{"id":"CVE-2026-43934","summary":"e107: Broken Access Control in e107 comment edit allows cross-user comment modification","details":"e107 is a content management system (CMS). Prior to 2.3.4, a Broken Access Control vulnerability exists in the application, allowing an unauthorized authenticated user to edit comments posted by others. This stems from inadequate server-side access control validation, where the application depends only on a predictable identifier in the request to determine which comment to edit, without confirming the requesting user’s ownership of the comment. This vulnerability is fixed in 2.3.4.","aliases":["GHSA-5w63-63rh-99q6"],"modified":"2026-07-08T08:02:18.593584998Z","published":"2026-05-26T14:54:21.210Z","database_specific":{"cwe_ids":["CWE-284","CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43934.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43934.json"},{"type":"ADVISORY","url":"https://github.com/e107inc/e107/security/advisories/GHSA-5w63-63rh-99q6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43934"},{"type":"FIX","url":"https://github.com/e107inc/e107/commit/23961a8f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/e107inc/e107","events":[{"introduced":"0"},{"fixed":"23961a8f"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.3.4"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43934.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
