# CVE-2026-32817: Admidio is Missing Authorization and CSRF Protection on Document and Folder Deletion

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.5% , percentile 42: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 42% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes admidio/admidio (Composer (PHP)) >= 5.0.0, <= 5.0.6, fixed in 5.0.7 . Check your lockfile, including transitive dependencies.

## What it is

Admidio is an open-source user management solution. In versions 5.0.0 through 5.0.6, the documents and files module does not verify whether the current user has permission to delete folders or files. The folderdelete and filedelete action handlers in modules/documents-files.php only perform a VIEW authorization check (getFolderForDownload / getFileForDownload) before calling delete(), and they never validate a CSRF token. Because the target UUIDs are read from $GET, deletion can be triggered by a plain HTTP GET request. When the module is in public mode (documentsfilesmoduleenabled = 1) and a folder is marked public (folpublic = true), an unauthenticated attacker can permanently destroy the entire document library. Even when the module requires login, any user with view-only access can delete content they are only permitted to read. This issue has been fixed in version 5.0.7.

## Affected packages

- Composer (PHP) `admidio/admidio` >= 5.0.0, <= 5.0.6 → fixed: 5.0.7

## Affected products (CVE record)

- Admidio admidio: >= 5.0.0, < 5.0.7

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.50% probability of exploitation activity in the next 30 days; percentile 42.
