CVE-2023-25871

Code execution via stale SVG object access

Published Mar 27, 2023 · Updated Mar 5, 2025

Use-after-free in SVG parsing in Adobe Substance 3D Stager 2.0.0 and earlier allows remote attackers to execute code via a crafted file. The parser operates on an SVG object without first validating that the object still exists, leaving freed memory in use. Exploitation requires a victim to visit a malicious page or open the file, and code runs in the current process under the current user's privileges.
