Description Pedro Sampaio 2021-05-11 18:16:34 UTC 
Credentials Plugin 2.3.18 and earlier does not escape user-controlled information on a view it provides. This results in a reflected cross-site scripting (XSS) vulnerability. Credentials Plugin 2.3.19 restricts the user-controlled information it provides to a safe subset.
