CVE-2023-33187

Date: May 26, 2023

Highlight is an open source, full-stack monitoring platform. Highlight may record passwords on customer deployments when a password html input is switched to "type="text"" via a javascript "Show Password" button. This differs from the expected behavior which always obfuscates "type="password"" inputs. A customer may assume that switching to "type="text"" would also not record this input; hence, they would not add additional "highlight-mask" css-class obfuscation to this part of the DOM, resulting in unintentional recording of a password value when a "Show Password" button is used. This issue was patched in version 6.0.0. This patch tracks changes to the "type" attribute of an input to ensure an input that used to be a "type="password"" continues to be obfuscated.
