CyberRota Analysis
AI-GeneratedThe vulnerability arises in the Print Assumptions feature, which fails to indicate when a definition is created without universe checking, allowing for unsafe operations to be inlined without detection. This can lead to the erroneous proof of false statements, as the audit process may incorrectly validate these proofs as sound. Developers using the affected module implementations, particularly those not employing the standalone checker coqchk, should prioritize addressing this issue to prevent potential logical inconsistencies in their proofs.

Original NVD Description
Print Assumptions does not report that a definition was produced while universe checking was disabled when that definition reaches the caller through Parameter Inline in a module type. Applying a functor inlines the body of the parameter, and the inlining drops the record that the term was built under Unset Universe Checking, so the resulting constant carries no trace of the unsafe operation. A module implementation can therefore prove False using a universe inconsistency, expose it through an inlined parameter, and have Print Assumptions report the dependent proof as closed under the global context. Because Print Assumptions is the in-process audit used to confirm that a development rests on no unexpected assumptions, a dependency built this way passes that audit while proving arbitrary propositions. The standalone checker coqchk does reject the resulting compiled file. The project records this in dev/doc/critical-bugs.md under non-fixed bugs and rates the risk as moderate when coqchk is not used.
