An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-25524 exists.\n\nAffected packages and fixed versions:\n- openmage/magento-lts (Packagist): affected all versions; fixed in 20.17.0\n- openmage/magento-lts (Packagist): affected all versions; fixed in 20.17.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-25524/ (Markdown: https://insights.sbomify.com/CVE-2026-25524/index.md)","id":"CVE-2026-25524","markdown":"https://insights.sbomify.com/CVE-2026-25524/index.md","name":"CVE-2026-25524","record":{"aliases":["GHSA-fg79-cr9c-7369"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Magento LTS e-commerce","requires_auth":"none","summary":"Attackers can achieve remote code execution by uploading malicious phar files disguised as images, triggering unsafe deserialization in OpenMage LTS.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"magento","vendor":"openmage"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. 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.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":"2026-09-04","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-04T10:46:00Z","kind":"github_poc","ref":"https://github.com/Emily-0309/unit-01-severity-vs-risk-reflection","stars":0,"title":"cve-2026-25524  Holds no customer payment data, no monitoring in place, monitored 24/7 The CVSS score is technically serious, but it doesn't tell how exposed it is, weather our existing defenses would stop or contain an attack.
