CVE-2026-56124: shimosyan phpUploader advisory

Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.

What it is

phpUploader before 2.0.2 contains an unauthenticated information disclosure vulnerability that allows remote attackers to access the full contents of the uploaded-files database table by visiting any page of the application. The index model executes an unbounded SELECT query and embeds the complete JSON-encoded result set in an inline script block, exposing uploader IP addresses, Argon2ID key hashes, internal filenames, and SHA-256 fingerprints.

Description quoted from the CVE record (assigned by VulnCheck, published 2026-06-29).

Weakness: Exposure of Private Personal Information to an Unauthorized Actor; Exposure of Sensitive System Information to an Unauthorized Control Sphere

How it can be exploited

Exploitable over the network with low attack complexity with no special attack requirements needing no privileges and no user interaction. Impact: confidentiality high, integrity none, availability none. CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N

CISA assessment (SSVC): CISA has no evidence of exploitation. Automatable: yes. Technical impact: partial.

How to detect it

Nuclei template (active check)

phpUploader - Unauthenticated Information Disclosure
phpUploader before 2.0.2 runs an unbounded “SELECT * FROM uploaded” and embeds the complete result set as window.fileData in an inline script on the index page, exposing every uploaded file’s sensitive columns (uploader IP addresses, Argon2ID download/delete key hashes, internal stored filenames and SHA-256 fingerprints) to any unauthenticated visitor. This template requests the index page and confirms the leak by matching window.fileData together with the sensitive stored_file_name column, which the fix (which restricts the query to a public column allowlist) removes from the response.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (GET /); it decides using status, word matchers. Severity in the template: high. Marked as not yet verified against a live vulnerable target.

Run it against a host you own or are authorised to test:
