The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires the victim to manually open an attacker-crafted malicious file in Photoshop Desktop (UI:R) on a vulnerable build - Photoshop at or below version 26.11.7, or at or below 27.10 per the EUVD data. The attack vector is local (AV:L): the attacker cannot trigger the flaw over a network and must get the malicious file onto the victim's system and induce them to open it. Although PR:N indicates no prior authentication to the application is needed, the mandatory user interaction and local-only vector are the principal limiting factors; code executes only with the opening user's privileges (S:U, no privilege escalation). No special non-default configuration is indicated in the available data.

Impact

This is a genuine but operationally moderate priority. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U) confirms a local attack vector requiring user interaction - the victim must open a malicious file - not remote unauthenticated exploitation, which caps the base score at 7.8 (High) despite full C:H/I:H/A:H impact. The CWE-787 out-of-bounds write yielding arbitrary code execution in the current user's context is a classic memory-corruption RCE pattern. No EPSS score, CISA KEV listing, POC, or SSVC decision data was provided in the input, so exploitation probability and automatability cannot be quantified. There is no public exploit identified at time of analysis and no evidence of active exploitation; the file-open user-interaction requirement and local vector make this better suited to targeted social-engineering (malicious .PSD/image delivered via email or download) than mass, automatable exploitation. Treat as a standard-urgency patch for workstations handling untrusted files rather than an emergency, but note that Photoshop's large creative-user base and routine opening of externally-sourced files raise practical exposure.

Exploit ScenarioDerived

An attacker crafts a malicious image/document file that triggers the out-of-bounds write when parsed by Photoshop Desktop, then delivers it to a victim via email, a shared drive, or a download disguised as a legitimate design asset. When the victim opens the file, the memory corruption executes attacker-controlled code with the victim's privileges. No public exploit is identified at time of analysis; the local vector and mandatory user interaction (UI:R) mean the attack hinges on social engineering rather than remote triggering.

AnalysisAIv1 – Oct 13, 2026

Out-of-bounds write in Adobe Photoshop Desktop running builds at or below 26.11.7 (and at or below 27.10 per ENISA EUVD data) allows an attacker to execute arbitrary code in the context of the user who opens a crafted file. Because exploitation requires the victim to manually open a malicious file on their own system, the attack vector is local-only and depends on user interaction, and any code that runs inherits only the opening user's privileges (no privilege escalation). This is a genuine but operationally moderate-priority issue: no public exploit code and no confirmed active exploitation were identified at time of analysis, and the local plus user-interaction prerequisites materially reduce real-world risk.

RemediationAI

Apply the Photoshop update identified in Adobe security bulletin apsb26-158 (https://www.adobe.com/trust/security/products/photoshop/apsb26-158.html) as the primary fix; because the exact patched build numbers are not present in the supplied data, confirm them from that bulletin before validating remediation, and note that any build at or below 26.11.7 or 27.10 is affected. Distribution is normally through the Creative Cloud desktop app, so enabling automatic updates or forcing an update check on every Photoshop installation - including isolated creator workstations that rarely update - is the practical path to closure. Where immediate upgrading is not possible, compensating controls must focus on the file-open prerequisite: block inbound email/web downloads of untrusted image and document files and strip or quarantine them at the gateway, and for high-risk review workflows open untrusted files in a disposable VM or an isolated low-privilege Windows/macOS account so a successful write primitive cannot reach production data (trade-off: added friction and no protection if the user opens the file in their normal session). Running Photoshop as a standard, non-administrator user limits the blast radius of any successful exploit, but does not prevent code execution, and no configuration flag in the available data disables the vulnerable parsing path.

Technical ContextAI · show details

The flaw is a CWE-787 out-of-bounds write, a memory-corruption class in which the application writes data past the boundaries of an allocated buffer, typically while parsing a malformed image or document structure. Successful corruption of adjacent memory can be shaped into controlled code execution in the Photoshop process, which is why Adobe's PSIRT (psirt@adobe.com) tags the issue as RCE, buffer overflow, and memory corruption. The CVSS:3.1 vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H confirms the mechanics: the attacker cannot reach the target over a network (AV:L), no prior authentication to Photoshop is needed (PR:N), but the victim must open the malicious file (UI:R), and the scope is unchanged (S:U) so impact is confined to the Photoshop process under the current user's rights. No CPE identifiers or additional weakness chains were supplied in the source data; the authoritative vendor record is the Adobe Photoshop security bulletin referenced under NVD.

DescriptionCVE.org

Photoshop Desktop 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.

Executive ViewAI

Why It Matters

Adobe Photoshop Desktop versions at or below 26.11.7 and 27.10 carry a high-severity code-execution flaw that can affect the user who opens a specially crafted file locally. Creative, design, and other teams that handle external Photoshop files are the primary exposure group, with potential for data compromise, endpoint disruption, or follow-on activity using the user's credentials. Leadership should prioritize endpoint inventory, user awareness, and interim file-handling controls while monitoring for a vendor-released patch, as no public exploit identified at time of analysis and no vendor-released patch identified at time of analysis.

Business Impact: Medium
Compensating Controls

No vendor-released patch identified at time of analysis; apply interim mitigations including user training on not opening untrusted Photoshop files, email and web gateway attachment blocking or sandboxing, application allowlisting, least-privilege execution, endpoint detection and response monitoring for suspicious Photoshop child processes, and network/file-share restrictions on untrusted Photoshop content.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
