A brand new relay called "api" has been devleopped since 6 months : it's an HTTP REST API, which should in long term replace completey the "weechat" protocol.

The "api" relay provides the following key features:

• easy client implementation: HTTP REST API, JSON input/output, use of ANSI color codes
• automatic compression of responses (deflate, gzip, zstd and permessage-deflate for websocket)
• data synchronization: real-time sync with websocket or polling with HTTP requests
• no internal structures exposed: no use of pointers & complex structures like hdata
• WeeChat itself can connect to another WeeChat using this protocol (also known as relay "remote")

Documentation: Relay API.

The new /remote command lets you connect to the "api" relay of another running WeeChat (it must expose the same API version).

To connect to a remote WeeChat, just add a relay on the remote (for TLS, which is recommended, replace api by tls.api):

/set relay.network.password "secr3t"
/relay add api 9000

On the client, supposing it's running on the same machine:

/remote add test http://localhost:9000 -password=secr3t
/remote connect test

Then all buffers of remote WeeChat are opened locally by relay and any text or command sent on these buffers are sent and executed on the remote WeeChat.

Input is also synchronized (from remote to local WeeChat only), so that remote buffers like /fset can be used locally, including keys like Alt+Enter to set input with a command to execute.
Only the local buffer mouse actions are not yet supported (ie you can not scroll the fset buffer with mouse).

Version 4.2.1 is available, see bugs fixed in the ChangeLog v4.2.1.

Versions 4.0.8 and 4.1.3 are available, see bugs fixed in the ChangeLog v4.0.8 and ChangeLog v4.1.3.

Version 4.0.5 is available, see new features and bugs fixed in the ChangeLog.

Version 4.0.3 is available, it fixes the following bugs:

• fix input length and crash after delete of line
• fix display of self IRC CTCP message containing bold attribute
• fix memory leak in IRC message parser
• fix switch to IRC channel manually joined when server option autojoin_dynamic is on and option irc.look.buffer_switch_autojoin is off
• fix display of outgoing IRC notice with channel when capability "echo-message" is enabled
• fix display of IRC CTCP messages received from relay client
• display a warning in build of docs if a locale is missing with fallback to English for auto-generated content

Version 4.0.1 is available, it fixes the following bugs:

• display actual key name and command with Alt+k, remove key Alt+K (grab raw key) and associated commands /input grab_raw_key and /input grab_raw_key_command
• check for newline characters in string_is_whitespace_char
• do not convert option name to lower case in API functions config_set_plugin and config_set_desc_plugin
• fix crash on quit with Guile < 3
• reply to a IRC CTCP request sent to self nick

One thing is sure, we're not kidding with the security vulnerabilities, and our goal is to be completely transparent with the users about the issues as soon as they are public (ie with a new version, a fix/patch or at least a workaround available).

In this context, the security page has been redesigned from scratch, it is more user-friendly and a lot of new information has been added about each vulnerability.

The URL is unchanged: https://weechat.org/doc/security/.

Among the new information:

• A "WSA" identifier (WeeChat Security Advisory), which is unique by vulnerability, and built like this: WSA-YEAR-ID (YEAR on 4 digits, and the ID starts to 1 for the first vulnerability of this year, 2 for the second, etc.).
• The CVSS vector, score and severity, for more information:
  • FIRST - CVSS v3.1 specification: https://www.first.org/cvss/specification-document
  • NVD - CVSS v3 calculator: https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator
• The vulnerability type, also known as CWE (Common Weakness Enumeration), for more information: https://cwe.mitre.org/
• The short description of the issue.
• The scope: which part of WeeChat is affected: it can be one or multiple plugins or features.
• More detailed information about the mitigation for the issue.
• The credit: who found the issue and reported it to WeeChat security team (displayed only with the agreement of the reporter).

Important: due to the way the CVSS vector, score and severity are computed, the severity level previously displayed has changed for some vulnerabilities and is now higher:

• WSA-2021-1 (Crash on malformed websocket frame in relay plugin): medium -> high (score: 7.5)
• WSA-2020-3 (Buffer overflow on new IRC message 005 with nick prefixes): low -> high (score: 7.5)
• WSA-2020-2 (Crash on malformed IRC message 352 (WHO)): low -> high (score: 7.5)
• WSA-2020-1 (Buffer overflow on malformed IRC message 324 (channel mode)): low -> high (score: 7.5)
• WSA-2013-3 (Crash on IRC commands sent via Relay): medium -> high (score: 7.5)
• WSA-2013-2 (Crash on send of unknown commands to IRC server): low -> medium (score: 5.5)
• WSA-2013-1 (Crash on nicks monitored with /notify): low -> medium (score: 5.5)
• WSA-2006-1 (Crash in API function infobar_printf): low -> medium (score: 6.2)
• WSA-2004-1 (Buffer overflows in build of strings): low -> medium (score: 6.2)

The page is now separated into two parts: the overview with only part of the info, and detail of each vulnerability below.

The overview shows synthesized data (click for full size):

Below this, the detail of each vulnerability is displayed, for example this detail about the latest security vulnerability, fixed in version 3.2.1 (September 2021):

For convenience, a list of vulnerabilities by WeeChat version is also available:

For the record and reference (especially old severities), the previous security page was:

Version 3.4 is available!

As usual, many new features and bug fixes, see ChangeLog for detail.

A brand new dark theme has been added on WeeChat.org!

The use of this dark theme is automatic (following your desktop/browser configuration).
It can be forced by a new link displayed at the bottom of any page: "Theme: auto (dark, light)".

New dark theme (click for full size):

The light theme:

Hope you like this new eye-friendly dark theme!

Version 3.2.1 is available, it fixes a security vulnerability: a malformed websocket frame received in relay plugin can cause a crash (CVE-2021-40516).

Upgrade is recommended for all users.

IRC SASL SCRAM authentication has been added in WeeChat 3.2, with 3 new mechanisms:

• scram-sha-1: SASL SCRAM with SHA-1 digest algorithm,
• scram-sha-256: SASL SCRAM with SHA-256 digest algorithm,
• scram-sha-512: SASL SCRAM with SHA-512 digest algorithm.

References:

• Support of SASL mechanisms in IRC clients: https://ircv3.net/docs/sasl-mechs
• RFC 7677 (SCRAM-SHA-256 and SCRAM-SHA-256-PLUS): https://datatracker.ietf.org/doc/ht...

Due to the recent events affecting freenode (see references below), the WeeChat official and unofficial channels have moved from freenode to libera.chat:

• official channels: #weechat, #weechat-fr
• non-official channels: #weechat-de, #weechat-fi
• off-topic channel: #weechat-offtopic

To add a new libera server and connect to it, joining only the English support channel:

/server add libera irc.libera.chat/6697 -ssl -autojoin=#weechat
/connect libera

To join the French channel as well:

/server add libera irc.libera.chat/6697 -ssl -autojoin=#weechat,#weechat-fr
/connect libera

If all your freenode channels have moved to libera, you can also rename the server and change the address:

/disconnect freenode
/server rename freenode libera
/set irc.server.libera.addresses "irc.libera.chat/6697"
/set irc.server.libera.ssl on
/connect libera

See you soon on libera!
