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-2026-32301 exists.\n\nAffected packages and fixed versions:\n- github.com/centrifugal/centrifugo (Go): affected all versions; no fix listed\n- github.com/centrifugal/centrifugo (Go): affected all versions up to 2.4.0; no fix listed\n- github.com/centrifugal/centrifugo (Go): affected all versions up to 2.4.0; no fix listed\n- github.com/centrifugal/centrifugo/v3 (Go): affected all versions; no fix listed\n- github.com/centrifugal/centrifugo/v3 (Go): affected all versions up to 3.2.3; no fix listed\n- github.com/centrifugal/centrifugo/v3 (Go): affected all versions up to 3.2.3; no fix listed\n- github.com/centrifugal/centrifugo/v4 (Go): affected all versions; no fix listed\n- github.com/centrifugal/centrifugo/v4 (Go): affected all versions up to 4.1.5; no fix listed\n- github.com/centrifugal/centrifugo/v4 (Go): affected all versions up to 4.1.5; no fix listed\n- github.com/centrifugal/centrifugo/v5 (Go): affected all versions; no fix listed\n- github.com/centrifugal/centrifugo/v5 (Go): affected all versions up to 5.4.9; no fix listed\n- github.com/centrifugal/centrifugo/v5 (Go): affected all versions up to 5.4.9; no fix listed\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-2026-32301/ (Markdown: https://insights.sbomify.com/CVE-2026-32301/index.md)","id":"CVE-2026-32301","markdown":"https://insights.sbomify.com/CVE-2026-32301/index.md","name":"CVE-2026-32301","record":{"aliases":["GHSA-j77h-rr39-c552","GO-2026-4702"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Real-time messaging server","requires_auth":"none","summary":"An unauthenticated attacker can trigger SSRF in Centrifugo by crafting JWT claims that influence the dynamic JWKS endpoint URL before signature verification.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"centrifugo","vendor":"centrifugal"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Centrifugo is an open-source scalable real-time messaging server. Prior to 6.7.0, Centrifugo is vulnerable to Server-Side Request Forgery (SSRF) when configured with a dynamic JWKS endpoint URL using template variables (e.g. {{tenant}}). An unauthenticated attacker can craft a JWT with a malicious iss or aud claim value that gets interpolated into the JWKS fetch URL before the token signature is verified, causing Centrifugo to make an outbound HTTP request to an attacker-controlled destination.
