This critical-severity CVE scores 9.3 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 96% 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).

PCL (Plain Craft Launcher) Community Edition is a Minecraft launcher. In PCL CE versions 2.12.0-beta.5 to 2.12.0-beta.9, the login credentials used during the third-party login process are accidentally recorded in the local log file. Although the log file is not automatically uploaded or shared, if the user manually sends the log file, there is a risk of leakage. This is fixed in version 2.12.0-beta.10.
