Lifecycle Timeline
2DescriptionCVE.org
Lightroom Classic is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AnalysisAI
Out-of-bounds write in Adobe Lightroom Classic versions up to and including 15.4.1 allows arbitrary code execution in the context of the logged-in user when a specially crafted file is opened. Adobe's PSIRT reported the issue under advisory APSB26-94, and the ENISA EUVD tracks it as EUVD-2026-56829. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open a malicious file using an affected version of Lightroom Classic (15.4.1, 15.4, 15.3.1, 15.3, 15.2.1, or 15.2). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.8 (High) appropriately reflects the high C/I/A triad tempered by local attack vector and mandatory user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious file - such as a specially structured image or Lightroom catalog - and delivers it to a target via phishing email, a compromised file-sharing link, or a trojanized download. When the victim opens the file in an affected version of Lightroom Classic, the malformed content triggers the out-of-bounds write during parsing, corrupting memory in a way that redirects execution flow to attacker-controlled code running under the victim's user account. … |
| Remediation | The primary fix is to upgrade Adobe Lightroom Classic to version 15.5, confirmed as the patched release by Adobe 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, conduct a full inventory of systems running Adobe Lightroom Classic up to version 15.4.1 and isolate affected machines from production networks until a patch is released. …
