CVE-2026-126480 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.6 (high) and affects openemr; fixed in 8.5.0.

## Summary

OpenEMR contains an SQL injection flaw in its CCR revandapprove route that lets a logged-in user with low privileges inject SQL remotely through request parameter names, with no user action needed. An attacker can use it to copy password hashes into patient fields or corrupt records.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Who should check

Anyone running OpenEMR before 8.5.0, especially sites using the CCR module's revandapprove route, which is reachable by any authenticated user

## Affected

- openemr: fixed in 8.5.0

## Description

OpenEMR before 8.5.0 contains an sql injection vulnerability in CcrTable::insertApprovedData() that allows authenticated users to inject SQL through request parameter names used as column names. Attackers can send crafted patient_data-*-sel parameters to the revandapprove route, lacking ACL and CSRF checks, to copy password hashes into patient fields or corrupt records.

## What to do

- Check your stack: if you ship or depend on openemr, upgrade to a fixed version (8.5.0) per the references below.
- For agents: to check a whole dependency tree, run the stack.check operation (execute) on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-126480 (OpenEMR before 8.5.0 SQL Injection via CCR revandapprove Parameter Names), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-126480 (entry last updated 2026-11-13):
Affected:
- openemr openemr: fixed in 8.5.0
Fixed versions: 8.5.0.
Conditions (all must be true for the bug to be hit):
- OpenEMR versions before 8.5.0 (source: https://www.vulncheck.com/advisories/openemr-before-8.5.0-sql-injection-via-ccr-revandapprove-parameter-names)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, low-privilege login, no user action.
CISA KEV: CVE-2026-126480 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126480 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

## FAQ

### Is CVE-2026-126480 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-126480

### What does this mean?

An authenticated user can inject SQL through patient_data column names used by the CCR revandapprove parameter. This lets them read any table in the database, including users_secure password hashes, and write those values into patient fields or corrupt patient demographic records.
