Summary

XChat 1.8.7 and earlier, including default configurations of 1.4.2 and 1.4.3, allows remote attackers to execute arbitrary IRC commands as other clients via encoded characters in a PRIVMSG command that calls CTCP PING, which expands the characters in the client response when the percascii variable is set.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
