{"id":"CVE-2026-53574","summary":"EspoCRM: Blind SQL injection via streamAttachments where-clause complex expression","details":"EspoCRM is an open source customer relationship management application. From 8.1.0 until 9.3.8, an authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint because that query path permits complex expressions. Boolean-based blind SQL injection can extract arbitrary database information, including active administrator session tokens, and can enable full privilege escalation. This issue is fixed in version 9.3.8.","aliases":["GHSA-qgm7-fc9g-fj75"],"modified":"2026-10-16T02:47:47.836599612Z","published":"2026-10-15T14:45:52.943Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53574.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-89"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53574.json"},{"type":"FIX","url":"https://github.com/espocrm/espocrm/commit/e4a6aea90886d672f96b5d9a7cb0722e3d3654e1"},{"type":"WEB","url":"https://github.com/espocrm/espocrm/releases/tag/9.3.8"},{"type":"ADVISORY","url":"https://github.com/espocrm/espocrm/security/advisories/GHSA-qgm7-fc9g-fj75"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53574"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/espocrm/espocrm","events":[{"introduced":"2d629eb0c6082e5a63653bba336fe1e34ffbabac"},{"fixed":"1cba2949cd51ba54e72b7e86cd6eacca69ebc3fc"}],"database_specific":{"extracted_events":[{"introduced":"8.1.0"},{"fixed":"9.3.8"}],"source":"AFFECTED_FIELD"}}],"versions":["9.3.7","9.3.6","9.3.5","9.3.4","9.3.3","9.3.2","9.3.1","9.3.0","9.2.0","9.1.0","9.0.2","9.0.1","9.0.0","8.4.0","8.2.0","8.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53574.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L"}]}
