CVE-2026-47971 is a stack-based buffer overflow vulnerability (CWE-121) in Adobe Media Encoder. Successful exploitation allows an attacker to execute arbitrary code in the context of the current user. The vulnerability requires user interaction, specifically opening a crafted malicious file. The CVSS v3.1 base score is 7.8, indicating high severity with local attack vector, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. No patch or remediation information is currently available, and no known exploits are reported in the wild.

If exploited, this vulnerability could allow an attacker to execute arbitrary code with the privileges of the current user, potentially leading to full compromise of the affected system's confidentiality, integrity, and availability. The requirement for user interaction limits the attack vector to scenarios where a user opens a malicious file.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening files from untrusted sources to avoid triggering this vulnerability.
