An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41247 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- studio-42/elfinder (Packagist): affected all versions; fixed in 2.1.67\n- studio-42/elfinder (Packagist): affected all versions; fixed in 2.1.67\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-2026-41247/ (Markdown: https://insights.sbomify.com/CVE-2026-41247/index.md)","id":"CVE-2026-41247","markdown":"https://insights.sbomify.com/CVE-2026-41247/index.md","name":"CVE-2026-41247","record":{"aliases":["GHSA-8q4h-8crm-5cvc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Web file manager","requires_auth":"none","summary":"Attackers can execute arbitrary commands via crafted background color parameters in elFinder when using the ImageMagick CLI backend.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"elfinder","vendor":"std42"}],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.67, elFinder contains a command injection vulnerability in the resize command. The bg (background color) parameter is accepted from user input and passed through image resize/rotate processing. In configurations that use the ImageMagick CLI backend, this value is incorporated into shell command strings without sufficient escaping. An attacker able to invoke the resize command with a crafted bg value may achieve arbitrary command execution as the web server process user. This vulnerability is fixed in 2.1.67.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"elFinder: Command injection in resize background color parameter when using ImageMagick CLI","id":"CVE-2026-41247","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Official Clerk JavaScript SDKs: Middleware-based route protection bypass","id":"CVE-2026-41248"},"packages":[{"ecosystem":"Packagist","fixed":["2.1.67"],"introduced":["0"],"last_affected":[],"package":"studio-42/elfinder","purl":null,"source":"GHSA-8q4h-8crm-5cvc"},{"ecosystem":"Packagist","fixed":["2.1.67"],"introduced":["0"],"last_affected":[],"package":"studio-42/elfinder","purl":"pkg:composer/studio-42/elfinder","source":"GHSA-8q4h-8crm-5cvc"}],"prev":{"headline":"Contour: Lua code injection via Cookie Path Rewrite Policy","id":"CVE-2026-41246"},"products":["elFinder"],"published":"2026-04-23","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2023-52044","kev_date_added":null,"published":"2024-10-31"},{"cvss_score":9.8,"headline":"Studio 42 elFinder vulnerable to Incorrect Access Control","id":"CVE-2024-38909","kev_date_added":null,"published":"2024-07-30"},{"cvss_score":9.8,"headline":"RCE in Studio-42 elFinder on Windows before 2.1.61","id":"CVE-2022-27115","kev_date_added":null,"published":"2022-04-11"},{"cvss_score":9.8,"headline":"elFinder Unrestricted File Upload vulnerability","id":"CVE-2021-43421","kev_date_added":null,"published":"2022-04-07"},{"cvss_score":9.8,"headline":"Multiple vulnerabilities leading to RCE","id":"CVE-2021-32682","kev_date_added":null,"published":"2021-06-14"},{"cvss_score":9.8,"headline":"elFinder command injection vulnerability in the PHP connector","id":"CVE-2019-9194","kev_date_added":null,"published":"2019-02-26"},{"cvss_score":9.1,"headline":"Path Traversal in Studio-42 elFinder through 2.1.60","id":"CVE-2022-26960","kev_date_added":null,"published":"2022-03-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-25","vendors":["Studio-42"]},"summary":"Attackers can execute arbitrary commands via crafted background color parameters in elFinder when using the ImageMagick CLI backend.","url":"https://insights.sbomify.com/CVE-2026-41247/"}
