Adobe After Effects versions 25.6 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing disruption to services. Exploitation of this issue requires user interaction in that a victim must open a malicious file. With a CVSS score of 5.5, this vulnerability is classified as medium severity.
Risk to organizations includes service disruption due to application crashes, impacting productivity and potentially leading to loss of data during critical tasks. Although the exploitation requires user interaction, it is crucial for organizations to understand the potential consequences of this vulnerability.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. Continuous monitoring and user education regarding the dangers of opening untrusted files can further help reduce the attack surface.
The vulnerability was published on February 10, 2026. The analysis indicates that it has not been actively exploited in the wild, which provides a window for organizations to apply necessary updates before it becomes a target.
Vulnerability Details
This vulnerability allows for a denial-of-service condition. The affected product is Adobe After Effects, with all versions prior to 25.6.4 being vulnerable. The vulnerability has a CWE classification of CWE-476 (NULL Pointer Dereference), indicating that the application does not handle null pointers correctly.
Technical Analysis
The root cause of the vulnerability stems from improper handling of null pointers within the application code. This deficiency can be exploited when an attacker convinces a user to open a specially crafted file, triggering the null pointer dereference and causing the application to crash.
The attack vector for this vulnerability is local, meaning that the attacker must have access to the user's machine, typically through social engineering tactics. The complexity of the attack is low, as it merely requires the user to open a malicious file.
No special privileges are required for the attack to succeed; however, user interaction is mandatory. The impact is significant in that it results in high availability impact, causing the application to crash, which can disrupt workflows.
Risk & Impact Analysis
Organizations should be aware that the risk associated with this vulnerability includes potential service disruptions, which can affect business operations. The medium CVSS score suggests that while the vulnerability is not critical, it should not be ignored.
The blast radius for exploitation could extend to any user of After Effects versions 25.6 and earlier. Organizations should assess their deployment of this software and prioritize remediation efforts accordingly.
Given the absence of active exploitation reports, organizations still need to remain vigilant and proactive. The exploitation timeline indicates that immediate remediation is not yet a priority, but this could change if the vulnerability becomes widely known.
