From version 5.7.0 until 5.7.12, TableAccessVoter::hasAccessToModule() in core-bundle/src/Security/Voter/DataContainer/TableAccessVoter.php caches authorization decisions using only $tokenHash, a hash of the user's security token, and omits the table returned by getDataSource(). If one request first checks a table allowed to the user and then a different denied table, the voter can reuse the allowed result, while DefaultDataContainerVoter can convert an incorrect abstention into a grant. A low-privileged backend user can consequently read, create, update, or delete records in tables outside assigned module permissions, including tables containing member or newsletter-subscriber data. This issue is fixed in version 5.7.12.","state":0,"publishedAt":"2026-10-09T20:26:31.329+00:00","modifiedAt":"2026-10-13T17:03:02.847+00:00","affected":[{"ecosystem":"Vendor product","name":"contao","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"contao\",\n                    \"product\": \"contao\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 5.7.0, < 5.7.12\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/contao/contao/security/advisories/GHSA-5974-gfqc-wrcm","https://github.com/contao/contao/commit/9d6f582a4cc6a758ce11d1043fc9c0ba62c5f4c9","https://github.com/contao/contao/releases/tag/5.7.12"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107851","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107851","identifiers":["CVE-2026-107851"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
