Starting in version 5.0.0-beta1 and prior to versions 5.3.2 and 5.4.2, `PermissionGroupsService::build()` reads a plugin's `config/permission.php` to decide what each user group may reach. When that file is absent it writes a wildcard allow rule instead: `url` `/baser/<prefix>/<plugin>/*`, `method` `*`, `auth` true, for every non-admin group. BcCustomContent has no such file in any release. After an administrator installs it, the default `operators` group can store and execute arbitrary PHP under the document root. Versions 5.3.2 and 5.4.2 patch the issue.","state":0,"publishedAt":"2026-10-23T13:34:26.038+00:00","modifiedAt":"2026-10-23T14:58:03.802+00:00","affected":[{"ecosystem":"Vendor product","name":"basercms","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"baserproject\",\n                    \"product\": \"basercms\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 5.0.0-beta1, < 5.3.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 5.4.0, < 5.4.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5,"severity":"HIGH"}],"references":["https://github.com/baserproject/basercms/security/advisories/GHSA-8jrp-4h7c-m679","https://github.com/baserproject/basercms/commit/2ed19c878add5c26fc765572e0e77173c1f1fdb5","https://github.com/baserproject/basercms/commit/b0ef31b10dc6267b48ebc9a80d34bc7c4c09c311","https://github.com/baserproject/basercms/releases/tag/5.3.2","https://github.com/baserproject/basercms/releases/tag/5.4.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115481","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115481","identifiers":["CVE-2026-115481"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
