CVE-2022-46146: Prometheus Exporter Toolkit

High severity, CVSS 8.8. EPSS: 1.3% chance of exploitation in the next 30 days.

Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There is no workaround, but attacker must have access to the hashed password to use this functionality.

Affected products

• Prometheus Exporter Toolkit: before 0.7.2 (fixed in 0.7.2); from 0.8.0, before 0.8.2 (fixed in 0.8.2)
