An attacker can exploit this vulnerability to achieve arbitrary code execution in the context of the current user. The exploit requires user interaction, specifically, the victim must open a specially crafted malicious file in After Effects. This vulnerability poses a significant risk as successful exploitation could allow an attacker to compromise the user\u0026rsquo;s system.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker crafts a malicious After Effects project file.\u003c/li\u003e\n\u003cli\u003eThe attacker distributes the malicious file to a target victim, potentially via email or other file-sharing methods.\u003c/li\u003e\n\u003cli\u003eThe victim opens the malicious After Effects project file in a vulnerable version (\u0026lt;=26.0, 25.6.4).\u003c/li\u003e\n\u003cli\u003eThe vulnerable application attempts to parse the malicious file.\u003c/li\u003e\n\u003cli\u003eDue to the buffer overflow in the parsing logic, the attacker can overwrite parts of the stack with controlled values.\u003c/li\u003e\n\u003cli\u003eThe code execution is redirected to the attacker\u0026rsquo;s payload.\u003c/li\u003e\n\u003cli\u003eThe attacker executes arbitrary code in the context of the user.\u003c/li\u003e\n\u003cli\u003eThe attacker can then install malware, steal data, or perform other malicious actions.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-34690 allows an attacker to execute arbitrary code on the victim\u0026rsquo;s system.
