{"id":"CVE-2026-54569","state":"PUBLISHED","title":"SENAITE.CORE: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') and Missing Authorization in senaite.core","description":"SENAITE.CORE is the core framework for the SENAITE laboratory information management system. From 2.0.0 to 2.6.0, the SENAITE.CORE JSON API permits unauthenticated remote code execution through a two-request chain involving missing authorization and unsafe evaluation. The state-changing routes in src/bika/lims/jsonapi/update.py, including update, update_many, remove, doActionFor, doActionFor_many, and getusers, do not enforce the senaite.core: Access JSON API permission before resolving attacker-selected objects. In src/bika/lims/jsonapi/init.py, set_fields_from_request passes raw request values for RecordsField and RecordField instances to eval() before field mutator write-permission checks execute. An anonymous attacker can discover the bika_setup object identifier through @@uuid, send a value such as RejectionReasons to /@@API/update, and execute arbitrary Python in the Zope worker before a later mutation failure rolls back ZODB changes. The same unsafe evaluation pattern is present in src/senaite/core/browser/fields/record.py and src/senaite/core/browser/fields/records.py. Successful exploitation can expose or modify laboratory data, files, and accounts and can disrupt the service.","publishedAt":"2026-08-26T15:28:19.919Z","updatedAt":"2026-08-26T17:35:57.088Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["senaite senaite.core"],"affected":[{"vendor":"senaite","product":"senaite.core","versions":[{"version":">= 2.0.0, <= 2.6.0","status":"affected"}]}],"references":["https://github.com/senaite/senaite.core/security/advisories/GHSA-jrw6-7x4q-w25j","https://github.com/senaite/senaite.core/pull/2903","https://github.com/senaite/senaite.core/pull/2919","https://github.com/senaite/senaite.core/commit/a24d65e99a17ac43c5374ed9f0a60d0fe60d2f74","https://github.com/senaite/senaite.core/commit/ef4b6d73575b0fbc0edc6114e5e025089aaf9eb7"],"weaknesses":["CWE-95","CWE-862"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54569.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54569","state":"PUBLISHED","datePublished":"2026-08-26T15:28:19.919Z","dateUpdated":"2026-08-26T17:35:57.088Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T19:15:27.343Z"},"containers":{"cna":{"title":"SENAITE.CORE: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') and Missing Authorization in senaite.core","descriptions":[{"lang":"en","value":"SENAITE.CORE is the core framework for the SENAITE laboratory information management system.
