{"id":"CVE-2026-30833","summary":"Rocket.Chat: NoSQL injection in the EE ddp-streamer-service","details":"Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0, a NoSQL injection vulnerability exists in Rocket.Chat's account service used in the ddp-streamer micro service that allows unauthenticated attackers to manipulate MongoDB queries during authentication. The vulnerability is located in the username-based login flow where user-supplied input is directly embedded into a MongoDB query selector without validation. An attacker can inject MongoDB operator expressions (e.g., { $regex: '.*' }) in place of a username string, causing the database query to match unintended user records. This issue has been patched in versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0.","aliases":["GHSA-hgq6-9jg2-wf3f"],"modified":"2026-08-12T03:51:08.393904536Z","published":"2026-03-06T17:40:36.939Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-943"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30833.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30833.json"},{"type":"ADVISORY","url":"https://github.com/RocketChat/Rocket.Chat/security/advisories/GHSA-hgq6-9jg2-wf3f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30833"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rocketchat/rocket.chat","events":[{"introduced":"0"},{"fixed":"6b8946ad478975c3ef71efacf08566b52a2c1ca5"},{"introduced":"8d69961505afd986e64db5c7a332a65074a1ac4a"},{"fixed":"d32fd374936eb051f8d7d832caf011273233d609"},{"introduced":"05f9767358c446a93fabf21d8e77f884ac775c0a"},{"fixed":"110f5168f5d2e17ed83c182343de7a4965541ecd"},{"introduced":"98c9d579501d877c263fe0a1db3cb69d0b52bf92"},{"fixed":"54bc7edd110d77bdc81db8780980680c5fac43b4"},{"introduced":"9e2e148b8d8c474b307c24d59f8592a172f017f5"},{"fixed":"77478a8e54421abe38d1089f6153e6fa24a8f3ec"},{"introduced":"2ca98764a077deb7efb710ff1d8f78c5c3e4c4a3"},{"fixed":"6d98be177444392c7d751d51e3ffc57474474510"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"7.10.8"},{"introduced":"7.11.0"},{"fixed":"7.11.5"},{"introduced":"7.12.0"},{"fixed":"7.12.5"},{"introduced":"7.13.0"},{"fixed":"7.13.4"},{"introduced":"8.0.0"},{"fixed":"8.0.2"},{"introduced":"8.1.0"},{"fixed":"8.1.1"}]}}],"versions":["7.10.7","7.11.4","7.12.4","8.1.0","8.0.1","7.13.3","8.0.0","7.13.2","7.11.3","7.10.6","7.12.3","7.10.5","7.11.2","7.12.2","7.13.1","7.13.0","7.10.4","7.11.1","7.12.1","7.11.0","7.12.0","7.10.3","7.10.2","7.10.1","7.10.0","7.9.3","7.9.1","7.8.3","7.9.0","7.8.2","7.8.1","7.8.0","7.8.0-rc.1","7.8.0-rc.0","6.0.0","5.4.4","5.4.3","5.4.2","5.4.1","5.3.5","5.4.0","5.3.4","5.3.2","5.1.4","5.2.0","5.3.1","5.3.0","5.1.3","5.1.1","5.0.5","5.1.0","5.0.4","5.0.3","5.0.2","5.0.1","5.0.0","4.8.2","4.8.0","4.6.3","4.7.3","4.7.2","4.4.4","4.7.1","4.7.0","4.6.2","4.6.1","4.5.5","4.6.0","4.4.2","4.5.4","4.5.3","4.5.2","4.5.1","4.5.0","4.4.1","4.4.0","4.3.3","4.3.2","4.3.1","4.2.2","4.1.2","4.3.0","4.2.1","4.2.0","4.1.1","4.1.0","4.0.5","3.18.2","4.0.4","4.0.3","4.0.2","4.0.1","4.0.0","3.18.1","3.17.2","3.16.4","3.18.0","3.17.1","3.17.0","3.16.3","3.16.1","3.16.2","3.16.0","3.15.2","3.14.4","3.15.1","3.15.0","3.14.3","3.14.2","3.14.1","3.13.3","3.14.0","3.13.2","3.13.1","3.12.3","3.13.0","3.12.2","3.12.1","3.12.0","3.11.1","3.10.5","3.11.0","3.10.4","3.10.3","3.10.2","3.10.1","3.10.0","3.9.3","3.9.2","3.9.1","3.9.0","3.8.2","3.7.2","0.74.3","3.8.1","3.8.0","3.7.1","3.7.0","3.6.3","3.6.2","3.6.1","3.6.0","3.5.4","3.5.3","3.5.2","3.5.1","3.5.0","3.4.2","3.4.1","3.4.0","3.3.3","3.3.2","3.3.1","3.3.0","3.2.2","3.2.1","3.1.2","3.0.12","3.2.0","3.1.1","3.1.0","3.0.11","3.0.10","3.0.9","3.0.8","3.0.7","3.0.6","3.0.5","3.0.4","3.0.3","3.0.2","3.0.1","2.4.9","3.0.0","2.4.8","2.4.7","2.4.6","2.4.5","2.4.4","2.4.3","2.4.2","2.4.1","2.4.0","2.3.2","2.3.1","2.3.0","2.2.0","2.1.2","2.0.0","1.3.2","2.1.1","2.1.0","1.3.1","1.3.0","1.2.1","1.0.3","1.1.3","1.2.0","1.1.2","1.1.1","1.1.0","1.0.2","1.0.1","1.0.0","0.74.2","0.74.1","0.74.0","0.73.2","0.73.1","0.73.0","0.72.3","0.72.2","0.72.1","0.70.4","0.71.1","0.72.0","0.71.0","0.70.3","0.70.2","0.70.1","0.70.0","0.69.2","0.69.1","0.69.0","0.68.5","0.68.4","0.68.3","0.68.2","0.68.1","0.68.0","0.67.0","0.66.3","0.66.2","0.66.1","0.66.0","0.65.2","0.65.1","0.65.0","0.64.2","0.64.1","0.64.0","0.63.3","0.63.2","0.63.1","0.63.0","0.62.2","0.62.1","0.62.0","0.61.2","0.61.1","0.61.0","0.60.4","0.60.3","0.60.2","0.60.1","0.60.0","0.59.6","0.59.5","0.59.4","0.59.3","0.59.2","0.59.1","0.59.0","0.58.2","0.58.1","0.58.0","0.57.2","0.57.1","0.57.0","0.56.0","0.56.0-rc.7","0.56.0-rc.6","0.56.0-rc.5","0.56.0-rc.4","0.56.0-rc.3","0.56.0-rc.2","0.56.0-rc.1","0.56.0-rc.0","0.54.1","0.54.0","0.50.0","0.49.4","0.49.3","0.49.2","0.49.1","0.49.0","0.48.0","0.46.0","0.45.0","0.44.0","0.43.0","0.42.0","0.41.0","0.40.1","0.40.0","0.39.0","0.38.0","0.37.1","0.37.0","0.36.0","0.30.0","0.29.0","0.28.0","0.27.0","0.26.0","0.25.0","0.24.0","0.23.0","0.19.0","0.18.0","0.17.0","0.16.0","0.15.0","0.14.0","0.13.0","0.11.0","0.10.2","0.10.1","0.10.0","0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30833.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
