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-2026-81335 in the wild and no public exploit code.\n\nAffected product: Baserow. 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-2026-81335/ (Markdown: https://insights.sbomify.com/CVE-2026-81335/index.md)","id":"CVE-2026-81335","markdown":"https://insights.sbomify.com/CVE-2026-81335/index.md","name":"CVE-2026-81335","record":{"aliases":["GHSA-h84g-8x85-mw8v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Baserow no-code database","requires_auth":"none","summary":"Unauthenticated attackers can access sensitive data from Builder data sources due to a missing permission check enforcement in Baserow.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Baserow dispatches an Application Builder data source without acting on the result of its permission check. The dispatch and record-name views in backend/src/baserow/contrib/builder/api/data_sources/views.py are declared with a permission class that admits any caller, so a request carrying no credential reaches the handler. DataSourceService.dispatch_data_sources in backend/src/baserow/contrib/builder/data_sources/service.py then calls check_multiple_permissions without asking it to raise, and neither stores nor examines the mapping of denials it returns, so a denied check leaves execution to continue and the data source is dispatched whatever the caller's identity. The dispatch runs with the integration's own credentials, so an unauthenticated request naming a data source receives the rows and fields that source reads. Identifiers are small integers and can be enumerated.
