CVE-2025-54194 Overview
CVE-2025-54194 is an out-of-bounds read vulnerability in Adobe Substance 3D Painter versions 11.0.2 and earlier. The flaw resides in file parsing logic and can disclose sensitive process memory when a victim opens a crafted file. Adobe published details in security bulletin APSB25-77. The issue is classified under CWE-125: Out-of-bounds Read and requires user interaction to exploit. No public proof-of-concept or in-the-wild exploitation has been reported.
Critical Impact
Successful exploitation leaks sensitive memory contents from the Substance 3D Painter process, potentially exposing data useful for further attacks such as ASLR bypass.
Affected Products
- Adobe Substance 3D Painter 11.0.2
- Adobe Substance 3D Painter, all prior versions
- Windows and macOS builds distributed through Adobe Creative Cloud

Technical Details for CVE-2025-54194
Vulnerability Analysis
The vulnerability is an out-of-bounds read in a file parser used by Substance 3D Painter. When the application processes a malformed asset or project file, it reads past the bounds of an allocated buffer. The read operation returns adjacent memory contents to the parsing routine, which can then surface those bytes through application state or output. Attack complexity is low, but exploitation requires the victim to open the malicious file locally.
The impact is limited to confidentiality. There is no direct integrity or availability effect according to the CVSS vector, and no elevation of privilege occurs. Leaked bytes may include pointers, heap metadata, or fragments of previously processed files, which can support secondary exploitation chains against companion memory-corruption bugs.
Root Cause
The root cause is missing or incorrect bounds checking on a length or offset field parsed from an untrusted file. The parser trusts attacker-controlled sizing values and reads memory relative to an internal buffer without validating that the resulting address lies within allocation limits. This is a canonical [CWE-125] pattern in binary asset loaders.
Attack Vector
Exploitation requires local file delivery and user interaction. An attacker crafts a malicious Substance 3D project, texture, or asset file and delivers it through email, chat, a shared repository, or a downloaded asset pack. The victim opens the file in Substance 3D Painter 11.0.2 or earlier, triggering the vulnerable parsing path and disclosing memory to attacker-influenced structures.
No verified public exploit code exists for CVE-2025-54194. Refer to the Adobe Security Update APSB25-77 for vendor-supplied technical context.
Detection Methods for CVE-2025-54194
Indicators of Compromise
- Unexpected crashes or exception logs from Adobe Substance 3D Painter.exe shortly after opening third-party asset files.
- Substance 3D Painter processes reading files from unusual paths such as browser download directories, email attachment caches, or removable media.
- Substance 3D Painter versions 11.0.2 or earlier reported by software inventory on endpoints handling untrusted 3D assets.
Detection Strategies
- Inventory installed Substance 3D Painter builds and flag any version at or below 11.0.2 as vulnerable.
- Correlate file-open telemetry with process crashes or memory faults in the Painter process to surface likely exploitation attempts.
- Alert on Substance 3D Painter opening files that arrived from external sources within the last 24 hours.
Monitoring Recommendations
- Ingest endpoint process, file, and crash telemetry into a centralized data lake for retroactive hunting against known-bad asset hashes.
- Monitor egress traffic from workstations running Substance 3D Painter for anomalous outbound transfers following the opening of untrusted files.
- Track distribution of .spp, .sbsar, and related asset files across collaboration platforms to identify suspicious sources.
How to Mitigate CVE-2025-54194
Immediate Actions Required
- Update Adobe Substance 3D Painter to the version listed as fixed in Adobe Security Bulletin APSB25-77.
- Restrict opening of Substance 3D asset files received from untrusted or unverified sources.
- Communicate the risk to 3D content creators and require validation of asset provenance before opening files.
Patch Information
Adobe addressed CVE-2025-54194 in the security update documented in APSB25-77. Users of Substance 3D Painter 11.0.2 and earlier must upgrade to the fixed release distributed through Adobe Creative Cloud. Enterprises using managed Creative Cloud deployments should push the update through the Adobe Admin Console.
Workarounds
- Block or quarantine inbound Substance 3D project and asset files at email and web gateways until patching is complete.
- Isolate 3D content workstations from sensitive network segments to limit the value of any memory disclosed to an attacker.
- Enforce application allowlisting to ensure only signed, current Substance 3D Painter binaries execute on managed endpoints.
