{"id":"CVE-2026-57940","details":"HTMLy 3.1.1 contains a Server-Side Request Forgery (SSRF) vulnerability in the RSS feed import functionality. The function get_feed() in system/admin/admin.php passes user-supplied $feed_url directly to file_get_contents() without any validation. An authenticated attacker with administrative privileges can exploit this by entering a crafted URL (e.g., http://dnslog.example.com, file:///etc/passwd, or http://169.254.169.254 in cloud contexts) via Tools -\u003e Import RSS. The server will then make a request to the attacker-controlled target.","modified":"2026-07-15T02:20:32.134855898Z","published":"2026-06-26T13:08:02.485Z","database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57940.json"},"references":[{"type":"WEB","url":"https://github.com/danpros/htmly/blob/c8b7ed9af39a266b256759becf26dba6a59e11e6/system/admin/admin.php#L1549-L1551"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57940.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57940"},{"type":"PACKAGE","url":"https://github.com/danpros/htmly"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/danpros/htmly","events":[{"introduced":"0"},{"last_affected":"dde01601bd9e64eaff695814d03c1f31d9eb8f37"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.1.1"}],"source":"AFFECTED_FIELD"}}],"versions":["3.1.1","v3.1.1","v3.1.0","v3.0.9","v3.0.8","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.9.9","v2.9.8","v2.9.7","v2.9.6","v2.9.5","v2.9.4","v2.9.3","v2.9.2","v2.9.1","v2.9.0","v2.8.9","v2.8.8","v2.8.7","v.2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.9","v2.7.8","v2.7.7","v2.7.6","v2.7.5","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.9","v2.6.8","v2.6.7","v2.6.6","v2.6.5","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.9","v2.5.8","v2.5.7","v2.5.6","v2.5.5","v2.5.4","v2.5.3","v2.5.2","v2.4.1","v2.5.1","v2.5","v2.4","v2.3","v2.2","v2.1","v2.0","v1.9","v1.8","v1.7","v1.6","v1.5","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57940.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/AU:N/R:A/V:D/RE:L/U:Clear"}]}
