GHSA-x49m-3cw7-gq5q: jcvi (CVE-2023-35932)

Package	Ecosystem	Affected	Fixed in
jcvi	PyPI	<=1.3.5	No fixed version yet

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-x49m-3cw7-gq5q concerns jcvi versions up to and including 1.3.5. User input that is not sanitized can reach the jcvi configuration file at ~/.jcvirc, allowing an attacker to inject arbitrary configuration keys and values. The source says this could lead to command injection if configuration values are later executed as shell code, but it gives few details on the conditions required. No fixed version is listed.
