• CVE-2026-34382: 0.13% estimated exploitation activity in the next 30 days; percentile 2.45 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

Reported by: Juan Felipe Oz @JF0x0r LinkedIn Summary The delete mode handler in mylistfunction.php permanently deletes list configurations without validating a CSRF token. An attacker who can lure an authenticated user to a malicious page can silently destroy that user's list configurations — including organization-wide shared lists when the victim holds administrator rights. Vulnerable Code File: modules/groups-roles/mylistfunction.php The CSRF token validation at lines 81–82 is scoped exclusively to the save, saveas, and savetemporary modes: <img width="857" height="162" alt="imagen" src="https://github.com/user-attachments/assets/caec390e-ba6f-40f0-bb9c-a8870679da3d" / The delete case at lines 159–161 executes the destructive operation with no token check: <img width="560" height="133" alt="imagen" src="https://github.com/user-attachments/assets/2d5eff8e-bbce-49b9-b6d5-77f4e2e6db69" / A global input guard at lines 40–48 requires a non-empty column[] POST parameter for all modes…

# Patch Next advisory brief: CVE-2026-34382

Advisory: Admidio has Missing CSRF Protections on Custom List Deletion in mylist_function.php
IDs: CVE-2026-34382, GHSA-g3mx-8jm6-rc85
Record: https://patchnext.com/advisories/cve-2026-34382 (revision 1, source checked 26 Oct 2026, 14:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: admidio/admidio 5.0.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist admidio/admidio: affected >= 5.0.0, <= 5.0.7; fixed in 5.0.8

## 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-g3mx-8jm6-rc85 (GitHub-reviewed advisory GHSA-g3mx-8jm6-rc85 lists affected ranges: Packagist admidio/admidio >=5.0.0 <=5.0.7)
