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-2025-20255 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings. 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-2025-20255/ (Markdown: https://insights.sbomify.com/CVE-2025-20255/index.md)","id":"CVE-2025-20255","markdown":"https://insights.sbomify.com/CVE-2025-20255/index.md","name":"CVE-2025-20255","record":{"aliases":["GHSA-jrwq-36rx-842c"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Webex Meetings","requires_auth":"none","summary":"An unauthenticated remote attacker can poison HTTP caches in Cisco Webex Meetings, causing clients to receive incorrect responses.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_meetings","vendor":"cisco"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-349","name":"Acceptance of Extraneous Untrusted Data With Trusted Data"}],"description":"A vulnerability in client join services of Cisco Webex Meetings could allow an unauthenticated, remote attacker to manipulate cached HTTP responses within the meeting join service.\r\n\r This vulnerability is due to improper handling of malicious HTTP requests to the affected service.
