Description Ganesh 2026-08-27 10:06:35 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

When using the "configparser" module to write configuration files
containing multi-line text values with carriage return characters (\r) the
resulting file could be injected with unexpected keys and values if the
attacker controls the written value.
Comment 1 Michel Lind 2026-10-06 13:15:24 UTC 
This CVE is in the language interpreter and is fixed by the interpreter's own update; this package only uses the affected module and needs no change of its own.
