consumerweb-captcha is a malicious package. This package contains malicious code, and its content was removed from the official package manager. While this package might be attempting to impersonate a valid organization, there is no connection between that organization and this package authorship.

urllib3 is a HTTP library with thread-safe connection pooling, file post, and more.

Affected versions of this package are vulnerable to Open Redirect due to the retries parameter being ignored during PoolManager instantiation. An attacker can access unintended resources or endpoints by leveraging automatic redirects when the application expects redirects to be disabled at the connection pool level.

Note:

requests and botocore users are not affected.

io.jenkins.plugins:dingding-notifications is a Dingtalk for jenkins.

Affected versions of this package are vulnerable to Improper Input Validation due to the unconditional disabling of SSL/TLS certificate and hostname validation for connections. An attacker can intercept and manipulate secure communications by exploiting this lack of validation.
