{"id":"CVE-2026-46688","state":"PUBLISHED","title":"Meeting Room Booking System has an unauthenticated open redirect","description":"The Meeting Room Booking System (MRBS) is a PHP-based application for booking meeting rooms. Prior to version 1.12.2, an unauthenticated request can be made to redirect the user to a query-specified location. This allows an attacker to create a specially-crafted URL to an MRBS installation that will cause the user who clicks it to be redirected to the attacker-specified redirect URL, which could be a spoofed MRBS login page, for example. Version 1.12.2 contains a fix. No known workarounds are available.","publishedAt":"2026-08-12T23:30:25.563Z","updatedAt":"2026-08-13T13:11:21.589Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["meeting-room-booking-system mrbs-code"],"affected":[{"vendor":"meeting-room-booking-system","product":"mrbs-code","versions":[{"version":"< 1.12.2","status":"affected"}]}],"references":["https://github.com/meeting-room-booking-system/mrbs-code/security/advisories/GHSA-6xcj-g522-859f","https://github.com/meeting-room-booking-system/mrbs-code/releases/tag/v1.12.2"],"weaknesses":["CWE-601"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/46xxx/CVE-2026-46688.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-46688","state":"PUBLISHED","datePublished":"2026-08-12T23:30:25.563Z","dateUpdated":"2026-08-13T13:11:21.589Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-15T21:46:51.548Z"},"containers":{"cna":{"title":"Meeting Room Booking System has an unauthenticated open redirect","descriptions":[{"lang":"en","value":"The Meeting Room Booking System (MRBS) is a PHP-based application for booking meeting rooms.
