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.
CVE-2023-33187
This medium-severity CVE scores 5.4 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 79% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
