Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
aiograpi versions before 0.9.10 accepted server-supplied signup challenge paths and used them to build request URLs without first checking that they were relative Instagram API paths. An attacker who can supply a malicious or tampered challenge payload could cause requests to be sent outside the intended Instagram host, carrying the client's existing session headers. Upgrade to aiograpi 0.9.10, which validates challenge paths before building URLs or submitting challenge forms.
