2DescriptionCVE.org
After Effects is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AnalysisAI
Arbitrary code execution in Adobe After Effects arises from an out-of-bounds write (CWE-787) triggered when a victim opens a maliciously crafted project or media file, running attacker code with the privileges of the current user. Adobe self-reported the flaw in advisory APSB26-78; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. The CVSS 7.8 (High) rating reflects high confidentiality, integrity, and availability impact but is gated by required user interaction and local file delivery.
