{"id":"CVE-2026-41247","summary":"elFinder: Command injection in resize background color parameter when using ImageMagick CLI","details":"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.","aliases":["GHSA-8q4h-8crm-5cvc"],"modified":"2026-08-12T03:51:18.294283944Z","published":"2026-04-23T18:47:57.558Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41247.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41247.json"},{"type":"ADVISORY","url":"https://github.com/Studio-42/elFinder/security/advisories/GHSA-8q4h-8crm-5cvc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41247"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/studio-42/elfinder","events":[{"introduced":"0"},{"fixed":"5e463d1384972dffcb736ad3c94f35af10656ca2"}],"database_specific":{"cpe":"cpe:2.3:a:std42:elfinder:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.1.67"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["2.1.66","2.1.65","2.1.64","2.1.63","2.1.62","2.1.61","2.1.60","2.1.59","2.1.58","2.1.57","2.1.56","2.1.55","2.1.54","2.1.53","2.1.52","2.1.51","2.1.50","2.1.49","2.1.48","2.1.47","2.1.46","2.1.45","2.1.44","2.1.43","2.1.42","2.1.41","2.1.40","2.1.39","2.1.38","2.1.37","2.1.36","2.1.35","2.1.34","2.1.33","2.1.32","2.1.31","2.1.30","2.1.29","2.1.28","2.1.27","2.1.26","2.1.25","2.1.24","2.1.23","2.1.22","2.1.21","2.1.20","2.1.19","2.1.18","2.1.17","2.1.16","2.1.15","2.1.14","2.1.13","2.1.12","2.1.11","2.1.10","2.1.9","2.1.8","2.1.7","2.1.6","2.1.5","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41247.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
