An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-5430 in the wild since at least 24 Sep 2026.\n\nAffected product: Wso2 Api Manager. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-5430/ (Markdown: https://insights.sbomify.com/CVE-2026-5430/index.md)","id":"CVE-2026-5430","markdown":"https://insights.sbomify.com/CVE-2026-5430/index.md","name":"CVE-2026-5430","record":{"aliases":["GHSA-j7vh-5w8q-4m4x"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WSO2 API Manager","requires_auth":"none","summary":"Attackers can bypass authentication by crafting JWTs with unsupported algorithms, leading to unauthorized access and potential administrative account takeover in WSO2 products.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WSO2","cpe":[{"product":"api_control_plane","vendor":"wso2"},{"product":"api_manager","vendor":"wso2"},{"product":"traffic_manager","vendor":"wso2"},{"product":"universal_gateway","vendor":"wso2"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"The JWT authentication mechanism accepts tokens signed with algorithms other than those explicitly configured or supported.
