CVE-2026-48369 Overview
CVE-2026-48369 is an out-of-bounds write vulnerability [CWE-787] in Adobe Premiere Pro. Successful exploitation allows arbitrary code execution in the context of the current user. The flaw requires user interaction: a victim must open a malicious file crafted by the attacker.
Adobe published the fix in security advisory APSB26-76. The vulnerability carries a local attack vector, meaning the malicious file must be delivered to and opened on the target system. No public exploit code or in-the-wild exploitation has been reported at the time of publication.
Critical Impact
Attackers who convince a user to open a crafted media project or asset file can execute arbitrary code with the privileges of the logged-in user, enabling malware installation, credential theft, or lateral movement.
Affected Products
- Adobe Premiere Pro (versions listed in Adobe advisory APSB26-76)
- Windows installations of Adobe Premiere Pro
- macOS installations of Adobe Premiere Pro

Technical Details for CVE-2026-48369
Vulnerability Analysis
The vulnerability is an out-of-bounds write [CWE-787] in the file parsing logic of Adobe Premiere Pro. When the application processes a malformed media, project, or asset file, it writes data past the boundary of an allocated buffer. This corruption of adjacent memory structures can be steered by an attacker to hijack control flow.
Because Premiere Pro handles complex, container-based multimedia formats, parsers frequently rely on length and offset fields taken directly from the file. A crafted file with inconsistent size metadata triggers the write past the buffer boundary. The result is arbitrary code execution under the security context of the user running the application.
Root Cause
The root cause is insufficient validation of size or index values used during memory writes in Premiere Pro's file parsing components. The application trusts attacker-controlled fields when calculating destination offsets, allowing writes outside the intended buffer.
Attack Vector
Exploitation is local and requires user interaction. An attacker must deliver a malicious file to the victim through email, chat, a compromised website, or shared project storage. Opening the file inside Premiere Pro triggers the vulnerable parsing path and executes attacker-supplied code with the current user's privileges.
No authenticated network access to the victim system is required. See the Adobe Security Advisory APSB26-76 for affected version details.
Detection Methods for CVE-2026-48369
Indicators of Compromise
- Unexpected child processes spawned by Adobe Premiere Pro.exe or Adobe Premiere Pro on macOS, such as command shells, powershell.exe, or scripting engines
- Premiere Pro process crashes or Windows Error Reporting entries referencing access violations shortly after opening a project or media file
- Media or project files (.prproj, .mogrt, container formats such as MXF, MOV, MP4) received from untrusted sources and opened outside normal editorial workflows
Detection Strategies
- Alert on Premiere Pro spawning interpreters, LOLBins, or network utilities, which is atypical for a video editing application
- Correlate application crash telemetry with subsequent process creation or outbound network activity from the same user session
- Inspect email and file-sharing gateways for uncommon or malformed multimedia and project files delivered to editorial staff
Monitoring Recommendations
- Enable process creation and image load logging on workstations running Premiere Pro, and forward events to a centralized SIEM
- Monitor for unsigned or newly written executables and DLLs in user-writable directories accessed by the Premiere Pro process
- Track outbound connections initiated by Premiere Pro to non-Adobe destinations, which may indicate post-exploitation command and control
How to Mitigate CVE-2026-48369
Immediate Actions Required
- Apply the updates listed in Adobe Security Advisory APSB26-76 to all systems running Adobe Premiere Pro
- Instruct users to avoid opening Premiere Pro project or media files received from untrusted sources until patching is complete
- Inventory endpoints with Premiere Pro installed and prioritize creative and post-production workstations for immediate remediation
Patch Information
Adobe has released fixed versions of Premiere Pro in advisory APSB26-76. Administrators should use Adobe Creative Cloud desktop application or enterprise deployment tooling to push the updated build. Confirm the installed version matches or exceeds the patched version listed in the advisory before returning systems to normal use.
Workarounds
- Restrict file associations so that untrusted media and project files do not open in Premiere Pro by default
- Run Premiere Pro under standard user accounts rather than administrative accounts to limit the impact of successful exploitation
- Enforce application allowlisting to prevent Premiere Pro from launching unauthorized child processes
- Use email and web filtering to block or sandbox uncommon multimedia container formats delivered from external senders
