Sharp and Toshiba Tec MFPs (multifunction printers) fail to properly authorize requests to directly access certain image data stored to the affected product.
AnalysisAI
Unauthenticated network access to stored image data affects Sharp and Toshiba Tec multifunction printers via a forced browsing vulnerability (CWE-425). Remote attackers without any credentials can directly request URLs referencing scanned or copied image data held on the device, bypassing the authorization layer entirely. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The MFP must be reachable over the network by the attacker - the CVSS vector AV:N confirms network reachability is the primary access requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reflects a network-reachable, low-complexity, unauthenticated information disclosure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker on the same network segment as a Sharp or Toshiba Tec MFP - or with access through a misconfigured firewall - enumerates the device's web interface and discovers predictable URL patterns for stored scan or copy jobs. By issuing direct unauthenticated HTTP GET requests to those URLs, the attacker retrieves image files of documents previously scanned or copied on the device, with no credentials required. … |
| Remediation | Apply firmware updates as released by Sharp and Toshiba Tec per their respective advisories: Sharp at https://global.sharp/corporate/info/product-security/advisory-list/2026-004/ and Toshiba Tec at https://www.toshibatec.com/information/20260731_01.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
