Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-61457 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-2026-61457/ (Markdown: https://insights.sbomify.com/CVE-2026-61457/index.md)","id":"CVE-2026-61457","markdown":"https://insights.sbomify.com/CVE-2026-61457/index.md","name":"CVE-2026-61457","record":{"aliases":["CVE-2026-61606","GHSA-66v2-vxxf-xc3v","GHSA-7wcr-m737-mchr"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS plugin","requires_auth":"low_privilege","summary":"Attackers with media write permissions can upload malicious files using double extensions to achieve remote code execution on Grav CMS installations.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"The Grav API plugin (getgrav/grav-plugin-api) before 1.0.3 contains a file upload extension bypass in the API media controller.
