Axios Prototype Pollution Vulnerability: Early Warning
Axios versions >=1.15.2 and <1.18.0 reportedly contain prototype-pollution read-side gadgets in Basic auth subfield handling, potentially allowing an attacker to inject Basic auth credentials.
What happened
Axios versions >=1.15.2 and <1.18.0 are under investigation for a potential vulnerability involving prototype pollution in the handling of Basic auth subfields. This issue appears to allow an attacker, who controls the polluted prototype values, to inject attacker-chosen Basic auth credentials or replace an existing Authorization header. To assess your exposure, check if your project dependencies include Axios within the affected version range. It is recommended to upgrade to axios@1.18.0 or later to mitigate this risk. For more details, consult the primary sources.
