In github.com/gofiber/fiber/v3 versions through 3.1.0, the default key generator in the cache middleware uses only the request path and does not include the query string. As a result, requests for the same path with different query parameters can share a cache key and receive the wrong cached response. This can cause response mix-up for query-dependent endpoints and may expose data intended for a different request. This issue is fixed after version 3.1.0."}], "lastModified": "2026-06-17T10:32:33.373", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:gofiber:fiber:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "F4D5D7B6-2F8B-461E-B59A-BAD18731F429", "versionEndIncluding": "3.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
