{"id":"CVE-2025-47786","state":"PUBLISHED","title":"Emlog vulnerable to Stored Cross-site Scripting","description":"Emlog is an open source website building system. Version 2.5.13 has a stored cross-site scripting vulnerability that allows any registered user to construct malicious JavaScript, inducing all website users to click. In `/admin/comment.php`, the parameter `perpage_num` is not validated and is directly stored in the `admin_commend_perpage_num` field of the `emlog_options` table in the database. Moreover, the output is not filtered, resulting in the direct output of malicious code. As of time of publication, it is unclear if a patch exists.","publishedAt":"2025-05-15T19:33:24.271Z","updatedAt":"2025-05-19T14:40:12.463Z","severity":{"score":1.9,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:P","source":"GitHub_M"},"assigner":"GitHub_M","products":["emlog emlog"],"affected":[{"vendor":"emlog","product":"emlog","versions":[{"version":"= 2.5.13","status":"affected"}]}],"references":["https://github.com/emlog/emlog/security/advisories/GHSA-82qc-9vg7-2c6c"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:09:23.771Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/47xxx/CVE-2025-47786.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-47786","state":"PUBLISHED","datePublished":"2025-05-15T19:33:24.271Z","dateUpdated":"2025-05-19T14:40:12.463Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-05-09T19:49:35.621Z"},"containers":{"cna":{"title":"Emlog vulnerable to Stored Cross-site Scripting","descriptions":[{"lang":"en","value":"Emlog is an open source website building system.
