{"id":"CVE-2026-21433","state":"PUBLISHED","title":"Emlog vulnerable to Server-Side Request Forgery (SSRF)","description":"Emlog is an open source website building system. Versions up to and including 2.5.19 are vulnerable to server-side Out-of-Band (OOB) requests / SSRF via uploaded SVG files. An attacker can upload a crafted SVG to http[:]//emblog/admin/media[.]php which contains external resource references. When the server processes/renders the SVG (thumbnailing, preview, or sanitization), it issues an HTTP request to the attacker-controlled host. Impact: server-side SSRF/OOB leading to internal network probing and potential metadata/credential exposure. As of time of publication, no known patched versions are available.","publishedAt":"2026-01-02T19:00:22.611Z","updatedAt":"2026-01-05T20:37:52.330Z","severity":{"score":7.7,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["emlog emlog"],"affected":[{"vendor":"emlog","product":"emlog","versions":[{"version":"<= 2.5.19","status":"affected"}]}],"references":["https://github.com/emlog/emlog/security/advisories/GHSA-6rwr-c8hc-mjj4"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/21xxx/CVE-2026-21433.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-21433","state":"PUBLISHED","datePublished":"2026-01-02T19:00:22.611Z","dateUpdated":"2026-01-05T20:37:52.330Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-12-29T03:00:29.275Z"},"containers":{"cna":{"title":"Emlog vulnerable to Server-Side Request Forgery (SSRF)","descriptions":[{"lang":"en","value":"Emlog is an open source website building system.
