CVE-2026-23627 WRITEUP HIGH
OpenEMR < 8.0.0 - Authenticated SQL Injection via Immunization Module Patient ID Parameter
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an SQL injection vulnerability in the Immunization module allows any authenticated user to execute arbitrary SQL queries, leading to complete database compromise, PHI exfiltration, credential theft, and potential remote code execution. The vulnerability exists because user-supplied `patient_id` values are directly concatenated into SQL WHERE clauses without parameterization or escaping. Version 8.0.0 patches the issue.
CVSS 8.8
CVE-2026-24005 WRITEUP NONE
Kruise 1.7.0-1.7.4 and 1.8.0-1.8.2 - Server-Side Request Forgery via PodProbeMarker Host Field
Kruise provides automated management of large-scale applications on Kubernetes. Prior to versions 1.8.3 and 1.7.5, PodProbeMarker allows defining custom probes with TCPSocket or HTTPGet handlers. The webhook validation does not restrict the Host field in these probe configurations. Since kruise-daemon runs with hostNetwork=true, it executes probes from the node network namespace. An attacker with PodProbeMarker creation permission can specify arbitrary Host values to trigger SSRF from the node, perform port scanning, and receive response feedback through NodePodProbe status messages. Versions 1.8.3 and 1.7.5 patch the issue.
CVE-2026-24487 WRITEUP MEDIUM
OpenEMR < 8.0.0 - Unauthenticated Authorization Bypass in FHIR CareTeam Endpoint
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an authorization bypass vulnerability in the FHIR CareTeam resource endpoint allows patient-scoped FHIR tokens to access care team data for all patients instead of being restricted to only the authenticated patient's data. This could potentially lead to unauthorized disclosure of Protected Health Information (PHI), including patient-provider relationships and care team structures across the entire system. The issue occurs because the `FhirCareTeamService` does not implement the `IPatientCompartmentResourceService` interface and does not pass the patient binding parameter to the underlying service, bypassing the patient compartment filtering mechanism. Version 8.0.0 contains a patch for this issue.
CVSS 6.5
CVE-2026-24890 WRITEUP HIGH
OpenEMR < 8.0.0 - Authenticated Authorization Bypass via Patient Portal Signature Endpoint
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an authorization bypass vulnerability in the patient portal signature endpoint allows authenticated portal users to upload and overwrite provider signatures by setting `type=admin-signature` and specifying any provider user ID. This could potentially lead to signature forgery on medical documents, legal compliance violations, and fraud. The issue occurs when portal users are allowed to modify provider signatures without proper authorization checks. Version 8.0.0 fixes the issue.
CVSS 8.1
CVE-2026-24908 WRITEUP CRITICAL
OpenEMR < 8.0.0 - Authenticated SQL Injection via Patient REST API _sort Parameter
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an SQL injection vulnerability in the Patient REST API endpoint allows authenticated users with API access to execute arbitrary SQL queries through the `_sort` parameter. This could potentially lead to database access, PHI (Protected Health Information) exposure, and credential compromise. The issue occurs when user-supplied sort field names are used in ORDER BY clauses without proper validation or identifier escaping. Version 8.0.0 fixes the issue.
CVSS 9.9
CVE-2026-25164 WRITEUP HIGH
OpenEMR < 8.0.0 - Missing Authorization for Document and Insurance REST API Routes
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the REST API route table in `apis/routes/_rest_routes_standard.inc.php` does not call `RestConfig::request_authorization_check()` for the document and insurance routes. Other patient routes in the same file (e.g. encounters, patients/med) call it with the appropriate ACL. As a result, any valid API bearer token can access or modify every patient's documents and insurance data, regardless of the token’s OpenEMR ACLs—effectively exposing all document and insurance PHI to any authenticated API client. Version 8.0.0 patches the issue.
CVSS 8.1
CVE-2026-25220 WRITEUP MEDIUM
OpenEMR <8.0.0 - Privilege Escalation
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the Message Center accepts the URL parameter `show_all=yes` and passes it to `getPnotesByUser()`, which returns all internal messages (all users’ notes). The backend does not verify that the requesting user is an administrator before honoring `show_all=yes`. The "Show All" link is also visible to non-admin users. As a result, any authenticated user can view the entire internal message list by requesting `messages.php?show_all=yes`. Version 8.0.0 patches the issue.
CVSS 6.5
CVE-2026-25476 WRITEUP HIGH
OpenEMR < 8.0.0 - Insufficient Session Expiration via skip_timeout_reset Parameter
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the session expiration check in `library/auth.inc.php` runs only when `skip_timeout_reset` is not present in the request. When `skip_timeout_reset=1` is sent, the entire block that calls `SessionTracker::isSessionExpired()` and forces logout on timeout is skipped. As a result, any request that includes this parameter (e.g. from auto-refresh pages like the Patient Flow Board) never runs the expiration check: expired sessions can continue to access data indefinitely, abandoned workstations stay active, and an attacker with a stolen session cookie can keep sending `skip_timeout_reset=1` to avoid being logged out. Version 8.0.0 fixes the issue.
CVSS 7.5
CVE-2026-25554 WRITEUP MEDIUM
OpenSIPS 3.1-3.6.3 - SQL Injection via Unverified JWT Tag Claim in auth_jwt Module
OpenSIPS versions 3.1 before 3.6.4 containing the auth_jwt module (prior to commit 3822d33) contain a SQL injection vulnerability in the jwt_db_authorize() function in modules/auth_jwt/authorize.c when db_mode is enabled and a SQL database backend is used. The function extracts the tag claim from a JWT without prior signature verification and incorporates the unescaped value directly into a SQL query. An attacker can supply a crafted JWT with a malicious tag claim to manipulate the query result and bypass JWT authentication, allowing impersonation of arbitrary identities.
CVSS 6.5
CVE-2026-25743 WRITEUP MEDIUM
OpenEMR < 8.0.0 - Authenticated Stored Cross-Site Scripting via Form Answers
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, users with the "Forms administration" role can fill questionnaires ("forms") in patient encounters. The answers to the forms are displayed on the encounter page and in the visit history for the users with the same role. There exists 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 fixes the issue.
CVSS 4.8
CVE-2026-25746 WRITEUP HIGH
OpenEMR < 8.0.0 - Authenticated SQL Injection in Prescription Listing
OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0 contain a SQL injection vulnerability in prescription that can be exploited by authenticated attackers. The vulnerability exists due to insufficient input validation in the prescription listing functionality. Version 8.0.0 fixes the vulnerability.
CVSS 8.8
CVE-2026-25746 WRITEUP HIGH
OpenEMR < 8.0.0 - Authenticated SQL Injection in Prescription Listing
OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0 contain a SQL injection vulnerability in prescription that can be exploited by authenticated attackers.

CVSS 8.8
CVE-2026-25929 WRITEUP MEDIUM
OpenEMR < 8.0.0 - Authenticated Patient Photo Access Control Bypass via Document Controller
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the document controller’s `patient_picture` context serves the patient’s photo by document ID or patient ID without verifying that the current user is authorized to access that patient. An authenticated user with document ACL can supply another patient’s ID and retrieve their photo. Version 8.0.0 fixes the issue.
CVSS 6.5
CVE-2026-25930 WRITEUP MEDIUM
OpenEMR < 8.0.0 - Authenticated Authorization Bypass via Layout-Based Form Printable View
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the Layout-Based Form (LBF) printable view accepts `formid` and `visitid` (or `patientid`) from the request and does not verify that the form belongs to the current user’s authorized patient/encounter. An authenticated user with LBF access can enumerate form IDs and view or print any patient’s encounter forms. Version 8.0.0 fixes the issue.
CVSS 6.5
CVE-2026-25941 WRITEUP MEDIUM
FreeRDP 2.0.0-2.11.7 - Out-of-bounds Read via RDPGFX WIRE_TO_SURFACE_2 PDU
FreeRDP is a free implementation of the Remote Desktop Protocol. Versions on the 2.x branch prior to to 2.11.8 and on the 3.x branch prior to 3.23.0 have an out-of-bounds read vulnerability in the FreeRDP client's RDPGFX channel that allows a malicious RDP server to read uninitialized heap memory by sending a crafted WIRE_TO_SURFACE_2 PDU with a `bitmapDataLength` value larger than the actual data in the packet. This can lead to information disclosure or client crashes when a user connects to a malicious server. Versions 2.11.8 and 3.23.0 fix the issue.
CVSS 4.3
CVE-2026-25942 WRITEUP HIGH
FreeRDP <3.23.0 - Memory Corruption
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_execute_result` indexes the global `error_code_names[]` array (7 elements, indices 0–6) with an unchecked `execResult->execResult` value received from the server, allowing an out-of-bounds read when the server sends an `execResult` value of 7 or greater. Version 3.23.0 fixes the issue.
CVSS 7.5
CVE-2026-25952 WRITEUP CRITICAL
FreeRDP < 3.23.0 - Use-After-Free in xf_SetWindowMinMaxInfo
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_SetWindowMinMaxInfo` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` in `xf_rail_server_min_max_info` returns an unprotected pointer from the `railWindows` hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue.
CVSS 9.8
CVE-2026-25953 WRITEUP CRITICAL
FreeRDP < 3.23.0 - Use-After-Free in xf_rail Window Handling
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_AppUpdateWindowFromSurface` reads from a freed `xfAppWindow` because the RDPGFX DVC thread obtains a bare pointer via `xf_rail_get_window` without any lifetime protection, while the main thread can concurrently delete the window through a fastpath window-delete order. Version 3.23.0 fixes the issue.
CVSS 9.8
CVE-2026-25954 WRITEUP HIGH
FreeRDP < 3.23.0 - Use-After-Free in xf_rail_server_local_move_size
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_local_move_size` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` returns an unprotected pointer from the `railWindows` hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue.
CVSS 7.5
CVE-2026-25955 WRITEUP CRITICAL
FreeRDP < 3.23.0 - Use-After-Free in xf_AppUpdateWindowFromSurface
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_AppUpdateWindowFromSurface` reuses a cached `XImage` whose `data` pointer references a freed RDPGFX surface buffer, because `gdi_DeleteSurface` frees `surface->data` without invalidating the `appWindow->image` that aliases it. Version 3.23.0 fixes the issue.
CVSS 9.8
CVE-2026-25959 WRITEUP CRITICAL
FreeRDP < 3.23.0 - Use-After-Free in Clipboard Data Handling
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_cliprdr_provide_data_` passes freed `pDstData` to `XChangeProperty` because the cliprdr channel thread calls `xf_cliprdr_server_format_data_response` which converts and uses the clipboard data without holding any lock, while the X11 event thread concurrently calls `xf_cliprdr_clear_cached_data` → `HashTable_Clear` which frees the same data via `xf_cached_data_free`, triggering a heap use after free. Version 3.23.0 fixes the issue.
CVSS 9.8
CVE-2026-25997 WRITEUP CRITICAL
FreeRDP < 3.23.0 - Use-After-Free in Clipboard Format Handling
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_clipboard_format_equal` reads freed `lastSentFormats` memory because `xf_clipboard_formats_free` (called from the cliprdr channel thread during auto-reconnect) frees the array while the X11 event thread concurrently iterates it in `xf_clipboard_changed`, triggering a heap use after free. Version 3.23.0 fixes the issue.
CVSS 9.8
CVE-2026-26271 WRITEUP MEDIUM
FreeRDP < 3.23.0 - Buffer Over-read in TS_ICON_INFO Icon Data Processing
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread in `freerdp_image_copy_from_icon_data()` (libfreerdp/codec/color.c) can be triggered by crafted RDP Window Icon (TS_ICON_INFO) data. The bug is reachable over the network when a client processes icon data from an RDP server (or from a man-in-the-middle). Version 3.23.0 fixes the issue.
CVSS 5.3
CVE-2026-26717 WRITEUP MEDIUM
Richie < 3.3.0 - Observable Timing Discrepancy in HMAC Signature Verification
An issue in OpenFUN Richie (LMS) in src/richie/apps/courses/api.py. The application used the non-constant time == operator for HMAC signature verification in the sync_course_run_from_request function. This allows remote attackers to forge valid signatures and bypass authentication by measuring response time discrepancies
