Summary

CVE-2026-34632 is a high-severity Uncontrolled Search Path Element (CWE-427) vulnerability in Adobe Photoshop Installer. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 19th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-34632 is an Uncontrolled Search Path Element vulnerability (CWE-427) affecting the Adobe Photoshop Installer. This flaw allows arbitrary code execution in the context of the current user by enabling manipulation of the search path the application uses to locate critical resources. The vulnerability carries a CVSS v3.1 base score of 8.2 (AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H) and was published on 2026-04-15.

A low-privileged local attacker can exploit this issue when a user runs the installer, which requires user interaction. By manipulating the search path, the attacker can cause the application to execute unauthorized code, potentially leading to full compromise of the user's session with high confidentiality, integrity, and availability impacts due to the elevated scope (S:C).

For mitigation details, refer to the CWE-427 definition at https://cwe.mitre.org/data/definitions/427.html and the Talos Intelligence advisory TALOS-2025-2274 at https://www.talosintelligence.com/vulnerability_reports/TALOS-2025-2274.

Mitigating Controls (NIST 800-53 r5) AI

Establishes restrictive configuration settings that can define and lock down approved search paths.

Enforces approved authorizations so that only intended actors can place or modify elements in the search path.

Limits privileges so unintended actors cannot write to or control directories in the product's search path.

Restricts logical and physical access to change system configuration, including search-path settings and directories.

finds

Security testing can detect uncontrolled search-path issues but does not prevent them by itself.

mitigates

Restricting software installation reduces the chance that an attacker-controlled path element is introduced into the search path.

mitigates

Secure system architecture and engineering principles require explicit control over search paths and resource locations.

prevents

Secure coding practices directly address the use of fixed or controlled search paths that can be influenced by unintended actors.

prevents

Configuration management can enforce approved search-path settings but does not inherently prevent the weakness.
