CVE-2026-41655 is a medium-severity Path Traversal (CWE-22) vulnerability. Its CVSS base score is 6.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Vulnerability Data
Admidio is an open-source user management solution. Prior to version 5.0.9, the ecard_preview.php endpoint does not validate that the ecard_template POST parameter is a safe filename before passing it to ECard::getEcardTemplate(). An authenticated user can supply a path traversal payload…

(e.g., ../config.php) to read arbitrary files accessible to the web server process, including adm_my_files/config.php which contains database credentials. This issue has been patched in version 5.0.9.

Why these techniques?
Path traversal in authenticated web endpoint directly enables arbitrary local file read (T1005), specifically targeting credential files (T1552.001).

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of ecard_template input to reject path traversal sequences before they reach file operations.
Ensures the web-server process runs with minimal filesystem privileges so that even a successful traversal cannot reach files such as adm_my_files/config.php.
Monitors for anomalous file-access patterns or unexpected reads of configuration files that would indicate exploitation of the traversal flaw.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
