{"id":"CVE-2026-75856","summary":"CodeWhale before 0.8.64 SSRF Bypass via DNS Pinning TOCTOU","details":"CodeWhale before 0.8.64 contains a server-side request forgery bypass vulnerability in DNS pinning logic that fails to prevent time-of-check-time-of-use attacks. Attackers can manipulate DNS responses to fail initial resolution checks and succeed on secondary requests, allowing requests to internal IP addresses and bypassing SSRF mitigations.","aliases":["GHSA-6v2g-fpxh-pmmh"],"modified":"2026-09-10T03:30:59.702688365Z","published":"2026-08-18T15:21:55.627Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75856.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75856.json"},{"type":"ADVISORY","url":"https://github.com/Hmbown/CodeWhale/security/advisories/GHSA-6v2g-fpxh-pmmh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75856"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/codewhale-before-ssrf-bypass-via-dns-pinning-toctou"},{"type":"FIX","url":"https://github.com/Hmbown/CodeWhale/commit/26de44a8bd5051f8f944ea60b2c37ae1d2b7d25e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hmbown/codewhale","events":[{"introduced":"2d61513a9ea762fd2ffb3565e0dd819a400e8532"},{"fixed":"5fa24733e9a1d11315506309b8edb0fdf2b94f04"},{"introduced":"5fa24733e9a1d11315506309b8edb0fdf2b94f04"},{"fixed":"9d2e6a89f58610d5f426ff26533a2bf312023790"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.8.5"},{"fixed":"0.8.41"},{"introduced":"0.8.41"},{"fixed":"0.8.64"}]}}],"versions":["v0.8.60","v0.8.40","v0.8.63","v0.8.62","v0.8.61","v0.8.59","v0.8.58","v0.8.57","v0.8.56","v0.8.55","v0.8.53","v0.8.54","v0.8.52","v0.8.51","v0.8.50","v0.8.49","v0.8.48","v0.8.46","v0.8.45","v0.8.44","v0.8.43","v0.8.42","v0.8.41","v0.8.39","v0.8.38","v0.8.37","v0.8.36","v0.8.35","v0.8.33","v0.8.32","v0.8.31","v0.8.30","v0.8.28","v0.8.29","v0.8.27","v0.8.26","v0.8.25","v0.8.24","v0.8.23","v0.8.22","v0.8.21","v0.8.20","v0.8.19","v0.8.18","v0.8.17","v0.8.15","v0.8.14","v0.8.13","v0.8.12","v0.8.11","v0.8.10","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-75856.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:H/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
