CVE-2025-54279 is a Use After Free vulnerability (CWE-416) affecting Adobe Animate versions 23.0.13, 24.0.10, and earlier. Use After Free vulnerabilities occur when a program continues to use memory after it has been freed, leading to undefined behavior that attackers can exploit to execute arbitrary code. In this case, the vulnerability allows an attacker to craft a malicious Animate file that, when opened by a user, triggers the use-after-free condition. This can result in arbitrary code execution within the context of the current user, potentially allowing attackers to compromise the affected system. The vulnerability requires user interaction, meaning the victim must open the malicious file for exploitation to succeed. The CVSS v3.1 score of 7.8 reflects high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or exploits are currently publicly available, but the vulnerability is officially published and reserved since July 2025. Adobe Animate is widely used in multimedia content creation, making this vulnerability significant for creative professionals and organizations relying on this software.

The impact of CVE-2025-54279 is substantial due to its potential for arbitrary code execution, which can lead to full compromise of the affected user's system. Confidentiality is at risk as attackers could access sensitive data; integrity is compromised as attackers could alter files or system configurations; and availability could be disrupted through destructive payloads or system crashes. Since the vulnerability requires user interaction, social engineering or phishing campaigns could be used to deliver malicious Animate files. Organizations with large creative teams or those that exchange Animate files externally are particularly vulnerable. The lack of current public exploits reduces immediate risk but also means attackers may develop exploits once patches are released. The vulnerability's presence in widely used software increases the attack surface globally, potentially affecting a broad range of industries including media, advertising, education, and entertainment.

1. Monitor Adobe’s official channels for patches and apply updates promptly once available to remediate the vulnerability. 2. Until patches are released, restrict the opening of Animate files from untrusted or unknown sources through email filtering and endpoint controls. 3. Implement application whitelisting and sandboxing to limit the execution context of Adobe Animate and reduce the impact of potential exploitation. 4. Educate users about the risks of opening files from unverified sources and train them to recognize phishing attempts that could deliver malicious Animate files. 5. Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior related to Adobe Animate processes. 6. Use network segmentation to isolate systems running Adobe Animate, minimizing lateral movement if exploitation occurs. 7. Regularly back up critical data to enable recovery in case of compromise. 8. Review and harden user privileges to ensure that Adobe Animate runs with the least privilege necessary, limiting the scope of potential damage.
