{"id":"CVE-2026-48997","summary":"e107: Command Injection via shell expansion in ImageMagick resize destination path","details":"e107 is a content management system (CMS). Versions  2.3.5 and earlier contain a command injection vulnerability in the ImageMagick resize destination path. In resize_image(), the source path is escaped with escapeshellarg(), but the destination path is inserted inside raw double quotes in the convert command; in the submit-news upload flow, that destination filename includes the first six characters of user-controlled news title input. Because the title filter removes literal spaces but not tab characters, and shell expansions such as $(...) and backticks can survive into the quoted destination argument, /bin/sh -c may evaluate attacker-controlled input. Exploitation is possible only when all of the following non-default settings are enabled: resize_method=ImageMagick, subnews_attach=1, upload_enabled=1, subnews_resize is numeric between 30 and 5000, and the attacker is a non-admin in classes permitted by both subnews_class and upload_class. This issue has been fixed in version 2.3.6.","aliases":["GHSA-3j33-c9v4-4p42"],"modified":"2026-07-15T01:49:11.834972747Z","published":"2026-06-17T21:42:59.679Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48997.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-78"]},"references":[{"type":"WEB","url":"https://github.com/e107inc/e107/releases/tag/v2.3.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48997.json"},{"type":"ADVISORY","url":"https://github.com/e107inc/e107/security/advisories/GHSA-3j33-c9v4-4p42"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48997"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/e107inc/e107","events":[{"introduced":"0"},{"fixed":"02d94125c48909201cfc1950b439724956471fe7"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.3.6"}]}}],"versions":["v2.3.5","v2.3.4","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.3.0-rc1","v2.2.1","v2.2.0","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.0-beta1","v2.0alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48997.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:H"}]}
