An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-73562 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mongoose (Bitnami): affected all versions; fixed in 6.13.10, 7.8.10, 8.24.1, 9.7.2\n- mongoose (npm): affected all versions; fixed in 6.13.10\n- mongoose (npm): affected all versions; fixed in 6.13.10\n- mongoose (npm): affected from 7.0.0; fixed in 7.8.10\n- mongoose (npm): affected from 7.0.0; fixed in 7.8.10\n- mongoose (npm): affected from 8.0.0; fixed in 8.24.1\n- mongoose (npm): affected from 8.0.0; fixed in 8.24.1\n- mongoose (npm): affected from 9.0.0; fixed in 9.7.2\n- mongoose (npm): affected from 9.0.0; fixed in 9.7.2\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-2026-73562/ (Markdown: https://insights.sbomify.com/CVE-2026-73562/index.md)","id":"CVE-2026-73562","markdown":"https://insights.sbomify.com/CVE-2026-73562/index.md","name":"CVE-2026-73562","record":{"aliases":["BIT-mongoose-2026-73562","CLSA-2026-1785380878","CLSA-2026-1789641939","CLSA-2026-1789641946","CLSA-2026-1789645446","CLSA-2026-1789647573","CLSA-2026-1792188893","CLSA-2026-1792475862","GHSA-664h-wqgq-64gw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB ODM library","requires_auth":"none","summary":"Attackers can pollute Object.prototype via crafted update queries, causing application integrity and availability issues in Mongoose applications.","user_interaction":"not_required","vuln_class":"other"},"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:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Prior to 6.13.10, 7.8.10, 8.24.1, and 9.7.2, passing a user-controlled update such as MyModel.updateOne(filter, req.body) can exploit Mongoose update casting with a __proto__.x dotted path under $set. Schema.prototype.path and Schema.prototype._getPathType can treat inherited properties of schema.paths and schema.nested as schema types, allowing the casting process to set $fullPath and $parentSchemaDocArray on Object.prototype before throwing. This prototype pollution makes those properties visible on newly created objects and can cause application integrity and availability impacts.
