High 8.7
In plain English
A high-severity incorrect authorization in QGIS from qgis. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 40% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code.
Official description
QGIS is a free, open source, cross platform geographical information system (GIS) The repository contains a GitHub Actions workflow called "pre-commit checks" that, before commit 76a693cd91650f9b4e83edac525e5e4f90d954e9, was vulnerable to remote code execution and repository compromise because it used the `pull_request_target` trigger and then checked out and executed untrusted pull request code in a privileged context. Workflows triggered by `pull_request_target` ran with the base repository's credentials and access to secrets. If these workflows then checked out and executed code from the head of an external pull request (which could have been attacker controlled), the attacker could have executed arbitrary commands with elevated privileges. This insecure pattern has been documented as a security risk by GitHub and security researchers. Commit 76a693cd91650f9b4e83edac525e5e4f90d954e9 removed the vulnerable code.
