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-2026-58656 exists.\n\nAffected product: getgrav grav. 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-2026-58656/ (Markdown: https://insights.sbomify.com/CVE-2026-58656/index.md)","id":"CVE-2026-58656","markdown":"https://insights.sbomify.com/CVE-2026-58656/index.md","name":"CVE-2026-58656","record":{"aliases":["GHSA-fx5h-wv8r-5j9q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS API plugin","requires_auth":"none","summary":"Attackers can hijack admin accounts and steal data by exploiting CORS wildcards and JWT tokens passed via URL query parameters in the Grav API plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-598","name":"Use of HTTP Request With Sensitive Query String"}],"description":"Grav API plugin before v1.0.0-rc.16 accepts JWT tokens via the ?token= URL query parameter and responds with Access-Control-Allow-Origin: *, allowing unauthenticated attackers to make fully authenticated cross-origin API requests from any malicious website.
