{"id":"CVE-2026-104440","summary":"YesWiki before 4.6.7 Blind SSRF via bazarlist API idtypeannonce Parameter","details":"YesWiki before 4.6.7 contains a blind server-side request forgery vulnerability that allows unauthenticated attackers to make arbitrary server-side requests via the idtypeannonce parameter of /api/entries/bazarlist. Because isValidURL() always returns true, attackers can supply internal URLs fetched by curl in loadURLContent() to probe internal networks and reach internal services or metadata endpoints.","aliases":["GHSA-gw65-cpc7-hww6"],"modified":"2026-10-04T02:45:58.360468090Z","published":"2026-10-02T11:38:15.830Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104440.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104440.json"},{"type":"ADVISORY","url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-gw65-cpc7-hww6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104440"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/yeswiki-before-4.6.7-blind-ssrf-via-bazarlist-api-idtypeannonce-parameter"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/yeswiki/yeswiki","events":[{"introduced":"0"},{"fixed":"07120ed8971047f504f7ec78060828f1895f475f"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.6.7"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v4.6.6","v4.6.5","v4.6.4","v4.6.3","v4.6.2","v4.6.0","v4.5.5","v4.5.4","v4.5.3","v4.5.2","v4.5.1","v4.4.3","v4.4.2","v4.4.1","v4.4.0","v4.3.1","v4.3.0","v4.2.2","v4.2.1","v4.2.0","v4.1.5","v4.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-104440.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:N/VI:L/VA:N/SC:L/SI:L/SA:L"}]}
