Compiler Explorer allows remote users to compile and, if configured, execute code. We take security seriously, and encourage users to promptly report security vulnerabilities they find.
If the issue can be reported without revealing exploitable specifics, please file an issue as a bug.
Please email matt@godbolt.org with specifics, or if the bug can't be reported publically without leaving an obvious exploit in the public eye.
We expect to get back within a day or two. If you don't hear from us, please do ping us again, or reach out to us on the Discord.
