CVE-2026-48346: Adobe Animate RCE Vulnerability

CVE-2026-48346 Overview

CVE-2026-48346 is an Untrusted Search Path vulnerability [CWE-426] affecting Adobe Animate. An attacker can achieve arbitrary code execution in the context of the current user when a victim opens a malicious file. The flaw carries a scope change, meaning successful exploitation impacts resources beyond the vulnerable component itself. Adobe published the fix in security bulletin APSB26-83. Exploitation requires local access and user interaction, but no elevated privileges are needed to place the malicious payload alongside a crafted project file.

Critical Impact
Successful exploitation allows arbitrary code execution under the current user context, enabling attackers to install programs, modify data, or create new accounts with the victim's privileges.

Affected Products

Adobe Animate (see APSB26-83 for affected versions)
Microsoft Windows platforms running Adobe Animate
Apple macOS platforms running Adobe Animate

Technical Details for CVE-2026-48346

Vulnerability Analysis

The vulnerability stems from Adobe Animate resolving executable or library dependencies through an untrusted search path. When Animate loads supporting components, the process searches directories that an unprivileged local attacker can write to. An attacker who places a malicious binary in one of these directories can hijack the load order and execute code inside the Animate process.

The attack requires a victim to open a malicious file, which triggers the search path resolution. Because scope is changed, the executed code can affect resources managed by a different security authority than the vulnerable component itself. This typically corresponds to breaking out of the application sandbox or influencing files owned by the operating system user.

Root Cause

Adobe Animate does not fully qualify the paths used when loading auxiliary modules, libraries, or helper executables. Windows and macOS both consult directory search orders that include the current working directory or user-writable locations. When Animate opens a project, it inherits those search semantics, allowing attacker-controlled binaries to be loaded ahead of legitimate ones.

Attack Vector

The attack vector is local and requires user interaction. A typical exploitation chain includes:

The attacker crafts a malicious Animate project file bundled with a rogue DLL or dylib matching a name Animate loads.
The victim receives the archive through email, download, or removable media and extracts it into a single directory.
The victim double-clicks the project file, launching Animate with the malicious directory as the working directory.
Animate loads the attacker-supplied binary from the untrusted search path, executing code as the current user.

See the Adobe Security Advisory APSB26-83 for technical details on the affected load paths.

Detection Methods for CVE-2026-48346

Indicators of Compromise

Unexpected DLL or dylib files co-located with .fla, .xfl, or other Animate project files delivered from external sources.
Adobe Animate processes (Animate.exe on Windows, Adobe Animate on macOS) spawning child processes such as cmd.exe, powershell.exe, or bash.
Module load events showing Animate loading libraries from user-writable directories rather than the Adobe installation path.

Detection Strategies

Monitor image and module load telemetry to flag Animate loading modules outside its installation directory tree.
Alert on Animate processes making outbound network connections to non-Adobe destinations shortly after opening a project file.
Baseline the legitimate module set for Animate and identify deviations that indicate untrusted binaries being loaded.

Monitoring Recommendations

Enable EDR module-load and process-creation logging on workstations where Animate is installed.
Correlate file-write events for .dll or .dylib files in the same directory as recently opened project files.
Review email and web proxy logs for archives containing Animate project files paired with executable binaries.

How to Mitigate CVE-2026-48346

Immediate Actions Required

Apply the Adobe Animate updates referenced in security bulletin APSB26-83 on all Windows and macOS endpoints.
Instruct users to open Animate project files only from trusted sources and never from extracted archives containing unknown binaries.
Restrict user permissions to prevent writing executable files to shared or working directories used to launch Animate.

Patch Information

Adobe released fixes as part of security bulletin APSB26-83. Consult the Adobe Security Advisory APSB26-83 for the specific patched versions and download locations for both Windows and macOS installers.

Workarounds

Open suspicious .fla or .xfl files inside an isolated virtual machine without network access.
Extract archived project files into a dedicated directory reviewed for unexpected .dll or .dylib payloads before opening.
Apply application allowlisting policies that prevent Animate from loading unsigned modules from user directories.

bash

# Windows: identify unsigned DLLs adjacent to Animate project files
Get-ChildItem -Path 'C:\Users\*\Downloads' -Include *.dll -Recurse |
  ForEach-Object { Get-AuthenticodeSignature $_.FullName } |
  Where-Object { $_.Status -ne 'Valid' }
