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-2026-21854 exists.\n\nAffected product: the-hideout tarkov-data-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-2026-21854/ (Markdown: https://insights.sbomify.com/CVE-2026-21854/index.md)","id":"CVE-2026-21854","markdown":"https://insights.sbomify.com/CVE-2026-21854/index.md","name":"CVE-2026-21854","record":{"aliases":["GHSA-r8w6-9xwg-6h73"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Tarkov Data Manager","requires_auth":"none","summary":"Unauthenticated attackers can gain full admin access to the Tarkov Data Manager panel via a prototype pollution and type coercion flaw in the login endpoint.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tarkov_data_manager","vendor":"tarkov"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"},{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"The Tarkov Data Manager is a tool to manage the Tarkov item data.
