Prior to version 20.17.0, PHP functions such as `getimagesize()`, `file_exists()`, and `is_readable()` can trigger deserialization when processing `phar://` stream wrapper paths. OpenMage LTS uses these functions with potentially controllable file paths during image validation and media handling. An attacker who can upload a malicious phar file (disguised as an image) and trigger one of these functions with a `phar://` path can achieve arbitrary code execution. Version 20.17.0 patches the issue."}], "lastModified": "2026-04-23T17:47:24.977", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openmage:magento:*:*:*:*:lts:*:*:*", "vulnerable": true, "matchCriteriaId": "D3D78A44-3FCF-4E81-9A3C-A66A99CC489D", "versionEndExcluding": "20.17.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
