Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-100902 exists.\n\nAffected product: Barco ClickShare CX-20 Gen2. 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-2026-100902/ (Markdown: https://insights.sbomify.com/CVE-2026-100902/index.md)","id":"CVE-2026-100902","markdown":"https://insights.sbomify.com/CVE-2026-100902/index.md","name":"CVE-2026-100902","record":{"aliases":["GHSA-q2rq-5hf8-g6jh"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"ClickShare presentation system","requires_auth":"low_privilege","summary":"Remote attackers can exploit improper input validation in the wallpaper upload feature to potentially execute code or escalate privileges on Barco ClickShare devices.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-1286","name":"Improper Validation of Syntactic Correctness of Input"}],"description":"A vulnerability was determined in Barco ClickShare CX-20 Gen2 up to 02.26.00.0007.
