Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim user actively opens a malicious file within Adobe Lightroom Classic on a system running an affected version (15.4.1 or earlier). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reflects a locally-delivered, low-complexity attack requiring user interaction, with full confidentiality, integrity, and availability impact to the compromised process. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious image or Lightroom-compatible file that embeds oversized data in a field the application parses without adequate bounds checking. The file is delivered to a target photographer or designer via email, file-sharing platform, or a compromised asset library. … |
| Remediation | The primary remediation is upgrading Adobe Lightroom Classic to version 15.5 or later, as released and documented by Adobe in security bulletin APSB26-94 (https://helpx.adobe.com/security/products/lightroom/apsb26-94.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
