CVE-2024-52505 1 Matrix-org 1 Matrix-appservice-irc 2025-07-12 5.4 Medium
matrix-appservice-irc is a Node.js IRC bridge for the Matrix messaging protocol. The provisioning API of the matrix-appservice-irc bridge up to version 3.0.2 contains a vulnerability which can lead to arbitrary IRC command execution as the bridge IRC bot. The vulnerability has been patched in matrix-appservice-irc version 3.0.3.
CVE-2024-39691 1 Matrix-org 1 Matrix-appservice-irc 2024-11-21 4.3 Medium
matrix-appservice-irc is a Node.js IRC bridge for the Matrix messaging protocol. The fix for GHSA-wm4w-7h2q-3pf7 / CVE-2024-32000 included in matrix-appservice-irc 2.0.0 relied on the Matrix homeserver-provided timestamp to determine whether a user has access to the event they're replying to when determining whether or not to include a truncated version of the original event in the IRC message. Since this value is controlled by external entities, a malicious Matrix homeserver joined to a room in which a matrix-appservice-irc bridge instance (before version 2.0.1) is present can fabricate the timestamp with the intent of tricking the bridge into leaking room messages the homeserver should not have access to. matrix-appservice-irc 2.0.1 drops the reliance on `origin_server_ts` when determining whether or not an event should be visible to a user, instead tracking the event timestamps internally. As a workaround, it's possible to limit the amount of information leaked by setting a reply template that doesn't contain the original message.
CVE-2024-32000 1 Matrix-org 1 Matrix-appservice-irc 2024-11-21 4.3 Medium
matrix-appservice-irc is a Node.js IRC bridge for the Matrix messaging protocol. matrix-appservice-irc before version 2.0.0 can be exploited to leak the truncated body of a message if a malicious user sends a Matrix reply to an event ID they don't have access to. As a precondition to the attack, the malicious user needs to know the event ID of the message they want to leak, as well as to be joined to both the Matrix room and the IRC channel it is bridged to. The message reply containing the leaked message content is visible to IRC channel members when this happens. matrix-appservice-irc 2.0.0 checks whether the user has permission to view an event before constructing a reply. Administrators should upgrade to this version. It's possible to limit the amount of information leaked by setting a reply template that doesn't contain the original message. See these lines `601-604` in the configuration file linked.
CVE-2023-38690 2 Matrix, Matrix-org 2 Matrix Irc Bridge, Matrix-appservice-irc 2024-11-21 5.8 Medium
matrix-appservice-irc is a Node.js IRC bridge for Matrix. Prior to version 1.0.1, it is possible to craft a command with newlines which would not be properly parsed. This would mean you could pass a string of commands as a channel name, which would then be run by the IRC bridge bot. Versions 1.0.1 and above are patched. There are no robust workarounds to the bug. One may disable dynamic channels in the config to disable the most common execution method but others may exist.
