{"id":"CVE-2026-75505","summary":"EspoCRM: Access control bypass in Mass Update letting regular user with Mass Update permission read any attachment","details":"EspoCRM is an open source customer relationship management application. Prior to 10.0.2, an authenticated user with mass-update permission can supply a known attachment identifier to the mass-update functionality. The mass-update processor duplicates the attachment without checking whether the caller can read it, bypassing record-level and field-level restrictions and exposing the file contents through the copied attachment. Obtaining a valid attachment identifier may be difficult. This issue is fixed in version 10.0.2.","aliases":["GHSA-24pg-2q7q-m5p6"],"modified":"2026-10-16T02:48:06.627217561Z","published":"2026-10-15T15:04:02.253Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75505.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75505.json"},{"type":"FIX","url":"https://github.com/espocrm/espocrm/commit/5be3e7ef2a010c151551a8bc277e9ca61e1503d4"},{"type":"WEB","url":"https://github.com/espocrm/espocrm/releases/tag/10.0.2"},{"type":"ADVISORY","url":"https://github.com/espocrm/espocrm/security/advisories/GHSA-24pg-2q7q-m5p6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75505"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/espocrm/espocrm","events":[{"introduced":"0"},{"fixed":"f6f561e3dacb6329891a83899fe07a75cbe0b9c8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"10.0.2"}],"source":"AFFECTED_FIELD"}}],"versions":["10.0.1","10.0.0","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","8.0.2","8.0.1","8.0.0","7.4.3","7.4.2","7.4.1","7.4.0","7.3.0","7.2.0","7.1.3","7.1.2","7.1.1","7.1.0","7.0.8","7.0.7","7.0.6","7.0.5","7.0.4","7.0.3","7.0.2","7.0.1","7.0.0","6.0.1","6.0.0","6.0.0-beta4","6.0.0-beta2","6.0.0-beta1","5.9.2","5.9.1","5.9.0","5.8.2","5.8.1","5.8.0","5.7.5","5.7.4","5.7.3","5.7.2","5.7.1","5.7.0","5.6.1","5.6.0","5.5.1","5.5.0","5.4.3","5.4.2","5.4.1","5.4.0","5.3.2","5.3.1","5.3.0","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2.0","5.1.2","5.1.1","5.1.0","5.0.1","5.0.0","4.8.0","4.7.0","4.6.0","4.5.0","4.4.0","4.3.0","4.3.0-beta.2","4.3.0-beta.1","4.2.4","4.2.3","4.2.2","4.2.1","4.2.0","4.1.4","4.1.3","4.1.2","4.1.1","4.1.0","4.0.3","4.0.2","4.0.1","4.0.0","4.0.0-beta.4","4.0.0-beta.3","4.0.0-beta.2","4.0.0-beta.1","3.9.1","3.9.0","3.8.0","3.7.1","3.7.0","3.6.1","3.6.0","3.5.0","3.4.2","3.4.1","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0","2.9.0","2.8.1","2.8.0","2.6.0","2.5.2","2.5.1","2.5.0","2.4.0","2.3.0","2.0.1","1.2.0","1.1.2","1.1.1","1.1.0","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-75505.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
