CVE-2026-30892 WRITEUP NONE
Crun incorrectly parses `crun exec` option `-u`, leading to privilege escalation
crun is an open source OCI Container Runtime fully written in C. In versions 1.19 through 1.26, the `crun exec` option `-u` (`--user`) is incorrectly parsed. The value `1` is interpreted as UID 0 and GID 0 when it should have been UID 1 and GID 0. The process thus runs with higher privileges than expected. Version 1.27 patches the issue.
CVE-2026-32120 WRITEUP MEDIUM
OpenEMR has IDOR in Fee Sheet Product Save
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, an Insecure Direct Object Reference (IDOR) vulnerability in the fee sheet product save logic (`library/FeeSheet.class.php`) allows any authenticated user with fee sheet ACL access to delete, modify, or read `drug_sales` records belonging to arbitrary patients by manipulating the hidden `prod[][sale_id]` form field. The `save()` method uses the user-supplied `sale_id` in five SQL queries (SELECT, UPDATE, DELETE) without verifying that the record belongs to the current patient and encounter. Version 8.0.0.3 contains a patch.
CVSS 6.5
CVE-2026-33216 WRITEUP HIGH
NATS has MQTT plaintext password disclosure
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, for MQTT deployments using usercodes/passwords: MQTT passwords are incorrectly classified as a non-authenticating identity statement (JWT) and exposed via monitoring endpoints. Versions 2.11.14 and 2.12.6 contain a fix. As a workaround, ensure monitoring end-points are adequately secured. Best practice remains to not expose the monitoring endpoint to the Internet or other untrusted network users.
CVSS 8.6
CVE-2026-33219 WRITEUP MEDIUM
NATS is vulnerable to pre-auth DoS through WebSockets client service
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, a malicious client which can connect to the WebSockets port can cause unbounded memory use in the nats-server before authentication; this requires sending a corresponding amount of data. This is a milder variant of CVE-2026-27571. That earlier issue was a compression bomb, this vulnerability is not. Attacks against this new issue thus require significant client bandwidth. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, disable websockets if not required for project deployment.
CVSS 5.3
CVE-2026-33348 WRITEUP HIGH
OpenEMR has Stored XSS in patient encounter Eye Exam form $CHRONIC2 and $CHRONIC3
OpenEMR is a free and open source electronic health records and medical practice management application. Users with the `Notes - my encounters` role can fill Eye Exam forms in patient encounters. The answers to the form are displayed on the encounter page and in the visit history for the users with the same role. Versions prior to 8.0.0.3 have a stored cross-site scripting (XSS) vulnerability in the function to display the form answers, allowing any authenticated attacker with the specific role to insert arbitrary JavaScript into the system by entering malicious payloads to the form answers. The JavaScript code is later executed by any user with the form role when viewing the form answers in the patient encounter pages or visit history. Version 8.0.0.3 contains a patch.
CVSS 8.7

CVSS 7.2
CVE-2026-33911 WRITEUP MEDIUM
OpenEMR vulnerable to reflected XSS in graphs.php via title parameter
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the POST parameter `title` is reflected back in a JSON response built with `json_encode()`. Because the response is served with a `text/html` Content-Type, the browser interprets injected HTML/script tags rather than treating the output as JSON. An authenticated attacker can craft a request that executes arbitrary JavaScript in a victim's session. Version 8.0.0.3 contains a fix.
CVSS 5.4
CVE-2026-33912 WRITEUP MEDIUM

CVE-2026-33914 WRITEUP HIGH
OpenEMR has SQL Injection in PostCalendar Category Delete
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the PostCalendar module contains a blind SQL injection vulnerability in the `categoriesUpdate` administrative function. The `dels` POST parameter is read via `pnVarCleanFromInput()`, which only strips HTML tags and performs no SQL escaping. The value is then interpolated directly into a raw SQL `DELETE` statement that is executed unsanitized via Doctrine DBAL's `executeStatement()`. Version 8.0.0.3 patches the issue.
CVSS 7.2
CVE-2026-33915 WRITEUP MEDIUM
OpenEMR Missing ACL Checks on Insurance Company API Routes
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, five insurance company REST API routes are missing the `RestConfig::request_authorization_check()` call that every other data-modifying route in the standard API uses. This allows any authenticated API user to create and modify insurance company records even if their OpenEMR user account does not have administrative ACL permissions. Version 8.0.0.3 patches the issue.
CVSS 5.4
CVE-2026-33917 WRITEUP HIGH

CVSS 8.8
CVE-2026-33918 WRITEUP HIGH
OpenEMR Missing Authorization on Claim File Download Endpoint
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the billing file-download endpoint `interface/billing/get_claim_file.php` only verifies that the caller has a valid session and CSRF token, but does not check any ACL permissions. This allows any authenticated OpenEMR user — regardless of whether they have billing privileges — to download and permanently delete electronic claim batch files containing protected health information (PHI). Version 8.0.0.3 patches the issue.
CVSS 7.6
CVE-2026-33931 WRITEUP MEDIUM
OpenEMR has IDOR in Portal Payment Page that Allows Cross-Patient Record Access
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, an Insecure Direct Object Reference (IDOR) vulnerability in the patient portal payment page allows any authenticated portal patient to access other patients' payment records — including invoice/billing data (PHI) and payment card metadata — by manipulating the `recid` query parameter in `portal/portal_payment.php`. Version 8.0.0.3 patches the issue.
CVSS 6.5
CVE-2026-33932 WRITEUP HIGH
OpenEMR has Stored XSS in CCDA Preview via Unsanitized linkHtml Attributes

CVE-2026-33933 WRITEUP MEDIUM
Reflected XSS via Unescaped contextName Parameter in Custom Template Editor
OpenEMR is a free and open source electronic health records and medical practice management application. Starting in version 7.0.2.1 and prior to version 8.0.0.3, a reflected cross-site scripting (XSS) vulnerability in the custom template editor allows an attacker to execute arbitrary JavaScript in an authenticated staff member's browser session by sending them a crafted URL. The attacker does not need an OpenEMR account. Version 8.0.0.3 patches the issue.
CVSS 6.1
CVE-2026-33934 WRITEUP MEDIUM
OpenEMR's Missing Authorization in show-signature.php Allows Portal Patients to Read Staff Signatures
OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0.3 have a missing authorization check in `portal/sign/lib/show-signature.php` that allows any authenticated patient portal user to retrieve the drawn signature image of any staff member by supplying an arbitrary `user` value in the POST body. The companion write endpoint (`save-signature.php`) was already hardened against this same issue, but the read endpoint was not updated to match. Version 8.0.0.3 patches the issue.
CVSS 4.3
CVE-2026-34051 WRITEUP MEDIUM

OpenEMR Missing Authorization in Procedure Order AJAX Deletion Handler
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, missing authorization in the AJAX deletion endpoint `interface/forms/procedure_order/handle_deletions.php` allows any authenticated user, regardless of role, to irreversibly delete procedure orders, answers, and specimens belonging to any patient in the system. Version 8.0.0.3 patches the issue.
CVSS 7.1
CVE-2026-34055 WRITEUP HIGH
OpenEMR has IDOR in Patient Notes Web UI allows unauthorized note access/modification
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the legacy patient notes functions in `library/pnotes.inc.php` perform updates and deletes using `WHERE id = ?` without verifying that the note belongs to a patient the user is authorized to access. Multiple web UI callers pass user-controlled note IDs directly to these functions. This is the same class of vulnerability as CVE-2026-25745 (REST API IDOR), but affects the web UI code paths. Version 8.0.0.3 patches the issue.
