An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of GHSA-76r3-m635-p3vc in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms-core (Packagist): affected from 9.2.0; fixed in 9.5.4\n- typo3/cms-core (Packagist): affected from 9.2.0; fixed in 9.5.4\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/GHSA-76r3-m635-p3vc/ (Markdown: https://insights.sbomify.com/GHSA-76r3-m635-p3vc/index.md)","id":"GHSA-76r3-m635-p3vc","markdown":"https://insights.sbomify.com/GHSA-76r3-m635-p3vc/index.md","name":"GHSA-76r3-m635-p3vc","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"high_privilege","summary":"An attacker can execute arbitrary scripts in the TYPO3 install tool via malicious language packs, potentially compromising the installation process.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Failing to properly encode information from external sources, language pack handling in the install tool is vulnerable to cross-site scripting.","ecosystems":["Packagist"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"TYPO3 Cross-Site Scripting in Language Pack Handling","id":"GHSA-76r3-m635-p3vc","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2024"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"Packagist","fixed":["9.5.4"],"introduced":["9.2.0"],"last_affected":[],"package":"typo3/cms-core","purl":null,"source":"GHSA-76r3-m635-p3vc"},{"ecosystem":"Packagist","fixed":["9.5.4"],"introduced":["9.2.0"],"last_affected":[],"package":"typo3/cms-core","purl":"pkg:composer/typo3/cms-core","source":"GHSA-76r3-m635-p3vc"}],"products":null,"published":"2024-05-30","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can execute arbitrary scripts in the TYPO3 install tool via malicious language packs, potentially compromising the installation process.","url":"https://insights.sbomify.com/GHSA-76r3-m635-p3vc/"}
