This bug would allow unsanitized HTTP requests to access arbitrary files on the machine of a yard server host under certain conditions.\n\nThe original patch in GHSA-xfhh-rx56-rxcr was incorrectly applied.\n\n### Patches\n\nPlease upgrade to YARD v0.9.42 immediately if you are relying on yard server to host documentation in any untrusted environments without WEBrick and rely on `--docroot`.\n\n### Workarounds\n\nFor users who cannot upgrade, it is possible to perform path sanitization of HTTP requests at your webserver level. WEBrick, for example, can perform such sanitization by default (which you can use via yard server -s webrick), as can certain rules in your webserver configuration.","public_affected_ranges":["< 0.9.42"]}],"null_published_at":"2026-11-07T07:07:39.832Z","source_updated_at":"2026-05-29T21:44:56.000Z","source_disclosed_at":"2026-04-17T22:21:03.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-07T00:53:14.635Z"}],"next_cursor":null,"snapshot_revision":"42594"}
