Description

Impact

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.

Patches

highlight.run@6.0.0 resolves the issue via https://github.com/rrweb-io/rrweb/pull/1184 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.

Workarounds

We have deployed a change to our data ingest to obfuscate passwords server side from older clients. This means that upgrading to the latest version of highlight.run is not necessary but recommended to prevent potential network transfer of recorded password data to our backend.
