CVE-2026-24471 2 Conduit, Continuwuity 2 Conduit, Continuwuity 2026-02-04 N/A
continuwuity is a Matrix homeserver written in Rust. This vulnerability allows an attacker with a malicious remote server to cause the local server to sign an arbitrary event upon user interaction. Upon a user account leaving a room (rejecting an invite), joining a room or knocking on a room, the victim server may ask a remote server for assistance. If the victim asks the attacker server for assistance the attacker is able to provide an arbitrary event, which the victim will sign and return to the attacker. For the /leave endpoint, this works for any event with a supported room version, where the origin and origin_server_ts is set by the victim. For the /join endpoint, an additionally victim-set content field in the format of a join membership is needed. For the /knock endpoint, an additional victim-set content field in the format of a knock membership and a room version not between 1 and 6 is needed. This was exploited as a part of a larger chain against the continuwuity.org homeserver. This vulnerability affects all Conduit-derived servers. This vulnerability is fixed in Continuwuity 0.5.1, Conduit 0.10.11, Grapevine 0aae932b, and Tuwunel 1.4.9.
CVE-2024-6303 1 Conduit 1 Conduit 2024-11-21 9.9 Critical
Missing authorization in Client-Server API in Conduit <=0.7.0, allowing for any alias to be removed and added to another room, which can be used for privilege escalation by moving the #admins alias to a room which they control, allowing them to run commands resetting passwords, siging json with the server's key, deactivating users, and more
CVE-2024-6302 1 Conduit 1 Conduit 2024-11-21 8.1 High
Lack of privilege checking when processing a redaction in Conduit versions v0.6.0 and lower, allowing a local user to redact any message from users on the same server, given that they are able to send redaction events.
CVE-2024-6301 1 Conduit 1 Conduit 2024-11-21 5.3 Medium
Lack of validation of origin in federation API in Conduit, allowing any remote server to impersonate any user from any server in most EDUs
CVE-2024-6300 1 Conduit 1 Conduit 2024-11-21 3.7 Low
Incomplete cleanup when performing redactions in Conduit, allowing an attacker to check whether certain strings were present in the PDU before redaction
CVE-2024-6299 1 Conduit 1 Conduit 2024-11-21 4.8 Medium
Lack of consideration of key expiry when validating signatures in Conduit, allowing an attacker which has compromised an expired key to forge requests as the remote server, as well as PDUs with timestamps past the expiry date
