Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-36550 in the wild and no public exploit code.\n\nAffected product: Tiki Tikiwiki Cms\\/Groupware. 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-2021-36550/ (Markdown: https://insights.sbomify.com/CVE-2021-36550/index.md)","id":"CVE-2021-36550","markdown":"https://insights.sbomify.com/CVE-2021-36550/index.md","name":"CVE-2021-36550","record":{"aliases":["GHSA-p2g9-2cpx-8r4g"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TikiWiki CMS","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary web scripts via a crafted payload in the Create category module of TikiWiki.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tikiwiki_cms\\/groupware","vendor":"tiki"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"TikiWiki v21.4 was discovered to contain a cross-site scripting (XSS) vulnerability in the component tiki-browse_categories.php.
