Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-67084 is a file upload vulnerability in InvoicePlane through version 1.6.3 that allows authenticated attackers to upload arbitrary PHP files into the attachments directory, enabling remote code execution (RCE) when those files are later accessed. This issue is classified under CWE-616 and carries a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), reflecting its critical severity due to network accessibility, low attack complexity, and broad impact across confidentiality, integrity, and availability.
The vulnerability can be exploited by any authenticated user with low privileges over the network, requiring no user interaction. Successful exploitation allows attackers to execute arbitrary code on the server by uploading malicious PHP files that are stored and then remotely triggered, potentially leading to full server compromise given the changed scope and high impact metrics.
Mitigation guidance is available in advisories such as the Helx.io security advisory at https://www.helx.io/blog/advisory-invoice-plane/ and the InvoicePlane GitHub repository at https://github.com/InvoicePlane/InvoicePlane. The CVE was published on 2026-01-15T15:15:51.427.

Mitigating Controls (NIST 800-53 r5) AI
Engineering principles such as complete mediation and least privilege require the use of the canonical $_FILES array rather than attacker-writable globals.
Proper validation of all file-upload inputs stops attackers from supplying or overwriting the legacy global variables that the flawed code relies on.

Security testing in development can detect the legacy upload pattern before deployment.
Secure development lifecycle mandates proper input handling and file-upload validation, directly addressing the outdated global-variable approach.
Application security requirements include secure file-upload mechanisms that eliminate reliance on the four legacy PHP variables.
Secure architecture principles discourage unsafe global state, indirectly reducing exposure to variable-injection attacks.
Secure coding explicitly prohibits use of deprecated upload variables and requires validated, server-side file handling.
