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-2025-13427 in the wild and no public exploit code.\n\nAffected product: Google Cloud Dialogflow CX Messenger. 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-2025-13427/ (Markdown: https://insights.sbomify.com/CVE-2025-13427/index.md)","id":"CVE-2025-13427","markdown":"https://insights.sbomify.com/CVE-2025-13427/index.md","name":"CVE-2025-13427","record":{"aliases":["GHSA-p5gx-f9rx-95rw"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Dialogflow CX Messenger","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to access restricted chat agent knowledge and trigger intents in Google Cloud Dialogflow CX Messenger.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GoogleCloud","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An authentication bypass vulnerability in Google Cloud Dialogflow CX Messenger allowed unauthenticated users to interact with restricted chat agents, gaining access to the agents' knowledge and the ability to trigger their intents, by manipulating initialization parameters or crafting specific API requests. \n\nAll versions after August 20th, 2025 have been updated to protect from this vulnerability.
