In versions 5.0.0 before 5.3.2 and 5.4.0 before 5.4.2, the public POST /baser/api/bc-mail/mail_messages/add/{mailContentId}.json endpoint accepts submissions without enforcing the form's auth_captcha setting. BcMail\\Controller\\Api\\MailMessagesController::add() and MailMessagesService::create() omit the BcCaptchaService::check() verification of captcha_id and auth_captcha performed by MailController::submit() in the web UI. An unauthenticated attacker who can reach the API can therefore automate submissions without solving the enabled image challenge. The API disables FormProtection and has no rate limit; submissions can generate administrator-inbox spam, send attacker-influenced auto-replies to third parties when an email field is present, and accumulate mail_messages database records when save_info is enabled. The API already enforces the isAccepting() check added for CVE-2026-30878; the missing CAPTCHA check is a separate control failure. This issue has been patched in versions 5.3.2 and 5.4.2.","state":0,"publishedAt":"2026-10-23T13:37:32.184+00:00","modifiedAt":"2026-10-23T13:37:32.184+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, < 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 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/baserproject/basercms/security/advisories/GHSA-cpxq-6gjp-m59g","https://github.com/baserproject/basercms/commit/3444154ca40f308ade8991e54459248f866dcf61","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-2026-115480","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115480","identifiers":["CVE-2026-115480"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
