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 GHSA-gqqf-g5r7-84vf in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.32\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.32\n- typo3/cms-core (Packagist): affected from 11.0.0; fixed in 11.5.16\n- typo3/cms-core (Packagist): affected from 11.0.0; fixed in 11.5.16\n- typo3/cms-core (Packagist): affected from 7.0.0; fixed in 7.6.58\n- typo3/cms-core (Packagist): affected from 7.0.0; fixed in 7.6.58\n- typo3/cms-core (Packagist): affected from 8.0.0; fixed in 8.7.48\n- typo3/cms-core (Packagist): affected from 8.0.0; fixed in 8.7.48\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.37\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.37\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-gqqf-g5r7-84vf/ (Markdown: https://insights.sbomify.com/GHSA-gqqf-g5r7-84vf/index.md)","id":"GHSA-gqqf-g5r7-84vf","markdown":"https://insights.sbomify.com/GHSA-gqqf-g5r7-84vf/index.md","name":"GHSA-gqqf-g5r7-84vf","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"none","summary":"Attackers can bypass XSS protection in TYPO3 via malicious HTML comments, potentially executing scripts in victim browsers.","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":"\u003e ### Meta\n\u003e * CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C` (5.7)\n\n### Problem\nDue to a parsing issue in upstream package [`masterminds/html5`](https://packagist.org/packages/masterminds/html5), malicious markup used in a sequence with special HTML comments cannot be filtered and sanitized.
