Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim is running Adobe Lightroom Classic version 15.4.1 or earlier on their local workstation, and must actively open a maliciously crafted file - a RAW image, DNG, catalog, or other supported format - within Lightroom Classic. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.8 (AV:L/AC:L/PR:N/UI:R) is appropriate: attack vector is local because the victim must open a file on their workstation, complexity is low once a weaponized file is crafted, no privileges are required of the attacker, but user interaction is mandatory. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a creative professional a crafted malicious image or catalog file disguised as a client deliverable or stock photo. When the victim opens the file in Lightroom Classic (version ≤15.4.1), the out-of-bounds write vulnerability in the file parser is triggered, resulting in arbitrary code execution under the victim's user account. … |
| Remediation | The primary fix is to upgrade Adobe Lightroom Classic to version 15.5, which Adobe confirmed as the patched release per advisory APSB26-94 (https://helpx.adobe.com/security/products/lightroom/apsb26-94.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Issue mandatory security alert to all Lightroom Classic users restricting file-opening to trusted sources only; enable endpoint monitoring for suspicious Lightroom child-process spawning and unusual file-system writes. …
