Echo: ruby-3.2: security update to 3.2.11+e3ruby-3.3: security update to 3.3.11+e3

medium Tenable Self-Hosted Container Security Plugin ID 463560

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to 0.6.5
 and 0.5.15, when Net::IMAP#id is called with a hash argument, although the ID field value strings are
 correctly quoted (escaping quoted specials), they were not validated to prohibit CRLF sequences. While
 Net::IMAP#enable does process its arguments for aliases, it does not validate them as valid atoms (or as a
 list of valid atoms). The #to_s value is sent verbatim. Arguments to either command could be used by an
 attacker to inject arbitrary IMAP commands. This vulnerability is fixed in 0.6.5 and 0.5.15.
 (CVE-2026-47242)

Solution

Update the ruby-3.2 library and its related packages to version 3.2.11+e3 or later.
