This link is maintained to preserve external references.\n\n## Original Description\nTraefik versions = v3.6.0 = v3.7.0 <= v3.7.6 contain an authentication bypass via path traversal in the ReplacePathRegex middleware. When ReplacePathRegex is configured with a regex that captures user-controlled path segments without a mandatory path separator (e.g. regex \"^/api(.*)\", replacement \"/$1\"), the middleware forwards the replaced path to the backend without validating that it matches its normalized form. An unauthenticated remote attacker can send a crafted request (e.g. GET /api../admin) that produces an un-normalized path such as /../admin, which a backend that normalizes paths resolves to a protected route, bypassing authentication middleware. Fixed in v2.11.52, v3.6.23, and v3.7.7.","public_affected_ranges":["<= 2.11.51"]}],"null_published_at":"2026-11-03T10:03:26.566Z","source_updated_at":"2026-08-06T16:50:46.000Z","source_disclosed_at":"2026-07-22T12:32:18.000Z","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":"2026-11-03T02:28:46.523Z"}],"next_cursor":null,"snapshot_revision":"42594"}
