| CVE-2026-5442 | 緊急9.8 | A heap buffer overflow vulnerability exists in the DICOM image decoder. Dimension fields are encoded using Value Representation (VR) Unsigned Long (UL), instead of the expected VR Unsigned Short (US), which allows extremely large dimensions to be processed. This causes an integer overflow during frame size calculation | 09/04/2026 |
| CVE-2026-5441 | 高7.1 | An out-of-bounds read vulnerability exists in the `DecodePsmctRle1` function of `DicomImageDecoder.cpp`. The `PMSCT_RLE1` decompression routine, which decodes the proprietary Philips Compression format, does not properly validate escape markers placed near the end of the compressed data stream. A crafted sequence at th | 09/04/2026 |
| CVE-2026-5440 | 高7.5 | A memory exhaustion vulnerability exists in the HTTP server due to unbounded use of the `Content-Length` header. The server allocates memory directly based on the attacker supplied header value without enforcing an upper limit. A crafted HTTP request containing an extremely large `Content-Length` value can trigger exc | 09/04/2026 |
| CVE-2026-5439 | 高7.5 | A memory exhaustion vulnerability exists in ZIP archive processing. Orthanc automatically extracts ZIP archives uploaded to certain endpoints and trusts metadata fields describing the uncompressed size of archived files. An attacker can craft a small ZIP archive containing a forged size value, causing the server to all | 09/04/2026 |
| CVE-2026-5438 | 高7.5 | A gzip decompression bomb vulnerability exists when Orthanc processes HTTP request with `Content-Encoding: gzip`. The server does not enforce limits on decompressed size and allocates memory based on attacker-controlled compression metadata. A specially crafted gzip payload can trigger excessive memory allocation and e | 09/04/2026 |
| CVE-2026-5437 | 高7.5 | An out-of-bounds read vulnerability exists in `DicomStreamReader` during DICOM meta-header parsing. When processing malformed metadata structures, the parser may read beyond the bounds of the allocated metadata buffer. Although this issue does not typically crash the server or expose data directly to the attacker, it r | 09/04/2026 |
| CVE-2025-0896 | 緊急9.8 | Orthanc server prior to version 1.5.8 does not enable basic authentication by default when remote access is enabled. This could result in unauthorized access by an attacker. | 13/02/2025 |
| CVE-2024-22725 | 中6.1 | Orthanc versions before 1.12.2 are affected by a reflected cross-site scripting (XSS) vulnerability. The vulnerability was present in the server's error reporting. | 24/01/2024 |
| CVE-2023-7238 | 中6.1 |
A XSS payload can be uploaded as a DICOM study and when a user tries to view the infected study inside the Osimis WebViewer the XSS vulnerability gets triggered. If exploited, the attacker will be able to execute arbitrary JavaScript code inside the victim's browser.

| CVE-2023-33466 | 高8.8 | Orthanc before 1.12.0 allows authenticated users with access to the Orthanc API to overwrite arbitrary files on the file system, and in specific deployment scenarios allows the attacker to overwrite the configuration, which can be exploited to trigger Remote Code Execution (RCE). | 29/06/2023 |
