In BigBlueButton starting with 2.2 but before 2.3.18 and 2.4-rc-1, an attacker can circumvent access controls to gain access to all breakout rooms of the meeting they are in.

There are currently no known workarounds. | |||||
| CVE-2022-29232 | 1 Bigbluebutton | 1 Bigbluebutton | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| BigBlueButton is an open source web conferencing system.

| CVE-2022-29169 | 1 Bigbluebutton | 1 Bigbluebutton | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| BigBlueButton is an open source web conferencing system. Versions starting with 2.2 and prior to 2.3.19, 2.4.7, and 2.5.0-beta.2 are vulnerable to regular expression denial of service (ReDoS) attacks. By using specific a RegularExpression, an attacker can cause denial of service for the bbb-html5 service. The useragent library performs checking of device by parsing the input of User-Agent header and lets it go through lookupUserAgent() (alias of useragent.lookup() ). This function handles input by regexing and attackers can abuse that by providing some ReDos payload using `SmartWatch`. The maintainers removed `htmlclient/useragent` from versions 2.3.19, 2.4.7, and 2.5.0-beta.2. As a workaround, disable NginX forwarding the requests to the handler according to the directions in the GitHub Security Advisory. | |||||
| CVE-2022-27238 | 1 Bigbluebutton | 1 Bigbluebutton | 2024-11-21 | 3.5 LOW | 5.4 MEDIUM |
| BigBlueButton version 2.4.7 (or earlier) is vulnerable to stored Cross-Site Scripting (XSS) in the private chat functionality. A threat actor could inject JavaScript payload in his/her username.

| CVE-2022-23490 | 1 Bigbluebutton | 1 Bigbluebutton | 2024-11-21 | N/A | 4.3 MEDIUM |
| BigBlueButton is an open source web conferencing system. Versions prior to 2.4.0 expose sensitive information to Unauthorized Actors. This issue affects meetings with polls, where the attacker is a meeting participant. Subscribing to the current-poll collection does not update the client UI, but does give the attacker access to the contents of the collection, which include the individual poll responses. This issue is patched in version 2.4.0. There are no workarounds. | |||||
| CVE-2022-23488 | 1 Bigbluebutton | 1 Bigbluebutton | 2024-11-21 | N/A | 6.5 MEDIUM |
| BigBlueButton is an open source web conferencing system. Versions prior to 2.4-rc-6 are vulnerable to Insertion of Sensitive Information Into Sent Data. The moderators-only webcams lock setting is not enforced on the backend, which allows an attacker to subscribe to viewers' webcams, even when the lock setting is applied. (The required streamId was being sent to all users even with lock setting applied). This issue is fixed in version 2.4-rc-6. There are no workarounds. | |||||
