Description

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.

  • Affected version(s): <= 2.0.0
  • Patched version(s): 2.0.1
