An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-111881 exists.\n\nAffected product: FreeRDP. 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-2026-111881/ (Markdown: https://insights.sbomify.com/CVE-2026-111881/index.md)","id":"CVE-2026-111881","markdown":"https://insights.sbomify.com/CVE-2026-111881/index.md","name":"CVE-2026-111881","record":{"aliases":["DEBIAN-CVE-2026-111881","GHSA-27m7-gwhh-6hhf","GHSA-45g6-44vr-p7wm","UBUNTU-CVE-2026-111881"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeRDP library","requires_auth":"none","summary":"A malicious RDP clipboard peer can trigger an integer underflow in FreeRDP, causing a crash or out-of-bounds write via crafted BMP images.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"FreeRDP from 3.14.1 before 3.32.0 contains an integer underflow in the WinPR BMP writer, where a mismatched stride calculation passes SIZE_MAX - 3 to Stream_Zero for sub-byte images.
