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-2026-116887/ (Markdown: https://insights.sbomify.com/CVE-2026-116887/index.md)","id":"CVE-2026-116887","markdown":"https://insights.sbomify.com/CVE-2026-116887/index.md","name":"CVE-2026-116887","record":{"aliases":["GHSA-4vg5-q837-f88q","GHSA-r7xx-9gqh-q8p9"],"analysis":null,"analysis_generated_by":null,"assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Semantic MediaWiki from 3.0.0 before 7.3.1 contains a stored cross-site scripting vulnerability that allows users with page-edit rights to inject HTML through Keyword-typed property values rendered unescaped on Special:Browse.
