The SSRF guard validates a hostname's resolved IP addresses but discards them before the actual HTTP connection is opened, allowing an attacker who controls authoritative DNS to return a public address during validation and a private address during the subsequent independent socket-level DNS resolution, causing the guard to pass while the outbound connection reaches internal infrastructure such as cloud instance metadata endpoints.","publishedAt":"2026-08-19T16:35:53.999Z","updatedAt":"2026-08-21T11:21:04.300Z","severity":{"score":2.3,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["ridafkih keeper.sh"],"affected":[{"vendor":"ridafkih","product":"keeper.sh","defaultStatus":"affected","versions":[{"version":"0","status":"affected","lessThan":"2.18.14","versionType":"semver"}]}],"references":["https://github.com/ridafkih/keeper.sh","https://github.com/ridafkih/keeper.sh/security/advisories/GHSA-mxxg-qffg-j3p6","https://github.com/ridafkih/keeper.sh/commit/aea1cf537b850509e802b388f38cf1482cb6291b","https://www.vulncheck.com/advisories/keeper-sh-calendar-version-prior-to-ssrf-guard-bypass-via-dns-rebinding"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/75xxx/CVE-2026-75583.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-75583","state":"PUBLISHED","datePublished":"2026-08-19T16:35:53.999Z","dateUpdated":"2026-08-21T11:21:04.300Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-17T22:02:43.612Z"},"containers":{"cna":{"title":"keeper.sh Calendar version prior to 2.18.14 SSRF Guard Bypass via DNS Rebinding","descriptions":[{"lang":"en","value":"keeper.sh's calendar module version prior to 2.18.14 contains a server-side request forgery (SSRF) guard bypass vulnerability that allows authenticated attackers to reach private network addresses by exploiting a DNS rebinding attack against the two-phase URL validation and connection flow.
