CVE-2026-47952 is a heap-based buffer overflow vulnerability affecting Adobe Acrobat Reader versions 24.001.30365, 26.001.21651, and earlier. The vulnerability allows an attacker to execute arbitrary code in the context of the current user upon opening a malicious file. Exploitation requires user interaction. The CVSS 3.1 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. No official patch or remediation level has been published yet, and no known exploits are reported in the wild.

Successful exploitation can lead to arbitrary code execution with the privileges of the current user, potentially compromising confidentiality, integrity, and availability of the affected system. Since user interaction is required, the risk is limited to scenarios where a user opens a malicious file.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution when opening files from untrusted sources and consider applying any available workarounds or security controls recommended by Adobe once the advisory is published.
