GHSA-cxqv-r2cc-r9c9

Improper input validation of octal strings in Python stdlib ipaddress 3.10 and below allows unauthenticated remote attackers to perform indeterminate SSRF, RFI, and LFI attacks on many programs that rely on Python stdlib ipaddress. IP address octects are left stripped instead of evaluated as valid IP addresses.
