upload a PHP web shell that executes OS commands on the server, compromising the application server. Note: I am using the docker-compose.yaml file from https://github.com/Admidio/admidio/blob/master/README-Docker.md#docker-compose-usage official documentation. Impact: An attacker can exploit this flaw to upload a PHP web shell, which can be used to execute arbitrary commands on the server. This can lead to a complete compromise of the application server, allowing the attacker to: - Execute arbitrary…

# Patch Next advisory brief: CVE-2024-38529

Advisory: Admidio Vulnerable to RCE via Arbitrary File Upload in Message Attachment
IDs: CVE-2024-38529, GHSA-g872-jwwr-vggm
Record: https://patchnext.com/advisories/cve-2024-38529 (revision 1, source checked 26 Oct 2026, 14:25 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: admidio/admidio 4.3.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist admidio/admidio: affected < 4.3.10; fixed in 4.3.10

## Suggested inspection (read-only)
- Packagist admidio/admidio: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on admidio/admidio.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-g872-jwwr-vggm (GitHub-reviewed advisory GHSA-g872-jwwr-vggm lists affected ranges: Packagist admidio/admidio >=0 <4.3.10)
