{"id":"CVE-2026-40584","summary":"RansomLook - Improper Filtering of Private Location Entries in API Endpoints Leads to Information Exposure","details":"RansomLook is a tool to monitor Ransomware groups and markets and extract their victims. Prior to 1.9.0, the API in the affected application improperly filters private location entries in website/web/api/genericapi.py. Because the code removes elements from a list while iterating over it, entries marked as private may be unintentionally retained in API responses, allowing unauthorized disclosure of non-public location information. This vulnerability is fixed in 1.9.0.","aliases":["GHSA-hv66-vcqc-v87c"],"modified":"2026-08-12T03:51:16.144570717Z","published":"2026-04-21T17:05:25.349Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40584.json"},"references":[{"type":"WEB","url":"https://vulnerability.circl.lu/vuln/gcve-1-2026-0025"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40584.json"},{"type":"ADVISORY","url":"https://github.com/RansomLook/RansomLook/security/advisories/GHSA-hv66-vcqc-v87c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40584"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ransomlook/ransomlook","events":[{"introduced":"0"},{"fixed":"f500bd0a0f93628c3d4ea2babd92d3e46139fc72"}],"database_specific":{"cpe":"cpe:2.3:a:ransomlook:ransomlook:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.9.0"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["1.8.0","1.6.0","1.5.0","1.4.0","1.3.0","1.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40584.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:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
