ImageMagick before 7.1.2-26 contains a policy bypass vulnerability in the APNG encoder and external delegates due to missing validation checks. Attackers can write files to disallowed paths by bypassing configured policy restrictions through the APNG encoding process.

A flaw was found in ImageMagick. This vulnerability allows attackers to bypass configured policy restrictions through the APNG (Animated Portable Network Graphics) encoding process. By exploiting missing validation checks in the APNG encoder and external delegates, an attacker can write files to disallowed paths. This could lead to unauthorized file creation or modification, potentially impacting system integrity.
