• CVE-2025-69212: 1.92% estimated exploitation activity in the next 30 days; percentile 79.87 (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.

Summary A critical OS Command Injection vulnerability exists in the P7M (signed XML) file decoding functionality. An authenticated attacker can upload a ZIP file containing a .p7m file with a malicious filename to execute arbitrary system commands on the server. Vulnerable Code File: src/Util/XML.php:100 The Problem: - The $file parameter is passed directly into exec() without sanitization - Although wrapped in double quotes, an attacker can escape them - The filename comes from uploaded ZIP archives (user-controlled) Attack Vector Entry Points: 1. plugins/importFEZIP/actions.php:126 (when automatic import is enabled) 2. plugins/importFE/src/FatturaElettronica.php:56 (constructor) Attack Flow: 1. Attacker creates ZIP with malicious filename 2. Upload ZIP via importFEZIP plugin 3. Application extracts ZIP and iterates files 4. For .p7m files, decodeP7M() is called 5. Malicious filename is injected into exec() command 6. Arbitrary command executes as web server user Proof of Concept ⚠️…

# Patch Next advisory brief: CVE-2025-69212

Advisory: OpenSTAManager has an OS Command Injection in P7M File Processing
IDs: CVE-2025-69212, GHSA-25fp-8w8p-mx36
Record: https://patchnext.com/advisories/cve-2025-69212 (revision 1, source checked 26 Oct 2026, 14:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist devcode-it/openstamanager: affected <= 2.9.8

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on devcode-it/openstamanager.
- 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-25fp-8w8p-mx36 (GitHub-reviewed advisory GHSA-25fp-8w8p-mx36 lists affected ranges: Packagist devcode-it/openstamanager >=0 <=2.9.8)
