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-2026-77607 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mediawiki/semantic-media-wiki (Packagist): affected all versions; fixed in 7.2.0\n- mediawiki/semantic-media-wiki (Packagist): affected all versions; fixed in 7.2.0\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-2026-77607/ (Markdown: https://insights.sbomify.com/CVE-2026-77607/index.md)","id":"CVE-2026-77607","markdown":"https://insights.sbomify.com/CVE-2026-77607/index.md","name":"CVE-2026-77607","record":{"aliases":["GHSA-7xv3-gf2g-498h"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki extension","requires_auth":"none","summary":"An attacker can inject malicious HTML via the separator parameter in Semantic MediaWiki's Special:Ask table, leading to cross-site scripting.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages.
