CVE-2026-76191: Adobe Animate Code Injection RCE Vulnerability

CVE-2026-76191 is a code injection vulnerability in Adobe Animate that enables arbitrary code execution in the current user context. Attackers can exploit this by tricking users into opening malicious files. This article covers technical details, affected versions, exploitation risks, and recommended mitigation strategies.

CVE-2026-76191 Overview

CVE-2026-76191 is a code injection vulnerability [CWE-94] affecting Adobe Animate. The flaw stems from improper control of code generation during file processing. A low-privileged local attacker can execute arbitrary code in the context of the current user by convincing a victim to open a malicious file. Successful exploitation changes the security scope, meaning impact extends beyond the vulnerable component to affect other resources under the user's authority. Adobe published the corresponding security bulletin APSB26-132 on September 8, 2026.

Critical Impact
Arbitrary code execution in the context of the current user, with high confidentiality, integrity, and availability impact following user interaction with a crafted Animate file.

Affected Products

Adobe Animate (refer to the Adobe Animate Security Advisory for specific affected versions)

Technical Details for CVE-2026-76191

Vulnerability Analysis

Adobe Animate improperly controls the generation of code when parsing an attacker-crafted project or asset file. Processing this file causes the application to interpret attacker-controlled input as executable code. The resulting execution runs with the privileges of the user who opened the file. Because the CVSS scope is changed, the impact can extend beyond the Animate process boundary to resources managed by other authorities on the endpoint.

The vulnerability requires user interaction and local access, which aligns with a typical file-format weaponization workflow. Attackers commonly deliver malicious project files via phishing, shared design repositories, or supply-chain compromise of third-party asset libraries.

Root Cause

The underlying weakness is classified as Improper Control of Generation of Code [CWE-94]. Animate accepts input that is later incorporated into code that the application generates or evaluates during file load, without sufficient validation or sandboxing. This design permits attacker-supplied data to influence the code path that Animate ultimately executes.

Attack Vector

The attack vector is local and requires user interaction. An attacker with low privileges crafts an Animate file containing malicious payload data. The victim opens the file inside Adobe Animate, which then generates and executes attacker-controlled code. No network access to the target is required, and no elevated privileges are needed to trigger the flaw.

No public proof-of-concept or in-the-wild exploitation has been reported at the time of publication. Refer to the Adobe Animate Security Advisory for vendor-supplied technical context.

Detection Methods for CVE-2026-76191

Indicators of Compromise

Unexpected child processes spawned by Animate.exe, particularly shells (cmd.exe, powershell.exe), scripting hosts (wscript.exe, cscript.exe), or rundll32.exe.
Adobe Animate project files (.fla, .xfl) received via email, chat, or downloaded from untrusted sources.
New or modified files in user-writable persistence locations (Startup folders, HKCU\Software\Microsoft\Windows\CurrentVersion\Run) shortly after opening an Animate file.
Outbound network connections initiated by Animate or its child processes to previously unseen hosts.

Detection Strategies

Deploy EDR rules that flag process-tree anomalies where Animate is the parent of interpreters or living-off-the-land binaries.
Correlate file-open telemetry for Animate project files with subsequent process, file, and network events on the same host.
Alert on Animate processes writing executables, DLLs, or scripts to disk outside of standard project directories.

Monitoring Recommendations

Track installed Adobe Animate versions across the fleet and flag hosts running builds prior to the APSB26-132 patch.
Ingest endpoint process, file, and DNS telemetry into a centralized data lake to enable retrospective hunts once further indicators emerge.
Monitor email and collaboration platforms for inbound Animate project files from external senders.

How to Mitigate CVE-2026-76191

Immediate Actions Required

Apply the security update referenced in Adobe bulletin APSB26-132 to all systems running Adobe Animate.
Instruct users not to open Animate project files received from untrusted or unverified sources.
Restrict Animate installations to users with a documented business need and remove the software from systems where it is not required.

Patch Information

Adobe released fixed versions of Animate alongside advisory APSB26-132. Administrators should consult the Adobe Animate Security Advisory for the exact patched version numbers and download locations, then deploy the update through Creative Cloud or existing software distribution tooling.

Workarounds

Block or quarantine Animate project files (.fla, .xfl) at the email gateway until patches are deployed.
Enforce least privilege so that users running Animate do not hold local administrator rights, reducing the blast radius of code execution.
Use application allowlisting to prevent Animate from launching interpreters or unsigned executables.

bash

# Example: query installed Animate version via PowerShell
Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
  Where-Object { $_.DisplayName -like 'Adobe Animate*' } |
  Select-Object DisplayName, DisplayVersion, InstallLocation
