The rimons-twitter-widget plugin before 1.3 for WordPress has XSS.

This vulnerability was caused by an incomplete fix to CVE-2017-0911. Twitter Kit for iOS versions 3.0 to 3.4.0 is vulnerable to a callback verification flaw in the "Login with Twitter" component allowing an attacker to provide alternate credentials. In the final step of "Login with Twitter" authentication information is passed back to the application using the registered custom URL scheme (typically twitterkit-<consumer-key>) on iOS. Because the callback handler did not verify the authenticity of the response, this step is vulnerable to forgery, potentially allowing attacker to associate a Twitter account with a third-party service.

Twitter Kit for iOS versions 3.0 to 3.2.1 is vulnerable to a callback verification flaw in the "Login with Twitter" component allowing an attacker to provide alternate credentials. In the final step of "Login with Twitter" authentication information is passed back to the application using the registered custom URL scheme (typically twitterkit-<consumer-key>) on iOS. Because the callback handler did not verify the authenticity of the response, this step is vulnerable to forgery, potentially allowing attacker to associate a Twitter account with a third-party service.

The Twitter iOS client versions 6.62 and 6.62.1 fail to validate Twitter's server certificates for the /1.1/help/settings.json configuration endpoint, permitting man-in-the-middle attackers the ability to view an application-only OAuth client token and potentially enable unreleased Twitter iOS app features.

The Twitter module 6.x-5.x before 6.x-5.2, 7.x-5.x before 7.x-5.9, and 7.x-6.x before 7.x-6.0 for Drupal does not properly check access permissions, which allows remote authenticated users to post tweets to arbitrary accounts by leveraging the (1) "post to twitter" permission or change the options for arbitrary attached accounts by leveraging the (2) "add twitter accounts" or (3) "add authenticated twitter accounts" permission.

Cross-site request forgery (CSRF) vulnerability in the Twitter LiveBlog plugin 1.1.2 and earlier for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the mashtlb_twitter_username parameter in the twitter-liveblog.php page to wp-admin/options-general.php.

Multiple cross-site request forgery (CSRF) vulnerabilities in the Post to Twitter plugin 0.7 and earlier for WordPress allow remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the (1) idptt_twitter_username or (2) idptt_tweet_prefix parameter to wp-admin/options-general.php.

Cross-site request forgery (CSRF) vulnerability in the twitterDash plugin 2.1 and earlier for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the username_twitterDash parameter in the twitterDash.php page to wp-admin/options-general.php.

Multiple cross-site request forgery (CSRF) vulnerabilities in the iTwitter plugin 0.04 and earlier for WordPress allow remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the (1) itex_t_twitter_username or (2) itex_t_twitter_userpass parameter in the iTwitter.php page to wp-admin/options-general.php.

The Groupama toujours la (aka com.groupama.toujoursla) application 1.3.0 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
