An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-92359 in the wild and no public exploit code.\n\nAffected product: ag-ui-protocol ag-ui. 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-2026-92359/ (Markdown: https://insights.sbomify.com/CVE-2026-92359/index.md)","id":"CVE-2026-92359","markdown":"https://insights.sbomify.com/CVE-2026-92359/index.md","name":"CVE-2026-92359","record":{"aliases":["GHSA-fq29-84pr-2m3x"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python AI protocol library","requires_auth":"none","summary":"An attacker can bypass cross-domain restrictions due to permissive CORS policies in the ag-ui-protocol library, potentially enabling unauthorized cross-origin requests.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X","version":"4.0"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"},{"id":"CWE-346","name":"Origin Validation Error"}],"description":"A security flaw has been discovered in ag-ui-protocol ag-ui 0.3.0.

The manipulation results in permissive cross-domain policy with untrusted domains. The attack may be launched remotely. The attack requires a high level of complexity. The exploitability is described as difficult. Upgrading to version AGUI.Abstractions@0.0.6 is sufficient to fix this issue. The patch is identified as 9b143b9668fa52c2054ede9d34a45ac4b4401089.
