The record
A path traversal vulnerability was discovered in YARD <= 0.9.41 when using yard server to serve documentation. This bug would allow unsanitized HTTP requests to access arbitrary files on the machine of a yard server host under certain conditions. The original patch in [GHSA-xfhh-rx56-rxcr](https://github.com/lsegal/yard/security/advisories/GHSA-xfhh-rx56-rxcr) was incorrectly applied.
