An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-53624 exists.\n\nAffected packages and fixed versions:\n- github.com/gofiber/fiber (Go): affected all versions; fixed in 3.4.0\n- github.com/gofiber/fiber (Go): affected all versions; fixed in 3.4.0\n- github.com/gofiber/fiber/v3 (Go): affected all versions; fixed in 3.4.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-53624/ (Markdown: https://insights.sbomify.com/CVE-2026-53624/index.md)","id":"CVE-2026-53624","markdown":"https://insights.sbomify.com/CVE-2026-53624/index.md","name":"CVE-2026-53624","record":{"aliases":["GHSA-gv83-gqw6-9j2c","GO-2026-5912","MINI-6rv7-gfj9-hp3g","MINI-f7p5-wxxr-c3fg","UBUNTU-CVE-2026-53624"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Go web framework","requires_auth":"none","summary":"Attackers can bypass HSTS protection in Fiber's helmet middleware because the header is never set, allowing potential protocol downgrade attacks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fiber","vendor":"gofiber"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"Fiber is an Express inspired web framework written in Go.
