Server-Side Request Forgery (SSRF)

Axios is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to improper hostname normalization when evaluating NOPROXY rules, where crafted loopback addresses e.g., localhost. or ::1 bypass proxy exclusions and are routed through the proxy, allowing attackers to access...

cpython: cpython: `tarfile` module misinterprets crafted tar archives leading to data integrity issues

A flaw was found in the tarfile module of cpython. This vulnerability allows a remote attacker to craft a malicious tar archive that, when processed, could be misinterpreted by the tarfile module. This misinterpretation occurs because the module incorrectly applies normalization of AREGTYPE block...
