Adobe After Effects: Out-of-bounds write allows code execution
Summary
Adobe After Effects contains an out-of-bounds write vulnerability (CWE-787, CVE-2026-113517) that can lead to arbitrary code execution. The code runs with the rights of the logged-in user. Exploitation requires a victim to open a malicious file in After Effects, so the risk comes mainly from project or media files received from untrusted sources.
Affected
- Adobe After Effects 26.5 and earlier (Windows and macOS)
- Adobe After Effects 25.6.6 and earlier (Windows and macOS)
Fixed in
- Adobe After Effects 26.5.3 (for the 26.x line)
- Adobe After Effects 27.0 (for the 25.6.x line)
Workaround
Unknown. No vendor workaround is published for this CVE. Interim measures until the update is installed:
- Do not open project or media files from untrusted sources.
- Restrict which users can receive such files.
- Keep the Creative Cloud desktop app set to automatic updates.
Exploitation
- Adobe states it is not aware of any exploits in the wild for the issues in bulletin APSB26-100.
- CISA SSVC assessment: exploitation none, automatable no, technical impact total.
- CISA KEV status not verified.
- Public proof of concept: unknown.
Our recommendation
- Update After Effects to 26.5.3 or 27.0, depending on the installed version, on all workstations that have it installed.
- Prioritise machines that open files from external parties, such as freelancers or email attachments.
- Instruct users not to open unexpected project or media files.
- Monitor for public proof-of-concept code and for NVD analysis and KEV updates.
