An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-8wgc-jjvv-cv6v in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- loopback (npm): affected all versions; fixed in 2.40.0\n- loopback (npm): affected all versions; fixed in 2.40.0\n- loopback (npm): affected from 3.0.0; fixed in 3.22.0\n- loopback (npm): affected from 3.0.0; fixed in 3.22.0\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/GHSA-8wgc-jjvv-cv6v/ (Markdown: https://insights.sbomify.com/GHSA-8wgc-jjvv-cv6v/index.md)","id":"GHSA-8wgc-jjvv-cv6v","markdown":"https://insights.sbomify.com/GHSA-8wgc-jjvv-cv6v/index.md","name":"GHSA-8wgc-jjvv-cv6v","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Node.js web framework","requires_auth":"none","summary":"Attackers can create authentication tokens for any user if the AccessToken model is exposed, leading to unauthorized data access and privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Vulnerable versions of `loopback` may allow attackers to create Authentication Tokens on behalf of other users due to Improper Authorization.
