This vulnerability, classified as CWE-20 (Improper Input Validation), affects versions prior to 7.1.2-11.  The vulnerability allows for remote unauthenticated attackers to cause a denial of service, or potentially remote code execution.  The issue stems from a failure to properly validate user-supplied input, which could lead to unexpected behavior or memory corruption within the application. Successful exploitation of this vulnerability could have severe consequences, including the compromise of sensitive data or complete system takeover. The Government Technology Agency of Singapore Cyber Security Group (GovTech CSG) reported this vulnerability.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker crafts a malicious image with specially crafted metadata or pixel data.\u003c/li\u003e\n\u003cli\u003eThe attacker hosts the malicious image on a web server or delivers it via email/messaging.\u003c/li\u003e\n\u003cli\u003eThe user downloads or receives the malicious image on their Android device.\u003c/li\u003e\n\u003cli\u003eThe Android device uses Android-ImageMagick7 to process the image (e.g., displaying the image in a gallery app, using it as an avatar, or processing it in a third-party application that relies on the library).\u003c/li\u003e\n\u003cli\u003eAndroid-ImageMagick7 fails to properly validate the malicious image data.\u003c/li\u003e\n\u003cli\u003eDue to the improper input validation, the application may crash, enter an infinite loop, or execute arbitrary code injected by the attacker.\u003c/li\u003e\n\u003cli\u003eIf code execution is achieved, the attacker can gain control of the application's context and potentially escalate privileges on the Android device.\u003c/li\u003e\n\u003cli\u003eThe attacker can then access sensitive data, install malware, or perform other malicious activities.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-4755 can have significant repercussions. An attacker could potentially achieve remote code execution, gaining unauthorized access to sensitive data, or even compromising the entire Android device. Given the widespread use of Android-ImageMagick7, a successful exploit could impact a large number of users across various sectors.
