{"id":"CVE-2026-44718","summary":"Mathesar: Missing collaborator checks allowed access to saved explorations in other databases","details":"Mathesar is a web application that makes working with PostgreSQL databases both simple and powerful. From 0.2.0 to before 0.10.0, explorations.get, explorations.replace, and explorations.delete operate on an exploration_id without verifying that the requesting user was a collaborator on the exploration’s database. An authenticated user on the same Mathesar installation who knew or guessed an exploration ID could read, replace, or delete a saved exploration belonging to a database where they were not a collaborator. This affected Mathesar-managed saved exploration definitions, including names, descriptions, selected columns, display metadata, filters, sorting, and transformations. This vulnerability is fixed in 0.10.0.","aliases":["GHSA-wf8r-g5rp-w69f"],"modified":"2026-08-04T11:49:52.722807917Z","published":"2026-05-15T18:23:10.517Z","database_specific":{"cwe_ids":["CWE-639","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44718.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44718.json"},{"type":"ADVISORY","url":"https://github.com/mathesar-foundation/mathesar/security/advisories/GHSA-wf8r-g5rp-w69f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44718"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mathesar-foundation/mathesar","events":[{"introduced":"a5328e98341616fca0cf58fa3a62649a653f344d"},{"fixed":"ec0600b32fd10ae9578bf7190c123559f041b944"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.2.0"},{"fixed":"0.10.0"}]}}],"versions":["0.9.0","0.8.0","0.7.1","0.7.0","0.6.0","0.4.0","0.2.5","0.2.4","0.2.3","0.2.2","0.2.1","0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44718.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
