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-2026-116269/ (Markdown: https://insights.sbomify.com/CVE-2026-116269/index.md)","id":"CVE-2026-116269","markdown":"https://insights.sbomify.com/CVE-2026-116269/index.md","name":"CVE-2026-116269","record":{"aliases":["DEBIAN-CVE-2026-116269","GHSA-h2xx-9xmf-ppmv","UBUNTU-CVE-2026-116269"],"analysis":null,"analysis_generated_by":null,"assigner":"CPANSec","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[{"id":"CWE-436","name":"Interpretation Conflict"}],"description":"MIME::Field::ParamVal versions before 5.521 for Perl turn an RFC 2231 filename with a hyphenated language tag into an empty recommended filename.\n\nA parameter such as filename*=utf-8'en-US'payload.exe is converted to an encoded word with the language tag appended to the charset.
