An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55871 exists.\n\nAffected product: mayerbalintdev GYM-One. 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-2026-55871/ (Markdown: https://insights.sbomify.com/CVE-2026-55871/index.md)","id":"CVE-2026-55871","markdown":"https://insights.sbomify.com/CVE-2026-55871/index.md","name":"CVE-2026-55871","record":{"aliases":["GHSA-9j4g-cq35-8997"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"GYM One","requires_auth":"high_privilege","summary":"An authenticated administrator can inject SQL via search fields to read arbitrary data, including password hashes, and potentially write files.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"GYM One is open-source gym management software for fitness centers, personal trainers, and sports clubs.

An authenticated administrator can inject SQL through either search field to read data from arbitrary tables, including user information and password hashes. Depending on database permissions, the same injection may also permit filesystem writes.
